I am using the Service API for importing a product catalog (nodes, products, variants, images).
On my dev environment all requests work fine.
On the staging environment all the GET requests return 401 Unauthorized, but the POST requests go through.
However, copying the url, payload and token from a debug session and executing the same GET request from Postman is successfull...
What could be wrong?
I have checked that the Administrators group have both ReadAccess and WriteAccess for EPiServerServiceApi in tblUserPermission
