Sending Messages

Messages are sent via MQTT Topics. By defualt, there are 4 topic types supported:

  • Device
  • Store
  • Role
  • Group

To post messages / notifications to a Topic, BlueFletch Enterprise supports two methods:

  • BlueFletch Portal
  • Rest API

BlueFletch Portal

By using the BlueFletch Portal, an Admin can send messages to a specific topic. Simply log into the Portal and navigate to the 'Enterprise Launcher' tab, then 'Notifications'.


Enter the desired topic and json object of the message, then press send. See Notification Body for the format of the JSON Object.

Rest API

Posting a JSON object to the 'Notify' endpoint will send messages to the Topic.


Parameters : topic a string representing the Topic to post the message.

Header : x-bf-pb-apikey the organization's API Key

Body : the Json object representing the message to send. See Notification Body for the format of the JSON Object.
