Is it possible to generate a Yammer API access token with Yammer and Sharepoint scopes/workloads?

Question

Hi,

I'm trying to generate Yammer API access token that I can also use to download SharePoint files that are shared on Yammer. I've been generating access tokens using https://login.microsoftonline.com/organizations/oauth2/v2.0/authorize url.

I know that I'm able to use multiple permissions in the same request for the single scope, but is it possible to generate an access token that use Yammer API and Site-Id SharePoint API scopes/workloads together?

I'm trying to use the Yammer API scope along with site-id SharePoint scope, however I haven't not been able to use it together. The authentication fails when both scope are used at the same time, I can see "Error: invalid_client' in the response". It means I'd need to use two access tokens. Is it possible to generate an access token that use Yammer API and Site-Id SharePoint API scopes together?

Yammper API scope:
https://api.yammer.com/user_impersonation Files.ReadWrite.All Sites.ReadWrite.All Directory.ReadWrite.All offline_access

Site-Id SharePoint API scope:
https://grsbo.sharepoint.com/MyFiles.Write Sites.ReadWrite.All User.ReadWrite.All offline_access

Thanks

Hi @GR

NO！

You can only get tokens for one API endpoint because access tokens are issued based on the API audience you want to access, and it is unique, i.e. a token can only have one API audience, so using multiple API scopes to request an access token is obviously not supported.
