How to revoke a slack token?

I know about the slack API auth.revoke, but when I use it, it doesn't work.

I am trying the following by inputting it in my terminal, where <TOKEN> is the slack token.

curl -i https://slack.com/api/auth.revoke H "Authorization: Bearer <TOKEN>"

The error that I am getting is:

{"ok":false,"error":"not_authed"}curl: (6) Could not resolve host: H
curl: (3) Port number ended with ' '

I am expecting to see, {"ok":true,"revoked":true}

Solution

You get this response because you technically did not provide a token to the API method. Providing tokens in an authorization header only works with methods that support a POST body in JSON. auth.revoke does not support that as it's stated in the official documentation:

Present arguments as parameters in application/x-www-form-urlencoded querystring or POST body. This method does not currently accept application/json.

Here is the correct syntax with curl:

curl https://slack.com/api/auth.revoke -X POST --data "token=TOKEN"
