docker-apprise-webhook

Webhook receiver for Apprise

Allows to receive JSON messages and send them to Apprise API using a custom template.

Requirements

• Installed Apprise API

• A template for converting a message from webhook. Templates are using nunjucks templating engine. Built-in templates:

  • template - template name which should be used (excluding .njk)
  • key - key to append to Apprise URL (e.g. http://apprise:8000/notify/key)
  • title - title to pass to Apprise API
  • type - type to pass to Apprise API
  • tag - tag to pass to Apprise API

• Environment variables
