Reverse API Proxy

What is a Reverse proxy?

• It receives the request from the client, processes it, and calls the backend service to get the data that the client requests.

• Send the response back to the client.

Scenario: The client sends a request message to the backend service to get the employee information according to its ID.

Apigee Implementation: Create a reverse API Proxy by using the backend service URL(target endpoint)
target endpoint: https://jsonplaceholder.typicode.com/users
Run the above endpoint in Postman by adding id:1 in the parameter below and see the output.

• We successfully created the Reverse proxy with the target endpoint (https://jsonplaceholder.typicode.com/users?id=1).

• The client sent a request message including id: 1 in the query parameter to the API proxy. Then proxy hits the target(Backend service) and gets the data as requested by the client. And respond to the client with a response message.
