The business logic of the client application blocks until it receives the response, and the communication channel has to be kept open until the client application receives the response. In the request-response pattern, one service (which acts as the client) sends a request and waits for a response from one or more other microservices or systems. ![]() You can think of REST API, and GraphQL is an implementation of the request-response pattern.

In this article, we’ll closely look at two separate popular technologies, REST API and GraphQL, which are a type of synchronous communication patterns.
