Hi, Eric. The wildcard should work for this, as it would be in the subdomain portion of the URL. Should this not give the desired outcome, you can also click on the Add URI button and add additional sign-in redirect URIs and sign-out redirect URIs as needed. Please let me know if you have any further questions or issues.
You can add multiple static sign-in redirect URIs.
There can be only a single initiate login URI and this will use the very first sign-in redirect URI you have listed when doing an IdP initiated login flow.
There can only be a single initiate login URL and it can’t contain wild cards as there is no way to know what to substitute for wildcard values in an IdP initiated flow.
