    :alt: Diagram - Proxy pattern using Buildly

You can use Buildly's **API gateway** to implement a proxy pattern in your microservice architecture. Add all your services to Buildly via the API and it will run an auto-discovery process to identify all of the endpoints and combine them into a single API. All requests to and from the logic modules will be routed through Buildly. Authentication is handled with a `JSON Web Token (JWT) <https://jwt.io>`_.

All you need to do to use the API gateway with your logic modules is to ensure that they expose a `Swagger file <https://swagger.io/docs/specification/about/>`_ (`swagger.json`) at the `/docs` endpoint.
