I am working on [this forum](https://discourse.joplinapp.org/) which is powered by Discourse. After the moderators provided me with an api key and username, I found a bug in the `POST /posts.json` API endpoint.

As mentioned [here](https://docs.discourse.org/#tag/Posts/paths/~1posts.json/post) this endpoint accepts a `topic_id` which should be an **integer**. But when I make a request using the `topic_id` and `raw` parameters something like

```json
{
  "topic_id": 17470,
  "raw": "Test post."
}

```

I get the following error.

```plaintext
'You are not permitted to view the requested resource. The API username or key is invalid.'

```

But I am successfully able to create the post after changing the request data such that `topic_id` is a string.

```plaintext
  "topic_id": "17470",
  "raw": "Test post."
}

```

Something does not sound right, from the perspective of an HTTP POST there is no difference between `100` and `"100"`.

Can you provide with a consistent repro here?
