Lemmy Webhook - add webhook support to your Lemmy instance

cross-posted from: lemmings.world/post/4527175

Note that unless you’re a Lemmy instance admin, this doesn’t have much use to you.

Until this package came along, if you wanted a bot that responds to events, you had to manually traverse all comments/posts/whatever at a fixed interval. With this package you can actually react to events directly from the database. It’s implemented in a very efficient way by connecting the package directly to the Lemmy database and using native Postgres features to get the events (LISTEN/NOTIFY if you want to get technical).

The webhooks themselves are inserted into a separate SQLite database (API is coming) and allow for both simple and complex filtering of the incoming data. The system is already in use by two of my bots, @ChatGPT and @DallE who now both receive the information about being tagged in a comment in seconds (the actual reply takes a little longer, but that’s because of the nature of the bot).

Currently you can be notified about a post or a comment, other types are trivial to include as well.

Let me know what you think!
