Add a redirect URI
After you register your application on the ArcGIS Developer dashboard, you can add a redirect URI to that application. This is the redirect URL to which a user is sent once they complete sign in authorization.
To add a redirect URI to an existing application:
From the ArcGIS Developer dashboard, OAuth 2.0 tab, select an application and click View Full Credentials.
Scroll down to the Redirect URLs tile.
Click + Add URI and enter the address in the format
http://my-arcgis-app:/auth. This is a valid web page or server endpoint to which a user can be redirected after successful sign in.
Click Add URI.
The redirect URL will be listed on the Redirect URLs tile.
To remove a redirect URL, click Ø next to the URL. You will be asked to confirm your deletion.
To edit a redirect URL, click the pencil icon and then update the address / endpoint. Click Edit URI to save your changes.
