OpenAPI (Swagger) - SDK documentation and generation

OpenAPI (Swagger) - SDK documentation and generation
For fast and easy API integration, you need structured documentation. 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This lowers the entry threshold for developers, speeds integration, and eliminates errors associated with incomplete or outdated interface descriptions.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 OpenAPI/Swagger gives

OpportunityBenefits
Interactive documentationSwagger UI with the ability to test APIs right in the browser
SDK generationAutomatic creation of client libraries in different languages
Structure by standardDescription of all endpoints, parameters, answers, errors and authorization
Machine readabilityAPI can be validated, parsed, exported and connected to CI/CD
CurrentDocumentation updates 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.
