Structured documentation is required for fast and easy API integration. We use the OpenAPI 3 specification. 0 + (formerly Swagger), which allows you to describe all API methods, parameters and models in a single standardized format, with the ability to generate code, test and export the SDK.
This lowers the entry threshold for developers, speeds integration, and eliminates errors associated with incomplete or outdated interface descriptions.
What does OpenAPI/Swagger give
| Opportunity | Advantages |
|---|---|
| Online documentation | Swagger UI with the ability to test APIs right in the browser |
| SDK generation | Automatic creation of client libraries in different languages |
| Structure by standard | Description of all endpoints, parameters, responses, errors and authorization |
| Machine readability | APIs can be validated, parsed, exported and connected to CI/CD |
| Relevance | Documentation is updated automatically when API changes |
How it is implemented
API description in OpenAPI 3 format. 0 (.yaml or. json)
Ability to generate Postman collections and SDKs (cURL, JS, PHP, Python, Java, Go)- Authorization support: API key, JWT, OAuth2
- Visually display available queries and possible responses
- API testing directly from documentation (Swagger UI/Redoc)
Developer Benefits
Quick connection without manual parsing of the structure- IDE and code generator support (Swagger Codegen, OpenAPI Generator)
- Documentation always matches current API
- Convenient for transfer to partners and integrators
- Improved DX (developer experience) and implementation speed
Where especially important
Open or Public API Projects- Teams practicing API-first approach
- Platforms with external integrations and partner connections
- Mobile and front-end applications that work with the backend API
OpenAPI is a modern API description language, and Swagger is its user-friendly interface. You get transparent documentation, fast SDK generation and maximum convenience for everyone who connects to your system.
