How to authen new REST API organization workspace

[quyen's hoang]

I see there is new api https://developer.atlassian.com/cloud/admin/organization/rest/api-group-workspaces/

I tried to authenticate API with Organization API key. It always return 403 Fobidden with message poco: rejected authenticated request



Note: I used correct API key and organization ID. I tried to created new key too. But I still get the message as above. 

Thank you!

I too got the same error and then realized that it has to be POST call instead of GET call as mentioned in this documentation Workspaces , and it worked for me also. Hope this will help you also
