Setup in the Slack dashboard

1. Go to the Slack API dashboard.
2. Create a new app (or open an existing one).
3. In OAuth & Permissions, add a redirect URL (the URL Slack sends users back to after login).
   • Use the full URL of the page you select as Success page in WeWeb.
4. Copy the credentials Slack provides (for example Client ID and Client Secret).

2. Select Slack and turn on the Enable toggle.
3. Paste your credentials into the fields shown in WeWeb.
4. Click Save.

Test sign in

2. Create a workflow on click and add Sign in with social provider.
3. Set:
   • Provider: slack
   • Success page, Error page, And (optional) New user page

Common pitfalls

Make sure the redirect URL in Slack exactly matches the Success page URL you selected in WeWeb.
