// Create a new Command with a simple message to send: message := &model.Command{ Command: "/hello", ChannelId: "ABCDE12345", TeamId: "FGHIJ67890", UserId: "USER123", Text: "Hello, world!", } // Send the Command to the Mattermost server: response, err := client.ExecuteCommand(message) // Parse the response (if any): if response != nil { println(response.Text) }This code creates a new Command with a simple message to send to the server, and then sends the Command using a client provided by the Mattermost API. The response from the server is then parsed and the text is printed out. There are many other methods and options available for working with Commands in the Mattermost API. This package provides a convenient way to work with these features from within Go programs.
