Case Study
API Documentation & Developer Experience
OpenAPI, Swagger, Postman, and Apidog as part of shipping APIs people can actually use.
- OpenAPI
- Swagger
- Postman
- Apidog
Problem
APIs without clear contracts are slow to adopt and easy to misuse.
Context
API platforms and integrations where schemas, auth docs, and testing tools matter.
Challenge
Keeping docs aligned with real behavior while supporting auth flows and practical testing.
Approach
I used OpenAPI/Swagger-style docs plus Postman and Apidog to describe, test, and communicate the contract.
Result
Treated docs and developer experience as part of shipping the API, not a later cleanup task.
Lessons
An API only works if other developers can understand and trust the contract.
