Cellular measurement webhook

Organizations with the Cellular API add-on can receive a JSON POST every time a device sends measurements, without polling.

Set up

1. Open Integrations and find the Cellular API webhook section.
2. Enter your HTTPS endpoint URL.
3. Optionally set a secret to receive an HMAC signature with each request.

The payload contains the device serial number and its measurement channels. Respond with a 2xx status code to acknowledge delivery. Use the REST API to fetch history if your endpoint was unavailable.
