Slack Oauth/Authorize API Call

Question

I\'m new to OAuth (and the Slack API) and have a question regarding Step 1 of Slack\'s OAuth Flow.

It says \"Your web or mobile app should redirect users to the followin

Answer 1

You should check out the Slack button docs.

There you will find an example for your slackapp, something like:

<a href="https://slack.com/oauth/authorize?scope=incoming-webhook&client_id=CLIENT_ID">
   <img alt="Add to Slack" height="40" width="139" 
   src="https://platform.slack-edge.com/img/add_to_slack.png" />
</a>

This button asks for authorization for a slackapp that includes incoming webhooks, you can add more features needed inside scope separating them by commas. scope=incoming-webhook,commands,bot,channels:read

As of your tutorial link, when it says you should link them to https://oauth2server.com/auth?response_type=code&client_id=CLIENT_ID&redirect_uri=REDIRECT_URI&scope=photos

It is refering to wrap that into a button for the user:

<a href="https://oauth2server.com/auth?response_type=code&client_id=CLIENT_ID&redirect_uri=REDIRECT_URI&scope=photos">
   Auth Button
</a>

Hope this helps clarify the usage of /oauth/authorize
