I’m trying to update a topic body via the API, but I’m not sure how to do it. I tried to use POST /posts/ and providing it with the topic_id which only creates a new post for a topic. I also tried PUT /posts/:id but providing it with the topic id doesn’t update the topic. I actually get a 403. PU…

Where :id is equal to the topic ID in this case?

No, it’s the post id. On Discourse land, a topic it’s just a bunch of posts. A topic has no body, the first post of the topic is the body.

It really depends on how you are managing stuff. If it’s a sync, you can save the post id of the topic when you create it, so it’s easy when you need to update it later (if that’s a common operation).

The official docs say it’s a PUT for /posts/:id with post[raw] in FormData:
