This causes the trigger service to send a Meshblu message to the flow to tell it to trigger. If no authentication information is passed, it will send the message as the identity of the Trigger Service.

Additionally, any POST data sent will be made available to the flow.

❗️

Breaking changes to the V1 API

Unlike the V1 API , the V2 API does not wrap the POST body in msg.payload nor msg.params in the designer. Instead, the post body will be available on the msg.data object. Metadata about the request can be accessed on msg.metadata.

🚧

Check the Permissions

In order to activate the trigger, the trigger service's UUID must be in the flow's message.from whitelist. Generally, the Octoblu Designer will manage the Whitelist for the user. See the Meshblu whitelist documentation for more information.
