A synchronous invocation of a RESTful API using HTTP to get an individual customer record from a single system exemplifies the request-reply interaction pattern. In this pattern, a client sends a request to a service and waits for a response. The interaction is synchronous because the client expects an immediate reply and is blocked until it receives the response.

This pattern is common in scenarios where the client needs to retrieve specific data or perform an action that requires immediate feedback from the server, such as retrieving a customer record from a database.
