Look for the Webhooks service at the end of the page (services are alphabetically ordered), click on it, and click on the Documentation button. A new page will show the key in a legend like this: Your key is: cjodX8trC3YXPLMrESXb-Y.

  • Additionally, every time the sensor detects movement (and the LED light-up), IFTTT triggers the webhook, and the notification appears on the smartphone:
