This feature is available on Postman Team and Enterprise plans. For more information, see the pricing page.

Postman SDK Generator transforms your Postman Collections into client SDKs for nine programming languages. Generate type-safe client libraries with automatic method generation, intelligent type inference, and comprehensive documentation directly from your API specifications.

The generator preserves custom code across regenerations using intelligent change tracking and three-way merge conflict resolution. Add validation logic, custom transformations, and business rules to your SDKs while maintaining those customizations when you update the underlying API specification. Configure language-specific settings, integrate with build tools, and distribute SDKs across your organization with consistent branding and authentication patterns.

Supported languages

Generate SDKs for these programming languages:

  • TypeScript — Modern web and Node.js applications
  • Python — Data science, automation, and backend services
  • Java — Enterprise applications and Android development
  • Kotlin — Android development and JVM applications
  • C# — .NET applications and enterprise systems
  • Go — Cloud services and microservices
  • PHP — Web applications and APIs
  • Ruby — Web development and scripting
  • Rust — System programming and performance-critical applications

Common use cases

You can use the Postman SDK Generator for a wide range of scenarios, from internal team consumption to public API distribution. Here are some common use cases.

API client libraries

Generate type-safe client libraries that provide method calls for your API endpoints. They’re perfect for the following scenarios:

  • Internal team consumption
  • Partner integration
  • Public API distribution
  • Mobile app backends

Custom business logic

Add validation, transformation, and business rules to generated SDKs. They’re ideal for the following scenarios:

  • Input validation and sanitization
  • Response data transformation
  • Custom authentication flows
  • Audit logging and analytics
  • Error handling and retry logic

Enterprise distribution

Package and distribute SDKs across your organization:

  • Consistent API access patterns
  • Centralized authentication
  • Corporate branding and documentation
  • Version management and updates

Key features

The SDK Generator automatically transforms your API specifications into working code with the following features:

  • Automatic type inference from API schemas
  • Method generation from collection requests
  • Documentation generation from descriptions
  • Example code from request samples

Your customizations stay safe when you regenerate SDKs because you’re able to do the following:

  • Preserve custom code across regenerations
  • Three-way merge conflict resolution
  • File-level change detection
  • Selective customization uploads

Adapt SDK generation to fit your development workflow using the following strategies:

  • Language-specific settings and overrides
  • Custom code integration options
  • Build tool integration
  • Package management configuration
