401 error using a Get with an acess token

I get an access token using the helper and use it to run a Get. Status returns 401 Unauthorized and the body shows “SYSTEM.SERVICE.NOT_AUTHORIZED”,
“You are not authorized to use this service. Authenticate first.”

Has Postman done its job and I need to talk to the API hosting people about this?

Thank you.

Yep. Seems to be that you don’t have access to the right API keys or authorization method.
