# LINE webhook
This guide describes how to integrate your Zabbix installation with LINE messenger using Zabbix webhook feature. It also provides instructions on setting up a media type, a user and an action in Zabbix.
## In LINE developer console
1. Create a messaging `channel access token` following original instructions on [How to use the messaging API](https://developers.line.biz/en/docs/messaging-api/overview/).
2. Copy the `channel access token` of your new integration to be used in Zabbix.
## In Zabbix
The configuration consists of a _Media type_ in Zabbix, which will invoke the webhook to send alerts to LINE messenger through the LINE messaging API.
1. Create a global macro `{$ZABBIX.URL}` following these instructions in [Zabbix documentation](https://www.zabbix.com/documentation/7.0/manual/config/macros/user_macros) with Zabbix frontend URL - for example, `http://192.168.7.123:8081`.

2. Import LINE media type from this file [media_line.yaml](media_line.yaml) following these instructions in [Zabbix documentation](https://www.zabbix.com/documentation/7.0/manual/web_interface/frontend_sections/administration/mediatypes).

3. Change the value of the variable `bot_token` to the `channel access token`.
For more information on Zabbix webhook configuration, see [Zabbix documentation](https://www.zabbix.com/documentation/7.0/manual/config/notifications/media/webhook).
4. Set _Media type_ `LINE` for each user you would like to get notified and fill _Send to_ field with the corresponding ID of the target recipient. Use a `userId`, `groupId`, or `roomId` value. See [Common properties in webhook event objects](https://developers.line.biz/en/reference/messaging-api/#common-properties) for more information.
See more details on creating [Zabbix user](https://www.zabbix.com/documentation/7.0/manual/web_interface/frontend_sections/users/user_list).
LINE user should suffice the default settings as this user will not be logging into Zabbix. Note that in order to be notified about problems on a host, this user must have at least read permissions for this host.
When configuring an alert action, add this user in the _Send to users_ field (in _Operation_ details) - this will tell Zabbix to use LINE webhook when sending notifications from this action.
Use the LINE user in any actions of your choice.
### Testing
Media testing can be done manually, from `Media types` page. Press `Test` button opposite to the previously defined media type, under _Actions_.
1. To create a problem, following fields should be set:
* `alert_message` = Test message
* `alert_subject` = Test subject
* `bot_token` = `Channel access token`
* `event_id` = 1234567890
* `event_nseverity` = 5
* `event_source` = 0 (it simulates trigger based event)
* `event_update_status` = 0 (not an update operation)
* `event_value` = 1 (this is a problem event)
* `send_to` = `ID of the recipient`
* `trigger_description` = Test trigger description
* `trigger_id` = 0987654
* `zabbix_url` = https://127.0.0.1

2. Having successfully sent a message from Zabbix, check if it has been received by the recipient.
