PayPal Express Checkout – Error Code: 10431

Yes, I’m pretty sure that’s stemming from the pricing issue.

I’ve been a little backed up with general support on this and other products of ours, but I’m hiring help with that so I can get back to development. Hopefully we’ll have this resolved and get an updated released in the next 2 or 3 weeks at the most.

We are having the same issue with any order that has a coupon applied or tax applied. Just adding myself to this thread to get updates. Thanks for all your hard work on this anglelleye.

Ok, thanks for letting me know. We have been delayed getting an update released while we try to keep up with our other products and supporting everything. We’ll get to it ASAP, though!

Curious if this will be fixed as part of the 1.1.6.3 update: https://github.com/angelleye/paypal-woocommerce/milestones

The plan for 1.1.6.3 is to include an option to remote itemized details from the order so that it will just send a total amount and the order number to PayPal. Then your details would still be available in WooCommerce, of course.

That way we can get this smaller update released with at least a work-around to stop the failures for people dealing with it, and then we can focus on fixing it for good in either 1.1.7 or 1.2 (as currently planned).

I was trying to get around it but something reduces the amount of VAT I’m using from the discount coupon and this amount is then sent as a line item to PayPal. Naturally the total amount is incorrect then. I even tried a product without the tax but no luck. VAT % was reduced from the coupon; both % and amount.
I actually changed the tax rates totally from the original and still reduction of 24% is used for some reason.

[PAYMENTREQUEST_0_AMT] => 224.00
[PAYMENTREQUEST_0_CURRENCYCODE] => EUR
[PAYMENTREQUEST_0_SHIPPINGAMT] => 0.00
[PAYMENTREQUEST_0_TAXAMT] => 0.00
…
[L_PAYMENTREQUEST_0_AMT0] => 239.00
[L_PAYMENTREQUEST_0_QTY0] => 1
[L_PAYMENTREQUEST_0_NAME1] => Cart Discount
[L_PAYMENTREQUEST_0_NUMBER1] => coupong
[L_PAYMENTREQUEST_0_QTY1] => 1
[L_PAYMENTREQUEST_0_AMT1] => -12.10 <<<— should be 15
[PAYMENTREQUEST_0_ITEMAMT] => 226.9032

Looking forward for the fix =D

Me too. I’ve got a great developer working with me now to help get this resolved. I’m going to get him on this plugin full time, so not only will this get resolved more quickly, but we’ll also have more frequent updates with lots of improvements and new features.

We appreciate your patience!

I’m having the same problem.

It may be a problem with the way WooCommerce pricing works. In tax options I have “Yes, I will enter prices inclusive of tax” selected. However in shipping the cost per order must be entered in excluding tax. So this may be where the conflict is?!

In tax options I usually have “Round tax at subtotal level, instead of rounding per line” selected, but I just tested it being deselected and it didn’t appear to make a difference.

But then again in sandbox mode I can’t get the error to replicate.

@cherrydave,

You are correct about where the conflict is, but as you’ve seen, it’s a tough thing to reproduce. Every time I think we’ve got it licked it winds up happening again.

I’ve got a new developer working as lead on this project and he’ll be working full time on it from now on, so we’ll have more consistent updates and we’ll have this stuff resolved for good before too much longer.

Is there something that could be done to help you guys; Such as narrowing down when the error occurs by providing use cases etc?

The more info the better, yeah, but I think once somebody is on this thing full time we’ll be able to get it worked out. I’ve just been spread too thin.

Ok, I can provide results if necessary. It is just puzzling why VAT (24%) is deducted from the discount (coupon) line item .

I thought I had found a work around that seems to allow orders and payments to go through. All I had done is change the shipping tax status to none and changed the cost per order to include tax.

This will mean we might not miss out on orders, but order notifications will display the incorrect amount of tax.

Accounts receivable will have nightmares but this hopefully helps you guys find the a fix ??

EDIT: I just realised I still had one error notification from paypal on Saturday for an order but an order went through fine this morning. So it is still happening intermittently.

Hi guys

Just a “me too” on this issue – It’s driving me nuts and costing a lot of lost revenue. We have a lot of rounding – with a standard VAT rate of 23% it is a necessity to get either a 9.99 or 12.00 type of price.

Will really appreciate it being fixed ??

As an aside we were put onto this plugin by PayPal themselves, the older one (which didn’t feature PayPal Express) didn’t have this problem

Thanks in advance ??

I’m not sure if it’s up to you to fix this as the issue is with WC logic how it calculates the tax. It seems that coupon discount reduces the VAT from the discount. And they removed the option to have the discount before or after the VAT. Now the discount is only from non-VAT price. And all this just because of some genius who said that no one takes the discount from the VAT inclusive price. Well, many EU countries does that.

Nevertheless, discount should not be subject to VAT, ever.

If you can create the logic that fixes this mess, I’m more than happy ??
