slack api rtm.start missing_scope needed client

Question

I have get access token and when I try to post rtm.start, I am getting below error:

{
    error = "missing_scope";
    needed = client;
    ok = 0;
    provided = "identify,read,post";
}

I have set the scope to read,post,identify in authorize API. I have read the API document over and over again. Only rtm.start mentioned client scope. But in oauth document I didn't find a client scope. So, what's wrong?

You have to do it before you get the token.

when you do the initial request to connect the app, include &scope="identify,read,post,client"

I read the docs, and the client is not in the scope. It worked. Thanks . – yong ho Jan 30 '15 at 11:03

If you print the body of the response, it will tell you what scope is missing: e.g. `{"ok":false,"error":"missing_scope","needed":"users:read","provided":"identify,team:read"}` – John Difool Apr 10 '16 at 01:08

@hailgrail I can't find client in the Scopes section of creating a new app. Any idea? – user3248578 Sep 04 '17 at 04:42

Under App Credentials get your Client ID and Client Secret. Goto:

https://#{team}.slack.com/oauth/authorize?client_id=#{cid}&scope=client

replacing #{team} and #{cid} with your values.

When you approve the authorization you’ll goto that real url that doesn’t resolve. Copy the whole url to your clipboard and paste it into a text file. Extract out just the “code” part.

Now goto:

https://#{team}.slack.com/api/oauth.access?client_id=#{cid}&client_secret=#{cs}&code=#{code}"

And you’ll get back a token like: xoxp-4422442222–3111111111–11111111118–11aeea211e
