Using Single sign on (SSO) via JSON web tokens

Hello

I'm updating a custom application to take advantage of using the SSO via Json web tokens as outlined here:

I've setup a landing page so it calls the following url: https://"school name".myschoolapp.com/app/sso/auth/"custom name ". So far so good; using Chrome (and in incognito mode), when i type in https://"school name".myschoolapp.com/app/sso/auth/"custom name“ it goes to https://”school name".myschoolapp.com/app/external#login, where the user is prompted to authenticate.

For the Redirect Url, I set it to https://www."Our Third Party App Domain".com/path?sso_token={token}. From my understanding this the Url the user will go to when successfully logged in.

My question is:
I am able to log in successfully when presented the Blackbaud sign in page at https://”school name".myschoolapp.com/app/external#login. However, after i successfully login, I do not go directly to the Redirect Url of https://www."Our Third Party App Domain".com/path?sso_token={token}. Instead, I go to the Blackbaud Resource page where the resource tiles are located (I'll need to create SSO link to a resource board). My question is, is this the correct behavior in that after successfully logging in I am directed to the Blackbaud Resource page versus being redirected to the custom application located at https://www."Our Third Party App Domain".com/path?sso_token={token}?

To me, the setup looks correct but I'm not sure if after successful login it automatically goes to the custom app or if i need to create a resource page.

Thanks
