FedEx Rate Request returns "Rating is temporarily unavailable, please try again later."

Question

I am working on FedEx integrations using testing credentials and the Rate Service has been returning the message "Rating is temporarily unavailable, please try again later." other services ie Ship, Validate etc seem to be working fine.

It was working fine a couple of days ago now every time I am getting the same response. I am not sure if it is something to do with my code or FedEx service is down.

I cannot find anything to check weather their service is down.

Answer 1

Turns out there is a problem with fedex Rating service and they are recommending using production credentials for the Rate service.

I got a response from FedEx via email saying that everyone is facing the same problem as mine and the development team is looking into the issue.

Answer 2

I was able to reproduce the same problem with production credentials.

In my case, the issue as the ShipTimestamp which was three months old.

By setting it to match current datetime, I got no issue.
