  2. Configure Redirect URLs
    • Open OAuth & Permissions from the left sidebar
    • Scroll to Redirect URLs and click Add New Redirect URL
    • Add your application’s OAuth callback URL
    • Click Add, then Save URLs
  3. Add OAuth Scopes
    • In the same OAuth & Permissions section, scroll to Scopes
    • Add scopes under Bot Token Scopes (app-level access) or User Token Scopes (user-level actions)
    • Common scopes:
      • channels:history — Read channel messages
      • chat:write — Send messages
      • users:read — Read user info
      • channels:read — Read channel list
      • files:read / files:write — File access
