I am sending a `PUT` request to `http://localhost:3000/t/220.json` with `{"tags":["bug"]}` to update the tags on my topic with ID `220`.

I am getting Error 403  
`{"errors":["You are not permitted to view the requested resource."],"error_type":"invalid_access"}`.

Can someone tell me what I am doing wrong here?

Some endpoints require an authentication. You will need to pass an API user and key: [https://docs.discourse.org/](https://docs.discourse.org/)

I have taken care of authentication. Infact, I am able to add post on the same topic from API.

I don’t know then, but the url should be `/t/-/220.json ` if you don’t provide a slug.

Thanks, It worked. But can you elaborate what is a slug in terms?

Your SEO-friendly topic title in this case.  
This slug here is: `not-able-to-update-tags-using-api` (look tat the bar address)

By the way, this tip about `-` is actually from the documentation:
