I can successfully access most of the necessary API endpoints that i need, but the CSAPI all return 403 forbidden.
When accessing these I get 403 forbidden (not real customer ID):
But these work (not real serial number):
When trying to get into the portal directly i get very long load times, and sometimes error messages that the data is unavailable or i am no authorized to view it. I am an administrator for our company so i know i have access to it.
There are other links that return request too large errors. Such as when I click on the Product Alert Deltas, Under Inventory when i click on Summary, or when try to get details on a device in the inventory.
