Backend & API Technologies
Swagger
Swagger is an API documentation and development framework built around the OpenAPI Specification. It enables teams to design, document, test, and consume RESTful APIs with clear, machine-readable contracts.
What is it?
Swagger is a set of tools that implement the OpenAPI Specification (formerly known as Swagger Specification). It provides a standardized way to describe REST APIs so they can be easily understood by humans and machines.
What does it do?
Swagger allows teams to define API endpoints, request/response schemas, authentication methods, and error models. Tools like Swagger UI and Swagger Editor enable interactive documentation, testing, and client/server code generation.
Where is it used?
Swagger is widely used in backend APIs, microservices, enterprise systems, public developer platforms, and SaaS products where clear API contracts and strong developer experience are essential.
When & why it emerged
Swagger was introduced around 2011 to solve inconsistencies in API documentation. It evolved into the OpenAPI Specification, becoming the industry standard for API description and contract-first development.
Why we use it at Internative
We use Swagger/OpenAPI to design and document APIs with clear, versioned contracts. It improves collaboration between frontend and backend teams, accelerates integrations, and reduces ambiguity in API development.
