End-user guide to authorize the integration and start using Slack actions. This token acts as the user who installs the app. Leave token rotation turned off — this authentication method has no refresh flow, so a rotating token stops working within 12 hours.

Scroll to the top of the OAuth & Permissions page. Under Advanced token security via token rotation, the Opt In button must still be shown. Don't click it.

Slack returns to OAuth & Permissions. Under OAuth Tokens, click Copy next to User OAuth Token and paste it into the User OAuth Token field in StackOne Hub.

  • Format: `xoxp-...` — a token that starts with `xoxe.` means token rotation is on and won't work here
  • Treat the token like a password and store it securely. Anyone who has it can call Slack as you.
  • If you add or change scopes later, click Reinstall to followed by your workspace name, then copy the new token.

Linking the Account from the Hub

Use one of the three Linking Account Methods to access the Hub. Fill out the following fields using details from your provider:
  • User OAuth Token
  • Click Connect
  • If applicable, the provider will redirect you to a sign-in or authorization page. Complete the provider's authorization flow.
  • Once authorization is successful, you will see a confirmation popup

If the account linking is successful, you will see the newly linked account in your Accounts page.
