Issue token

You should generate the token in admin user, not owner. If you generate the token in owner user, a missing_scope error may occur.

There are two ways to issue the access token.

Legacy tokens

1. Visit https://api.slack.com/custom-integrations/legacy-tokens.

2. Click Create token.

   

OAuth tokens

1. Visit https://api.slack.com/apps and Create New App.

   

2. Click "Permissions".

   

3. In "OAuth & Permissions" page, select admin scope under "Permission Scopes" menu and save changes.

   

4. Click "Install App to Workspace".

   

5. Visit https://slack.com/oauth/authorize?&client_id=CLIENT_ID&team=TEAM_ID&install_redirect=install-on-team&scope=admin+client in your browser and authorize your app.

   • This form requires the client permission. Otherwise, you can see {"ok":false,"error":"missing_scope","needed":"client","provided":"admin"} error.
   • Your TEAM_ID is the subdomain for your slack team, e.g. myteam.slack.com - your TEAM_ID is myteam.
   • Your CLIENT_ID found in "Basic Information" section for your App.
   • You will be shown a Installed App Settings > OAuth Tokens for Your Team screen.
   • You can test auto invites with curl by providing the OAuth Access Token.

   curl -X POST 'https://myteam.slack.com/api/users.admin.invite' \
   --data 'email=test@email.com&token=OAuthAccessToken&set_active=true' \
