The gRPC protocol (https://grpc.io/) is used to support the transport layer between the Axxon Next services. 

The gRPC API allows to simplify the large-scale systems configuration.

The gRPC protocol uses special proto-files to generate the code base.

The proto-files contain some strict syntax that defines the interface for the various program modules interaction.

To obtain the Axxon Next proto-files and their use-cases, contact the technical support service.

You can call gRPC API methods using a POST request (see gRPC API method calls).
