To be able to receive webhooks from Mailgun, your Home Assistant instance needs to be accessible from the web (Hass.io 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:
automation: trigger: platform: event event_type: mailgun_message_received event_data: action: call_service action: service: light.turn_on entity_id: light.office
To send messages, use the Mailgun notify platform.
