The following API

...

calls are available for the MQTT

...

Engine Module and can be executed within any of the

...

available Ignition scopes.

There are sample API scripts available for each API call.

Warning

Configuration changes made through scripting do not have the same validation as when made through the UI.

For example, deleting a Sets configuring that is being referenced by a Servers configuration will result in the UI showing an Internal Error. Follow the instructions here to recover the configuration.
