The new developer frontier: How automated SDKs are reshaping the future of payments

Developer experience isn’t a nice-to-have, it’s a strategic advantage. In a world where speed, flexibility, and scalability define winners, developer experience is more than a feature, it’s a foundational pillar of product strategy.

For payment providers, the ability to integrate quickly and reliably can make or break a merchant’s go-live timeline. That’s why Gr4vy has completely reimagined how we deliver SDKs, moving from manually maintained code to fully automated SDK generation based on our APISpeakeasy.

The result? Less friction. More velocity. And most importantly, a new standard for what enterprise-grade developer tooling should look like.

Traditionally, SDKs were built manually, updated only when someone remembered to sync them with the evolving API spec. This led to version mismatches, broken methods, and a lack of trust from developers.

Gr4vy’s modern approach flips this model on its head. Here’s how it works:

• Single Source of Truth: Our OpenAPI schema is generated directly from our API source, ensuring it reflects the most up-to-date state of our platform.
  
• Automated SDK Generation: Using Speakeasy, we produce six language-specific SDKs (Java, Python, TypeScript, Go, PHP, and C#) from the OpenAPI specification.
  
• Auto-Publishing: New SDKs are automatically versioned, packaged, and published to their respective registries (e.g., npm, PyPI, Maven).
  
• Documentation Alignment: Code samples and SDK references are enriched and injected into our documentation automatically.
  
• Automated Maintenance: The new SDKs automatically receive updates from Speakeasy to ensure no SDK is left with unsafe or outdated dependencies.

This closed feedback loop ensures that changes made in our platform are instantly and accurately reflected in developer-facing resources, eliminating guesswork and reducing integration risk.

What It Means for Developers

For engineers integrating with payment providers, SDKs are the bridge between concept and deployment. Gr4vy’s new SDKs remove much of the complexity that often plagues these workflows:

• Typed Interfaces: Enjoy rich, language-native types with full IDE autocomplete and inline documentation.
  
• Better Errors: Catch problems at compile-time, not runtime.
  
• Consistent Method Signatures: Know what to expect, regardless of which language you’re working in.
  
• Pre-Built Authentication & Error Handling: Built-in support for auth tokens, retries, and response validation speeds up integration time.
  

These SDKs are built not just for convenience, but for confidence.

Documentation That’s Actually Developer-Friendly

SDKs alone aren’t enough, great SDKs need great documentation. That’s why we’ve redesigned our developer portal to equip teams with everything they need to get started quickly and confidently. Each API endpoint now includes language-specific code samples that are auto-generated and always up to date. Developers can test endpoints directly within the docs using our interactive API playground powered by Mintlify. We’ve also embedded support for AI assistants like ChatGPT and Claude on every page to provide instant, contextual support. The navigation has been streamlined as well, with a clear separation between dashboard guides and API references for faster access to relevant content. The result? Faster onboarding, smoother integrations, and fewer support tickets.

Scaling with Confidence: Built for the Enterprise

For enterprise merchants operating at scale, with large engineering teams, global operations, and high transaction volumes, automated SDKs offer a clear advantage. They enable rapid rollout across geographies and PSPs, provide version control that grows with your teams, and ensure alignment across development, QA, and compliance environments. This automation also shortens time-to-market for experiments and checkout updates, giving teams the agility they need to innovate. And because Gr4vy’s SDKs are auto-versioned using semantic versioning, any breaking changes are clearly communicated, putting you in full control of your upgrade cycles.

Developer Experience is a Growth Lever

Payments may be complex, but integrating them shouldn’t be. At Gr4vy, we’re investing in developer-first infrastructure because we know better developer experience = better business. Whether you’re an engineer building a localized checkout flow or a platform team managing dozens of PSPs, our SDK stack is designed to help you ship faster, with fewer errors, and more control.
