Can somebody help me with session keys?

Hello,

We'd like to connect one of our group hub with our Power BI report. We'd like to see the list of users synched automatically (it's a hidden group hub, and whoever joins the group grabs a license automatically to our beta software too). So far it seems that Bulk API was not really helpful with that, but Search API would be a great fit.

However, this is where we have our problem - it requires a session key, that we don't know how to get. We use SSO on our site (SAML), and I can't seem to find anything useful in the documentation (https://developer.khoros.com/khoroscommunitydevdocs/docs/search-api-overview)...

Can somebody help me how to make this work?

We're running on Classic currently.

Thanks,
Noémi
