Hello. I want to customize the payload value of webbook when an event for topic generation occurs. Example… AS-IS { "post": { "id": 19, "name": "user", "username": "user", "avatar_template": "/letter_avatar_proxy/v2/letter/u/c0e974/{size}.png", "created_at": "2018-07-20T06:24:33.205Z", "cooked": " Cool, now i have you, haha ", "post_number": 6, "post_type": 1, "updated_at": "2018-07-20T06:24:33.205Z", "reply_count": 0, "reply_to_post_number": null, "quote_count": 0, "avg_time": null, "incoming_link_count": 0, "reads": 0, "score": 0, "topic_id": 11, "topic_slug": "this-is-new-topic", "topic_title": "This is new topic", "display_username": "user", "primary_group_name": null, "version": 1, "user_title": null, "moderator": false, "admin": true, "staff": true, "user_id": 1, "hidden": false, "trust_level": 1, "deleted_at": null, "user_deleted": false, "edit_reason": null, "wiki": false, "topic_posts_count": 6 } } TO-BE { "topic_title": "This is new topic" } Can I know how to do it?

我也有类似的需求。也感到困惑。目前没有什么好办法。

Hey, there’s no built-in way in Discourse to send only a tiny part of the webhook payload, but a couple of ideas that might work: - You could have a small proxy in the middle (like a tiny Node.js or Python endpoint) that gets the full webhook, strips everything except `topic_title`, then forwards it on. Super flexible and doesn’t touch Discourse itself. - Or, if you’re up for it, a tiny Discourse plugin could listen to `on(:post_created)` and send only the fields you care about. Just a few lines in Ruby and you’re done. - Another lazy option is to just let a tool like Zapier or n8n grab the full payload and map/filter it before it reaches your final system. Nothing fancy, just some ways I’d play around if I needed only `topic_title` :slightly_smiling_face:

是的。我使用的是第1种，但是这需要额外的编码和维护。

Yes. I am using the first one, but this requires extra coding and maintenance.
