To be able to receive webhooks from Mailgun, your Home Assistant instance needs to be accessible from the web and you need to have the extern URL [configured](/docs/configuration/basic)).
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:
- [Notifications](#notifications).
## Configuration
```yaml
# Example configuration.yaml entry
mailgun:
domain: EXAMPLE.COM
api_key: YOUR_API_KEY
```
{% configuration %}
domain:
description: This is the domain name to be used when sending out mail. Needs to be the first custom domain you have set up.
required: true
type: string
api_key:
description: This is the API token that has been generated in your Mailgun account.
required: true
type: string
sandbox:
description: "(**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."
required: false
default: false
type: boolean
{% endconfiguration %}
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](https://documentation.mailgun.com/en/latest/api-events.html#event-structure) 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:
```yaml
automation:
trigger:
platform: event
event_type: mailgun_message_received
event_data:
action: call_service
action:
service: light.turn_on
entity_id: light.office
```
## Notifications
The Mailgun notification service allows you to send emails via Mailgun's REST API. It requires the [Mailgun component](#configuration) to be set up.
### Notifications configuration
```yaml
# Example configuration.yaml entry
notify:
- name: mailgun
platform: mailgun
recipient: CHANGE@EXAMPLE.COM
```
{% configuration %}
domain:
description: This is the domain name to be used when sending out mail.
required: true
type: string
sandbox:
description: "(**Deprecated**) If a sandboxed domain is used, specify it in `domain`."
required: false
default: false
type: boolean
api_key:
description: This is the API Key that has been generated in your Mailgun account.
required: true
type: string
recipient:
description: The email address of the recipient.
required: true
type: string
sender:
description: The sender's email address.
required: false
default: "`hass@DOMAIN`, where `DOMAIN` is the outgoing mail domain, as defined by the `domain` configuration entry."
type: string
{% endconfiguration %}
### Example automation
The following automation reacts to an event by sending out an email with two attachments.
```yaml
# Example automation using Mailgun notifications
automation:
trigger:
platform: event
event_type: SPECIAL_EVENT
action:
service: notify.mailgun
data:
title: "Something special has happened"
message: "This a test message from Home Assistant"
data:
images:
- /home/pi/pic_test1.png
- /home/pi/pic_test2.png
```
