Connexion is a framework on top of Flask that automagically handles HTTP requests defined using OpenAPI (formerly known as Swagger), supporting both v2.0 and v3.0 of the specification. Connexion allows you to write these specifications, then maps the endpoints to your Python functions. This is what makes it unique from other tools that generate the specification based on your Python code. You are free to describe your REST API with as much detail as you want and then Connexion guarantees that it will work as you specified. We built Connexion this way in order to simplify the development process. Reduce misinterpretation about what an API is going to look like. With Connexion, you write the spec first. Connexion then calls your Python code, handling the mapping from the specification to the code. This incentivizes you to write the specification so that all of your developers can understand what your API does, even before you write a single line of code.
Features
- If multiple teams depend on your APIs, you can use Connexion to easily send them the documentation of your API
- Handles OAuth 2 token-based authentication
- Validates requests and endpoint parameters automatically, based on your specification
- Provides a Web Swagger Console UI so that the users of your API can have live documentation and even call your API's endpoints through it
- Supports automatic serialization of payloads
- If your specification defines that an endpoint returns JSON, Connexion will automatically serialize the return value for you and set the right content type in the HTTP header
