FedEx Forbidden.Error when trying to confirm Shipment

Hi ​@kkraus 

Sometimes this is a FEDEX issue, I’ve seen it happen. The credentials test correctly then this error comes. 

2 things to try here:

1. Try to process again, it may have been some sort of issue on the Fedex side 
2. Try to re-enter the credentials. 

Thank you for the the recommendation ​@Kandy Beatty. Unfortunately, neither of those fixes worked. The same issue is still happening.

Hi ​@kkraus 

Did it work in a test environment previously?

Also, what are the URL’s being used?

I believe it was working in test. For PX.FedExRestCarrier.FedExRestCarrier, the URLs being used are:

• Cancel Endpoint - https://apis.fedex.com/ship/v1/shipments/cancel
• Rate Endpoint - https://apis.fedex.com/rate/v1/rates/quotes
• Ship Endpoint - https://apis.fedex.com/ship/v1/shipments
• Login Endpoint - https://apis.fedex.com/oauth/token

HI ​@kkraus 

Try the endpoints from the help:

https://help.acumatica.com/(W(12))/Help?ScreenId=ShowWiki&pageid=3facd1eb-c78d-4582-9d2b-18522ddb4d4d

I tried replace Cancel, Rate and Ship Endpoint with the links listed in the Help sheet: https://apis-sandbox.fedex.com/ship/v1/shipments/cancel, https://apis-sandbox.fedex.com/rate/v1/rates/quotes, https://apis-sandbox.fedex.com/ship/v1/shipments respectively. Unfortunately, while it would confirm, I can’t even shop for rates. It gives an error that fields can’t be empty. 

I was able to fix this issue by adding certain API’s in the FedEx Developer portal to the project I’m using the credentials for in Acumatica. 
These are the ones I use. Hope it helps if this is still an issue for you.
