The gRPC protocol is used to support the transport layer between Axxon One 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 interaction interface of the various program modules.

To get Axxon One proto-files, contact the technical support service.

Examples of gRPC API methods.

You can call the gRPC API methods using the HTTPS or HTTP requests (see gRPC API method calls) or through direct gRPC requests (see Working with Axxon One via direct gRPC requests).

To call the methods using the HTTPS requests, you should use the SSL certificate (see Configuring the Web-Server) or disable the SSL verification on the side of the message sender.
