Explainer

An API proxy acts as a secure intermediary between external clients and a backend API implementation. By sitting in front of the implementation, it enforces management policies like security and rate limiting without requiring any changes to the underlying backend code. This separates the public API interface from the internal implementation, allowing teams to update or replace the backend without disrupting consumers.

Core information
  • An API client (consumer) initiates an API invocation by sending a request to the proxy's public endpoint, which serves as the stable API interface for external consumers.
More details and nuances
  • If any configured policy fails validation, the proxy immediately returns an error response to the client and blocks the request from ever reaching the backend implementation.
