I tried to chat just like its described above and the technician had no idea what I was talking about and did not know that the old shipping manager is retired as of may 31 2025. Im having an issue where even after being forced to create the shipengine account with USPS, I cant add my FEDEX nor my UPS carriers into shipengine.

When inputting all the correct fedex info it states:

"An error occurred while registering the carrier. Please confirm the details below and try again."

When trying to add UPS: upon entering the acc number, postal code and country code, a "Connect carrier popup" window appears to log into ups, when I enter the user name we have associated with ups and press next, I get this error message:

Access Denied
You don't have permission to access "http://www.ups.com/lasso/login" on this server.

The chat technician simply said:

I have consulted our backend team and it seems that it will be best to contact Shipengine for this process and for further information.
