Unary gRPC Calls

Learn about the unary call types in gRPC and how to implement them.

There are four call types supported by gRPC: unary, server-streaming, client-streaming, and bi-directional streaming calls. The most simple gRPC call is a unary call. This type of call accepts a single request message and returns a single response message. It can be used in any scenario where either a single object needs to be retrieved from the server or a single action needs to be triggered.
