When live keys are added and a coupon for 100% discount is applied and the only fee is the shipping fee, following error occurred. for the sandbox, it works fine so Andrew summed up this as below.

PayFlow API call failed.

Error Code: 7
Detailed Error Message: Field format error: 10413-The totals of the cart item amounts do not match order amounts.

Summery of the issue

First, if we look at the log, with Line Item Details disabled, we should not be getting a FREIGHTAMT value filled in
When that Line Item Details option is disabled, the PayPal request should be very basic, and include nothing but the total AMT being charged
It seems that we are dropping the actual line item amounts, but we're still adding FREIGHTAMT, and I think that's what's triggering the error on the live server
When it sees FREIGHTAMT, it expects to also see taxamt, handlingamt, and the individual line item amounts
And when it doesn't see those, it throws that error we're facing
