API source

You can always find the source of the latest ZBOS API as well as older versions in the ZBOS MQTT API git repository.

These JSON files are in AsyncAPI format, which you can use to generate documentation or code for use in your own application (see: AsyncAPI Generator).

The zbos_mqtt-all-asyncapi.json contains the complete API, while the other files contain specific parts, so you can be selective and only use the parts you need in your App.
