When a downlink message is sent to a device, an acknowledgement is generated by the Sigfox network.
The acknowledgement can be retrieved through callbacks by the customer.
Callback creation procedure
- Go to your device type and create a custom callback with Type "SERVICE / ACKNOWLEDGE", which includes "downlinkAck" as variable.
- Additionally, you can include "InfoCode" variable in the URL, which will provide you more information about the Downlink transmission.
You will find all InfoCode value explanation within the Backend callback documentation: https://backend.sigfox.com/apidocs/callback
