Rest API access token SSO

[Anonymous]

I use a SSO from a 3rd party to log into PBI desktop/reporting services. (When I log in I’m propped to that site, input credentials, and then am redirected to PBI).

I want to use the rest API so I can use python to refresh datasets but I’m unable to authenticate. Is there a special process to obtain an access token when using a 3rd party identity management SSO service?
