# Slack: configure a Redirect URL for OAuth — OAuth & Permissions → Redirect URLs

## Steps
1. Open App Management → select the app → "OAuth & Permissions".
2. Under Redirect URLs, add the URL Slack should redirect to after a user authorizes the app.
3. Save the change.

## End state
The URL is listed under Redirect URLs on the OAuth & Permissions page; the OAuth install flow now redirects there with the `code` parameter after authorization, instead of failing with a redirect-mismatch error.
