Mailgun


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 integration (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.

There is currently support for the following device types within Home Assistant:

Configuration

# Example configuration.yaml entry
mailgun:
  domain: EXAMPLE.COM
  api_key: YOUR_API_KEY

Configuration Variables

domain

(string)(Required)

This is the domain name to be used when sending out mail. Needs to be the first custom domain you have set up.

api_key

(string)(Required)

This is the API token that has been generated in your Mailgun account.

sandbox

(boolean)(Optional)

(Deprecated) Whether to use the sandboxed domain for outgoing mail. Since the domain item is required, it should be set to the sandbox domain name, so this isn’t needed.

Default value:

false

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
