Sum of purchase item amounts does not match total amount

Hi! As far as I known, Paytrail doesn't support decimal quantities.

I guess we could just check for any decimal quantities and skip including the order items in the payload.

Hi! We have had decimal quantities for ten years now and we have used Xocovis' Paytrail module where this has been handled also with the current Paytrail API.

Paytrail proposed this kind of approach:

The description field can be used to convey information about the contents of the order item. This could also include the quantity, for example: "1.5 meters" or "1.5 kg".

In this case:

The units field should always be set to 1, if the quantity is provided in the description field.

The unitPrice field should contain the total price of the sold product (not price per unit, but the full price for the quantity).

This way, the Paytrail interface would display both the sold quantity (e.g. 1.5 meters or 1.5 kg) via the description field and its price via the unitPrice field.

Could the module handle this in case of decimal quantities?

tuutti → changed the visibility of the branch 3531710-sum-of-purchase to hidden.

tuutti → changed the visibility of the branch 3531710-sum-of-purchase to active.

This should be fixed in the latest 3.x and 4.x releases.

Thank you for very quick response and fix! A purchase with decimal quantities was successfully processed.

By the way, I am missing ApplePay which we have enabled if we use Paytrail's payment page. Is there some additional configuration to enable ApplePay (which I can see in test mode)?

It should be listed under "Mobile payment methods" when using test credentials:

If you're using real credentials then you might have to enable it somewhere in Paytrail's merchant panel.

ApplePay is enabled and domain listed in the merchand's panel because we have had it available in the Paytrail payment page, but I will ask help from Paytrail if they need to do something so that ApplePay becomes available with your module.

The issue does not seem to be fixed in the latest beta and dev releases:
