To be able to receive webhooks from Mailgun, your Home Assistant instance needs to be accessible from the web ( instructions) and you need to have the base_url configured for the HTTP component (docs).

To set it up, go to the integrations page in the configuration screen and find Mailgun. Click on configure. Follow the instructions on the screen to configure Mailgun.

You will get a URL of the following format: https://<home-assistant-domain>/api/webhook/9940e99a26fae4dcf6fe0a478124b6b58b578ea4c55c9a584beb1c9f5057bb91. To receive webhooks from Mailgun, you need to provide that url as a callback URL in the Webhooks tab of the Mailgun Control Panel.

Events coming in from Mailgun will be available as events in Home Assistant and are fired as mailgun_message_received. The data specified by Mailgun will be available as the event data. You can use this event to trigger automations.

You can then consume that information with the following automation:

    platform: event
    event_type: mailgun_message_received
      action: call_service
    service: light.turn_on

To send messages, use the Mailgun notify platform.
