For an API to be developer-friendly, it must be clear, accessible for testing, and well documented. We connect and configure Swagger UI, Postman and Insomnia - the three most popular tools that allow you to quickly test APIs, understand the structure of requests and facilitate the integration process for both internal teams and external partners.


Why these tools are needed

ToolAppointment
Swagger UIAutogeneration of the OpenAPI Specification Online Documentation
PostmanManual and automated testing of queries, collections, scripts
InsomniaEasy debugging, working with variables, tokens, GraphQL, REST and gRPC

Opportunities we are pursuing

Generating OpenAPI (Swagger) specifications from code

Swagger UI

Import collections into Postman/Insomnia with examples of all endpoints

Working with OAuth2, JWT, API keys in tools

Synchronize tests and documentation with CI/CD pipeline

Publish collections to external partners


Benefits for team and customers

Fast onboarding of new developers

Faster integration by external teams

Single source of truth on API structure

Simplified testing and debugging at any stage

Reduce partner questions and integration errors


Where especially important

Open API or SDK platforms

Internal microservices with frequent changes

API-first products and B2B services

Any projects with high speed of development and change of teams


Swagger UI, Postman and Insomnia are must-have tools for modern API development. We will connect and configure them so that your APIs are transparent, testable and easy to use both within the team and for partners.
