Add alert channel support for Pushover

We don’t currently provide a native Pushover alert channel, but you can connect Pushover using Checkly’s customizable webhook channel:

1. In Pushover, register an application and copy its API token and your user or group key.

2. Store those values as Checkly secrets named PUSHOVER_API_TOKEN and PUSHOVER_USER_KEY.

3. In Checkly, open Alerts → Alert channels → New alert channel → Webhook.

4. Configure:

   • Method: POST

   • URL: https://api.pushover.net/1/messages.json

   • Header: Content-Type: application/json

   • Body:

{
  "token": "{{PUSHOVER_API_TOKEN}}",
  "user": "{{PUSHOVER_USER_KEY}}",
  "title": "{{ALERT_TITLE}}",
  "message": "{{ALERT_TYPE}}\n{{CHECK_NAME}}\n{{STARTED_AT}} ({{RESPONSE_TIME}} ms)",
  "url": "{{RESULT_LINK}}",
  "url_title": "Open in Checkly",
  "priority": 0
}

5. Use Send test, save the channel, and subscribe it to the relevant checks or groups.

See Checkly’s webhook alert documentation for the available alert variables.
