In system integration, different interaction patterns are used depending on the communication requirements between systems. For a synchronous invocation of a RESTful API using HTTP to get an individual customer record from a single system, the Request-Reply pattern is used. Here's a detailed explanation:
* Request-Reply Pattern:
* Definition: This pattern involves a client sending a request to a server and waiting for a reply.
The communication is synchronous, meaning the client waits for the server to process the request and send back the response.
* Typical Use Case: It is used when immediate feedback is required from the server, such as retrieving a specific customer record.
* RESTful API and HTTP:
* Synchronous Communication: HTTP is inherently synchronous, making it suitable for Request- Reply interactions where the client expects an immediate response.
* Data Retrieval: Commonly used for GET requests in RESTful APIs to retrieve data from a server.
* Example:
* Scenario: A client application requests customer details by making a GET request to a RESTful API endpoint. The server processes the request and returns the customer record.
