Google chat API external invitation

[eldad-knock]

Hey
I’m trying to use google chat API and create a space which allows external users.
To do that I’m calling the create.space API and marking “externalUserAllowed” to true but I get the following error every time:
“Authorization failed. The credential used in the request can’t be used to create a space.”
When I set the “externalUserAllowed” flag to false, everything works fine.
Do you know on any special scopes I should request from the user that might make the difference?

Thanks!

Have you checked if in the admin console, you have allowed external members into Spaces?

Yep, I did
