Hosted checkout vs API checkout: which payment integration is right for your business?

The choice between hosted checkout and API checkout shapes how a payment stack handles every transaction. It determines PCI compliance burden, conversion potential, branding flexibility, mobile experience, how quickly new payment methods can be added, and whether the merchant can route across multiple PSPs without rebuilding. For enterprise merchants, the decision is also rarely binary, with most production payment stacks ending up using a combination of integration methods for different surfaces and transaction types.

Learn the five practical integration patterns merchants choose between in 2026 (hosted checkout, hosted fields, full API, mobile SDK, and payment links), compare them across every dimension that matters, to make a decision framework based on merchant profile, technical capacity, and business priorities. The framing throughout assumes a multi-PSP, orchestration-aware payment stack rather than a single-provider integration, because that is increasingly the architecture that most enterprise merchants operate under.

The five integration patterns at a glance

Before the deeper analysis, the short version of each option:

• Hosted checkout redirects the customer to a payment page hosted by the PSP or orchestration platform. Customers leave the merchant’s site for the payment step. Fastest to deploy, lowest PCI scope, lowest branding control.
• Hosted fields embeds secure payment input fields inside the merchant’s own checkout page. Customers stay on the merchant’s site, but card data is captured inside iframes served by the PSP or vault provider. Best balance of control and compliance.
• Full API integration uses REST APIs and SDKs to handle every aspect of the payment flow. Maximum control and branding flexibility, highest PCI compliance burden.
• Mobile SDK provides native iOS and Android components that handle in-app payment collection. Optimized for mobile-first experiences with biometric authentication and digital wallets.
• Payment links generate shareable URLs that route to a pre-configured payment page. Used for invoicing, social commerce, B2B billing, agentic flows, and any scenario where the buyer is not present at a traditional checkout.

The choice is not strictly between “hosted” and “API.” Modern payment stacks combine these patterns based on which surface the transaction is happening on, which PSP will process it, and what the business priorities are at that touchpoint.

What is hosted checkout?

A hosted checkout solution sends the customer to a payment page hosted on the PSP’s or orchestration platform’s infrastructure. The merchant’s site redirects to the hosted page, the customer completes payment there, and the customer returns to the merchant’s site after the transaction is finished or canceled.

The merchant never sees or stores card data. The PCI compliance burden is mostly absorbed by the PSP or platform, which means the merchant typically qualifies for a simpler PCI Self-Assessment Questionnaire (SAQ A) rather than a full PCI DSS audit. Setup time is hours to days for most platforms, and the integration is usually configuration-driven rather than code-heavy.

Where hosted checkout works well:

• Merchants with limited engineering bandwidth or compressed time-to-launch requirements
• Subscription businesses where checkout happens infrequently and the brand impact of a redirect is acceptable
• Smaller merchants whose volume does not justify investment in custom payment UX
• B2B sales flows where the buyer expects to leave the marketing site to complete a purchase
• Markets where the PSP’s hosted page already supports a strong selection of local payment methods

The limitations of hosted checkout:

• Customers experience a domain change during the payment step, which can introduce trust friction. Approximately 70% of checkout abandonment stems from trust concerns during transitions, according to industry research, making the redirect a measurable conversion cost in some segments.
• Branding control is limited to whatever customization the PSP allows (typically logo, colors, and some copy adjustments)
• Conversion rate optimization is harder because the merchant does not control the entire checkout funnel
• Complex payment flows (split payments, escrow, conditional captures) often cannot be expressed inside a hosted page
• Multi-PSP routing requires the hosted page itself to be PSP-agnostic, which is only true for orchestration platforms

For a deeper view of how to optimize the checkout experience regardless of integration model, see Gr4vy’s guide on checkout optimization strategies.

What is API checkout?

A full API integration uses REST APIs, server SDKs, and client-side JavaScript to build the entire payment flow inside the merchant’s environment. The customer never leaves the merchant’s site, no redirect happens, and every pixel of the payment experience is under the merchant’s control.

The trade-off is responsibility. With full API integration, card data flows through the merchant’s infrastructure, which means the merchant typically operates under PCI DSS SAQ D requirements (the most comprehensive Self-Assessment Questionnaire) and must maintain a PCI Level 1 compliant environment if transaction volumes exceed scheme thresholds. The compliance overhead is significant, with annual costs that can run from $100,000 to several hundred thousand dollars for enterprise merchants.

Where API checkout works well:

• Enterprise merchants with established payments engineering teams and budget for PCI compliance
• Marketplaces and platforms with complex payment flows that hosted pages cannot accommodate
• Brands where checkout is a meaningful part of the customer experience and the conversion impact of full UX control justifies the engineering investment
• Subscription, usage-based, and recurring businesses where billing logic is tightly coupled to product logic
• Mobile-heavy businesses where native integration through SDKs is essential

The limitations of full API checkout:

• The engineering investment is substantial, with implementation timelines typically running 3-6 months for a comprehensive integration
• PCI DSS audit scope is significantly broader, with all associated cost and operational overhead
• The merchant takes on responsibility for fraud screening, 3D Secure orchestration, error handling, and security patching of the payment surfaces
• Adding new payment methods requires development work for each one, slowing time-to-market for international expansion
• Ongoing maintenance burden is meaningful, since payment APIs evolve and the merchant’s integration has to evolve with them

Hosted fields: the underserved middle option

Most articles compare hosted checkout to full API integration as if those were the only two choices. There is a third option that combines most of the advantages of each: hosted fields.

A hosted fields integration embeds secure iframes inside the merchant’s own checkout page, with each iframe controlled by the PSP or vault provider. The customer sees what appears to be the merchant’s checkout page, but the actual card-number, expiration, and CVV inputs are running inside iframes hosted on the PSP’s domain. Card data flows directly from the customer’s browser to the PSP, never touching the merchant’s servers.

The result is PCI scope reduction similar to a hosted page (SAQ A in most implementations) combined with branding control similar to a full API integration. The customer never sees a domain change. The merchant designs the checkout page exactly as they want it. The card-input fields look and feel native to the merchant’s brand, with only the PSP-controlled inputs being technically separate.

Where hosted fields work well:

• Enterprise merchants who want to minimize PCI scope while preserving full UX control
• Brands where checkout is a measurable conversion driver and even a redirect would be costly
• Multi-PSP setups where the hosted fields can be swapped dynamically based on routing decisions
• International expansion scenarios where compliance overhead in new markets needs to be contained

The trade-offs:

• Implementation complexity sits between hosted checkout and full API, with timelines typically 1-3 months
• Browser compatibility and iframe handling require more QA than a redirect-based hosted page
• Some PSPs implement hosted fields differently, which means switching providers can require front-end work
• The PCI scope reduction depends on correct implementation; misconfigured iframes can pull additional pages into PCI scope

For merchants in the middle of the size and complexity spectrum, hosted fields is often the strongest answer and is increasingly the default pattern enterprise orchestration platforms recommend.

Mobile SDKs: the in-app integration path

A separate but related question is how to handle payments inside native mobile apps. Three options exist: redirect to a hosted page via a web view, embed hosted fields via a web view, or use a native mobile SDK provided by the PSP or orchestration platform.

Mobile SDKs are designed specifically for in-app payment collection. They provide native iOS and Android components that match platform design conventions, integrate with biometric authentication (Touch ID, Face ID, fingerprint), handle Apple Pay and Google Pay natively, and avoid the web-view friction that hosted pages create on mobile.

Where mobile SDKs are essential:

• Apps with significant transaction volume where the in-app experience materially affects conversion
• Subscription apps where biometric reauthorization is a meaningful retention signal
• Apps targeting markets where digital wallets are dominant (Apple Pay in the US, Google Pay across Android markets, regional wallets globally)
• Any app where Apple Pay or Google Pay needs to be a primary payment method

The compliance posture of mobile SDKs varies by implementation. Most modern mobile SDKs from major orchestration platforms keep card data inside the SDK’s secure context, avoiding direct exposure to the merchant’s app code, which maintains a reduced PCI scope similar to hosted fields.

For a deeper look at mobile-specific patterns, see Gr4vy’s guide on mobile checkout best practices.

Payment links: the asynchronous integration path

The fifth integration pattern is payment links, which are shareable URLs that route to a pre-configured payment page. The merchant generates a link through an API or dashboard, sends it via email, SMS, chat, or any other channel, and the recipient completes payment when they choose.

Payment links work alongside hosted checkout and API integration rather than replacing them, handling the cases where a traditional checkout flow does not fit:

• Invoicing and B2B billing: send the link in the invoice email, the buyer pays when ready
• Social commerce: share the link in Instagram DMs, WhatsApp, or social posts
• Voice and phone commerce: read the link to a customer over the phone or send via SMS
• Agentic flows: the AI agent generates a payment link for the buyer to authorize asynchronously
• Pop-up and event commerce: sales surfaces where embedding a checkout is impractical

Industry data suggests payment links can unlock 7% or more additional revenue for merchants who add them to their stack, by serving transaction scenarios that traditional checkout patterns cannot address. They are also the simplest integration path: a single API call generates a fully functional payment page.

The definitive comparison

The five integration patterns across every dimension that matters for a merchant evaluation:

Dimension	Hosted checkout	Hosted fields	Full API	Mobile SDK	Payment links
Customer experience	Redirect to PSP page	Stays on merchant site, fields in iframes	Fully native to merchant site	Native in-app	Recipient-driven, asynchronous
PCI scope	SAQ A (minimal)	SAQ A (minimal)	SAQ D (full)	SAQ A typically	SAQ A (minimal)
Branding control	Limited	High	Full	Native to platform	Configurable, PSP-hosted
Time to deploy	Hours to days	1-3 months	3-6 months	1-3 months	Hours
Engineering effort	Low	Medium	High	Medium-High	Very low
Conversion potential	Lower (redirect friction)	High	Highest	Very high in-app	High for fit use cases
Multi-PSP routing	Requires orchestration	Yes, via orchestration	Yes, requires routing layer	Yes, via orchestration	Yes, via orchestration
Mobile experience	Acceptable	Good (with mobile-optimized fields)	Good	Best	Excellent (recipient device-native)
Apple Pay / Google Pay	Limited customization	Yes	Yes	Native	Yes
Custom payment flows	Limited	Possible	Full flexibility	Full flexibility	Limited to single transactions
3D Secure handling	Managed by PSP	Managed by PSP	Merchant-implemented	Managed by SDK	Managed by PSP
Best for	Fast launch, low-volume, simple flows	Most enterprise checkouts	Complex platforms, marketplaces	Mobile-first businesses	Invoicing, B2B, async commerce

The pattern that emerges from the table: hosted fields is the strongest default for most enterprise merchants, with mobile SDK for native app surfaces, payment links for asynchronous use cases, and full API only where the complexity genuinely justifies the overhead.

When to choose hosted checkout

Choose hosted checkout when one or more of these apply:

• You are launching quickly. The hours-to-days deployment time is unmatched, and getting payments live is more important than optimizing them.
• You have limited engineering bandwidth. Hosted checkout requires the least ongoing maintenance and shifts most of the operational burden to the PSP or orchestration platform.
• Your PCI compliance posture is the priority. SAQ A is significantly less expensive and less operationally demanding than SAQ D, and hosted pages achieve this cleanly.
• Your transactions are infrequent or one-off. Subscription renewals, donation flows, ticket sales, and similar use cases where the checkout is not the brand experience.
• The PSP’s hosted page already supports your needed payment methods. International expansion is significantly faster when local methods are included in the hosted page by default.
• You operate in regulated industries where reducing data handling responsibility is a strategic priority. Healthcare, financial services, and government often default to hosted patterns specifically to limit PCI scope.

When to choose full API

Choose full API integration when one or more of these apply:

• Checkout is a meaningful part of the brand experience. Luxury retail, premium subscription services, and DTC brands where even a domain change is a measurable conversion cost.
• You operate a marketplace or platform with complex payment flows. Split payments, escrow, conditional captures, marketplace payouts, and other patterns that hosted pages cannot express.
• You have an established payments engineering team and budget for PCI compliance. SAQ D is workable but expensive, and the team has to be set up to maintain it.
• You need granular control over the payment UX at every step. Custom fraud screening, conditional 3D Secure, dynamic field validation, and similar capabilities that require code-level access.
• You are building agentic commerce flows where the agent needs deep API access. Protocol-level integrations with ChatGPT, Gemini, and other agent platforms typically require full API access. For details, see Gr4vy’s guide on how to make your checkout AI-agent-ready.

When to choose hosted fields (the most common enterprise answer)

For most enterprise merchants, hosted fields is the right default. Choose this pattern when:

• You want PCI scope reduction without sacrificing UX control. Hosted fields achieve SAQ A while keeping customers on the merchant’s site
• Your annual card volume is between $20M and several billion. This range benefits most from the balance hosted fields strike
• You operate across multiple PSPs. Hosted fields can be swapped dynamically based on routing decisions, which is the orchestration pattern most enterprise stacks use
• You want to A/B test checkout designs without backend redeploys. Hosted fields integrate cleanly with experimentation platforms
• You are migrating from a hosted checkout to gain branding control without taking on full PCI scope. This is the most common evolution path from hosted to full API

How orchestration changes the integration decision

The choice between hosted, hosted fields, and full API is often presented as a one-time decision tied to a specific PSP. With payment orchestration, the framing changes meaningfully.

An orchestration layer sits between the merchant’s checkout (whatever its integration model) and the underlying PSPs. The merchant can implement hosted fields once through the orchestration platform, and the platform routes the resulting transactions across multiple PSPs based on configurable rules. The integration model becomes a property of the merchant’s checkout, decoupled from the PSP relationships sitting underneath.

This is meaningful in three ways:

1. Integration choice is no longer locked to PSP choice. A merchant can use hosted fields with Stripe and Adyen simultaneously, with the orchestration platform deciding which PSP processes each transaction. Switching providers does not require rebuilding the checkout.

2. Different integration models can coexist. The web checkout might use hosted fields, the mobile app might use a mobile SDK, and the B2B invoicing might use payment links. All three run on the same underlying PSP relationships and the same routing rules.

3. Migration paths become smoother. A merchant that starts with hosted checkout can migrate to hosted fields without changing their PSP relationships. A merchant on hosted fields can selectively migrate to full API for specific transaction types without rebuilding everything.

This is the architecture Gr4vy’s Checkout product was built around. Hosted checkout, hosted fields, REST APIs, mobile SDKs, plugins, and payment links all sit on top of the same orchestration platform, with routing logic that connects to more than 400 PSPs and payment methods through a single integration.

PCI compliance implications

The PCI compliance burden differs significantly across integration patterns, and the differences directly affect operational cost and audit complexity.

SAQ A is the simplest Self-Assessment Questionnaire. It applies when the merchant fully outsources cardholder data handling to a PCI DSS-validated third party, with the merchant’s own systems never seeing, processing, or transmitting card data. Hosted checkout, well-implemented hosted fields, payment links, and most mobile SDKs qualify for SAQ A. The annual compliance overhead is typically a few thousand dollars and a couple of weeks of internal work.

SAQ A-EP applies when the merchant’s website or mobile app affects the security of the payment page, even though the merchant does not directly handle card data. Some hosted fields implementations fall into this category if the integration code is not isolated from sensitive elements. The compliance burden is higher than SAQ A but still significantly less than SAQ D.

SAQ D is the most comprehensive Self-Assessment Questionnaire, applicable when the merchant directly handles, processes, or transmits cardholder data. Full API integrations almost always fall into SAQ D. The annual compliance cost is meaningful, typically $100,000 to several hundred thousand dollars for enterprise merchants, plus the operational overhead of maintaining a PCI Level 1 compliant environment.

PCI DSS 4.0.1 (the current standard) tightened several requirements around stored card data, third-party script integrity, and authentication. Merchants who operated under SAQ D in 2024 should reassess whether their current architecture still represents the most efficient PCI posture, because the gap between SAQ A and SAQ D has widened. For a deeper view, see Gr4vy’s analysis of PCI DSS compliance and payment orchestration.

Migration paths: how integrations evolve

Most merchants do not stay on the integration they started with. The typical evolution looks like:

Stage 1: Hosted checkout (years 0-2). Fast launch, simple needs, limited engineering capacity. Most merchants begin here.

Stage 2: Hosted fields (years 2-5). As volume grows, the branding limitations and conversion impact of redirect become measurable. Migrating to hosted fields preserves PCI scope reduction while recovering UX control.

Stage 3: Hosted fields plus mobile SDK (years 3-7). Mobile share of revenue grows, and the in-app experience becomes a meaningful conversion driver. Adding a mobile SDK alongside the web hosted fields integration becomes standard.

Stage 4: Hosted fields plus mobile SDK plus payment links (years 4+). B2B, social, voice, and agentic use cases emerge. Payment links handle the asynchronous and non-traditional checkout scenarios that the rest of the stack cannot address.

Stage 5: Selective full API (years 5+, only where justified). Complex payment flows that hosted fields cannot express get migrated to full API. This is rarely a wholesale migration; instead, specific transaction types move to API while the bulk of the volume remains on hosted fields.

The merchants who manage this evolution best are the ones who started with an orchestration platform from the beginning, because the platform decouples the integration model from the PSP relationships and makes each migration step a configuration change rather than a rebuild.

Common integration mistakes to avoid

A handful of patterns separate well-implemented payment stacks from troubled ones:

Choosing full API integration too early. The PCI compliance overhead is significant, and the engineering team that ships the integration is often not the team that has to maintain it long-term. Most merchants under $20M in annual card volume do not yet need the level of control that full API provides, and the operational drag becomes a problem before the strategic value materializes.

Locking the integration model to a single PSP. A hosted page implementation tied to one PSP becomes a multi-month rebuild when the merchant wants to add or switch providers. Implementing through an orchestration platform from the start preserves the flexibility to add PSPs without rebuilding the integration.

Treating mobile as a secondary surface. In most B2C categories, mobile is the majority of revenue. Implementing a web-only integration first and adding mobile later typically produces a worse mobile experience than building mobile-native from the start. The order of priority should reflect where revenue actually comes from.

Skipping hosted fields and going straight from hosted to full API. Many merchants overshoot. The full API integration produces more flexibility than they need, with more PCI scope and engineering overhead. Hosted fields is the right destination for most enterprise checkouts, and the migration from hosted page to hosted fields is significantly faster than the migration from hosted page to full API.

Underestimating the ongoing maintenance burden. Payment integrations are not one-time projects. APIs evolve, security requirements tighten, new payment methods emerge, and the integration has to evolve with them. The team needs to be sized for ongoing maintenance over the long term, with initial implementation being only the first phase of a continuous commitment.

A practical decision matrix

Combining merchant profile with integration choice produces the following starting recommendations:

Merchant profile	Recommended integration	Why
Small or new business (under $1M annual card volume)	Hosted checkout	Fast launch, lowest overhead, focus engineering on product
Growing mid-market merchant ($1-20M)	Hosted checkout, planning migration to hosted fields	Capture volume now, plan UX investment when conversion impact becomes measurable
Enterprise ecommerce ($20M-$1B)	Hosted fields plus mobile SDK	Best balance of UX, PCI, and flexibility
Mobile-first enterprise	Mobile SDK plus hosted fields for web	Match the surface where revenue concentrates
Marketplace or platform	Full API where complexity demands it, hosted fields elsewhere	Complex payment flows require code-level control
B2B with invoicing	Hosted fields plus payment links	Match the buying patterns of B2B customers
Subscription business	Hosted fields plus mobile SDK plus payment links	Cover web, app, and recovery flows
Agentic commerce participant	Full API for agent surfaces, hosted fields for human surfaces	Protocol-level integration requires direct API access

These are starting points to guide further evaluation. The actual decision depends on the specific business priorities, the team’s capabilities, and the existing payment infrastructure. Many enterprise merchants operate combinations of these patterns simultaneously, with each transaction routed through whichever integration best fits the customer surface and the merchant’s priorities at that touchpoint.

Frequently asked questions

What is the difference between hosted checkout and API checkout?

Hosted checkout redirects the customer to a payment page hosted on the PSP’s or orchestration platform’s infrastructure, with the merchant never touching card data. API checkout uses REST APIs and SDKs to handle the entire payment flow inside the merchant’s environment, with the merchant taking on full responsibility for the payment UX and PCI compliance. Hosted checkout is faster to deploy and has lower PCI scope; API checkout offers maximum control and branding flexibility.

Which has higher conversion: hosted checkout or API checkout?

API checkout typically achieves higher conversion because customers stay on the merchant’s site throughout the payment process, avoiding the trust friction that a domain change introduces. Industry research suggests approximately 70% of checkout abandonment stems from trust concerns during transitions, making the redirect in hosted checkout a measurable conversion cost. However, well-implemented hosted fields (a hybrid pattern) achieve conversion close to full API while keeping PCI scope similar to hosted checkout.

Are hosted checkout and hosted payment page the same thing?

Yes, the terms are used interchangeably. Both refer to a payment page hosted on the PSP’s or orchestration platform’s infrastructure, with the customer redirected from the merchant’s site to complete the transaction.

What is the PCI compliance difference between hosted and API checkout?

Hosted checkout typically allows merchants to qualify for PCI DSS SAQ A, the simplest Self-Assessment Questionnaire, because card data never touches the merchant’s systems. API checkout almost always requires SAQ D, the most comprehensive Questionnaire, because the merchant directly handles cardholder data. The annual compliance overhead can differ by an order of magnitude, with SAQ A typically costing a few thousand dollars and SAQ D often costing $100,000 or more for enterprise merchants.

What are hosted fields?

Hosted fields are secure iframes embedded inside the merchant’s own checkout page, with each iframe controlled by the PSP or vault provider. Customers see what appears to be the merchant’s checkout, but the actual card-input fields are technically hosted on the PSP’s domain. The pattern combines PCI scope reduction similar to a hosted page with branding control similar to full API integration, which is why it is increasingly the default for enterprise checkouts.

Can I switch from hosted checkout to API checkout later?

Yes, and most merchants do. The typical evolution is from hosted checkout to hosted fields to selective full API, with mobile SDKs and payment links added along the way. The migration is significantly easier if the merchant started with an orchestration platform, because the underlying PSP relationships do not need to change when the integration model evolves.

Does API checkout support more payment methods than hosted checkout?

Not necessarily. Both patterns can support the same payment methods; the difference is how the merchant configures them. Hosted checkout often includes a pre-built selection of methods that the PSP supports, making international expansion faster. API checkout requires the merchant to integrate each method individually, which produces more flexibility but slower time-to-market for new methods.

How long does it take to integrate hosted checkout vs API checkout?

Hosted checkout typically deploys in hours to days. Hosted fields integrations take 1-3 months. Full API integrations take 3-6 months for a comprehensive implementation. Mobile SDK integrations take 1-3 months. Payment links can be live in hours.

Is hosted checkout less secure than API checkout?

No, the two are equally secure when properly implemented. Both rely on tokenization, encryption, and the underlying PSP’s security infrastructure. The PCI scope is different (hosted checkout reduces the merchant’s compliance burden) but the actual security posture of a well-implemented integration in either model is comparable.

Can I use multiple integration types at once?

Yes, and this is the most common pattern for enterprise merchants. Web checkout might use hosted fields, the mobile app might use a mobile SDK, B2B invoicing might use payment links, and complex marketplace transactions might use full API. An orchestration platform makes this practical because the underlying PSP relationships and routing rules are shared across all the integration surfaces.

What about iframes specifically: are they the same as hosted fields?

Hosted fields are a specific implementation of iframes for payment-input collection. The terms are sometimes used interchangeably, but “hosted fields” usually refers specifically to the pattern where individual card-input fields are isolated in iframes inside an otherwise merchant-controlled checkout page. Other iframe patterns exist (full-page iframe checkouts, redirect iframes) and have different trade-offs.

Does mobile SDK count as hosted or API?

Neither, exactly. Mobile SDKs are a separate integration pattern designed for in-app collection. Most modern mobile SDKs keep card data inside the SDK’s secure context (avoiding direct exposure to the merchant’s app code), which preserves PCI scope similar to hosted fields, while providing the native in-app experience that web-view-based hosted pages cannot match.

Are payment links a replacement for checkout pages?

No, they work as a complementary capability. Payment links handle asynchronous and non-traditional payment scenarios (invoicing, social commerce, voice, agentic flows) that traditional checkout patterns cannot serve. Most merchants who add payment links use them alongside their primary checkout to extend reach into new transaction types.

What to do next

The hosted vs API choice is less binary than most articles present it. The realistic question for most enterprise merchants is which combination of integration patterns best serves which transaction surface, with hosted fields as the default for most web checkouts, mobile SDK for native apps, payment links for asynchronous and B2B scenarios, and full API reserved for the specific cases where complex payment flows justify the overhead.

The architectural decision that matters most is whether all of these integration surfaces share the same underlying PSP relationships and routing rules. Merchants who run each integration on its own dedicated PSP integration multiply their operational complexity, fragment their analytics, and lock themselves into multiple parallel vendor relationships. Merchants who run their integrations on top of an orchestration platform share PSP relationships, share routing logic, and share analytics across every customer surface.
