6. What is Proxy API and How to implement Proxy Service
Mule 4 Proxy API Implementation

7. 7
● What is Proxy API?
○ Proxy API is nothing, but an API develop on top of other APIs.
○ With a proxy API, the application continues to run without issue and continue to call and connect to
the backend API while a developer is editing it.
○ Exposing a proxy API also protects the backend API from the world, shielding the real IP address.
● Requirement
○ If we want to hide our backed API's complexity from client
○ If we don't want our client to update their API configurations frequently due to our API endpoint
changes.
○ If we don’t want to repeat the cycle(DEV-UAT-PROD) of Deployment for Client API due to new
changes in our backend.
