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.
`PUT /t/:slug/:id` doesn’t seem to be what I’m looking for.
Any advice here, please?

The [official docs](http://docs.discourse.org/#tag/Posts%2Fpaths%2F~1posts~1%7Bid%7D%2Fput) say it’s a `PUT` for `/posts/:id` with `post[raw]` in FormData:

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.

Got it. [Discourse API Docs](http://docs.discourse.org/#tag/Topics%2Fpaths%2F~1t~1%7Bid%7D.json%2Fget)

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).
