Understanding service call out

I am trying to understand service call out policy.

My understanding is I get values from target backend and from service call out url and get both together in the client.

My issue I take Vinod from target backend ,Mehta from service call out url and get Vinod Mehta together in the client.

Am i correct?

Can anybody explain a use case for the same?

A service callout is for calling another service from a flow in your Apigee API Proxy.

A mashup of responses is one use case for a service callout. Another is if the second call was dependent on the first call ie you're using data from the response in the subsequent call.

Thank you..
