Fedex REST API preferred currency issue

[mabaud]

Preconditions and environment

• Magento version : 2.4.7-p4
• A fedex account for Canada and US
• A Magento website configured for Canada
• The ACSD-64325_2.4.7-p3.patch applied

Steps to reproduce

1. Go to the Canadian website
2. Add products to the cart
3. Go to the checkout shipping step
4. Add a valid Canadian address
5. Wait for shipping rates

Expected result

Fedex rates

Actual result

An error occurred:
Can't convert a shipping cost from "USD-CAD" for FedEx carrier.

Additional information

We have this issue because in the fedex request the rateRequestType param is missing the "PREFERRED" value, and the preferredCurrency parameter is missing. This is causing fedex to respond rates in USD instead of CAD, and since we don't have currency rate USD/CAD in Magento, we are getting this error.

Note: we have this issue after applying that b22a00f (with the ACSD-64325_2.4.7-p3.patch)

We didn't have that issue with the SOAP API, Fedex was responding in CAD.
Here a quickfix I made (a patch file, you have to remove the .txt extension):

currency_issue.patch.txt

Workaround : pay for a currency converter service or manually set the currency rates USD/CAD every day :)

Hello,

This is this patch:

I assume it's the file for 2.4.7 related to the ACSD-61622 quality patch:

"ACSD-61622": { "categories": [ "Shipping" ], "title": "Fixes the issue where FedEx's account specific rates are missing in the response.", "packages": { "magento/magento2-base": { ">=2.4.6-p1 <2.4.7": { "file": "os/ACSD-61622_2.4.6-p5.patch" }, ">=2.4.7 <2.4.8": { "file": "os/ACSD-64325_2.4.7-p3.patch" } } } },

So you should apply the quality patch ACSD-61622
