MODULE 09 // DEVELOPER EXPERIENCE

API Documentation.

Create comprehensive documentation enabling effective integration.

DOCUMENTATION STRATEGY

Documentation determines API adoption. Developers evaluate APIs by trying them, and good docs reduce time-to-first-successful-call dramatically.

OpenAPI (Swagger) specification provides machine-readable API definition. Generate interactive documentation, client SDKs, and server stubs from single source of truth.

Include code examples in multiple languages. Show complete request/response cycles, not just endpoint definitions. Document error scenarios as thoroughly as success paths.

OPENAPI SPEC

Machine-readable API definition. Single source of truth for all documentation.

FOUNDATION

INTERACTIVE DOCS

Try-it-now functionality. Developers can test endpoints without writing code.

EXPLORATION

CODE EXAMPLES

Complete examples in major languages. Copy-paste to working integration.

IMPLEMENTATION

ERROR CATALOG

Document every error code with causes and solutions. Debug assistance.
