PayPal Express Checkout – Error Code: 10431
-
Hi
I have been getting a lot of PayPal Express Checkout – Error Code: 10431 errors and submitted the problems to Paypal who said the following. Hope you can help out…
When checking the request your system sent to PayPal, I found this item number in the request:
42.950000000001
while PayPal was expecting 42.95. And thus the amount doesn’t correspond with other parts of the request.Please check the source code on your system and make sure the prices are correct in the request.
The deeper reason of this is actually a common floating point number issue which is present in all programming languages, that the last digits of floating point numbers are not accurate. It is why floating point numbers are not to be compared with “=” sign in programming languages. There is some more information here:
https://stackoverflow.com/questions/2896013/manipulating-and-comparing-floating-points-in-javaI would guess (from my experience) that the problem is with the plugin, because if a platform or a plugin is wisely designed, they should have logics encapsulated, which means PayPal logics go to PayPal plugin.

This is an issue we are aware of and we’re addressing in the 1.1.6 release of the plugin. I’ve been a little delayed getting this updated thoroughly tested and released, but I’m hoping to have it done within the next couple of weeks.
The issue is due to how WooCommerce passes data in various places, and it’s been tough to troubleshoot because they keep releasing updates that adjust some of the rounding of calculations. They even go so far as to add an additional line item to the order with a value of 1 penny and the name “rounding adjustment”, which is something I just haven’t been able to accept, so again, we’re working hard to resolve this once and for all, and it should be done in the 1.1.6 update. Keep your eye out for it!
Thanks for the quick response.
Will the fix take so long that we should turn off Express until it is ready as even though it does work, we are getting these errors almost every second day which is a losing us a lot of potential sales.
It’s generally caused by some sort of discount or tax calculation. When it fails is anything like that happening?
Do you have logging enabled in the Express Checkout settings? If so, can you provide the log file located at /wc-logs on the web server?

Version 1.1.6.2?
Yes this is still happening after the update
Hi – having the same issue with v1.1.6.2. Any ideas?
Ah, I forgot I moved the issue to the 1.1.7 update because 1.1.6 was already too delayed. Sorry about that. I’m hoping to get 1.1.7 released within the next couple of weeks.
That said, I’m still unable to reproduce this for myself, so I’m a little unsure how it’s happening. With 2 of you giving the same feedback, though, I would say there’s obviously an issue.
Do either of you have anything unique going on with your pricing? Are you using more than 2 decimals in your item prices or anything like that, by chance?
Hi – thanks for the quick response!
Not sure what situation AndyUSSDU has, but I think it may have something to do with a clash with the Bulk Discount module. It only seems to happen when there is a % discount applied to a multiple product order.
As for pricing – no, only 2 decimal places. If it helps, the website is https://www.natrapak.co.nz – add 4 products to get a discount then click the PayPal express button and that’s when I get the error.
Thanks!
Ok, yeah, sounds like another rounding issue (it’s simply not getting rounded at that point as you can see in the API request log).
I’ve got all the details in our GitHub repo. We’ll be sure to focus on this and get it resolved for the next update.
Hey, unfortunately I have troubles with it, too.
Getting a lot of these notification at the moment:
“DoExpressCheckoutPayment API call failed.
Error Code: 10431
Error Severity Code: Error
Short Error Message: Transaction refused because of an invalid argument. See additional error messages for details.
Detailed Error Message: Item amount is invalid.”@soeren-phoenix, are you using the bulk item discount plugin, too?
@angelleye no this plugin is not installed ??
@soeren-phoenix, what about any other plugins that may be doing calculations on the pricing..??
I think maybe WPML Multilingual could be a problem. We use 4 different languages, but we are only using one currency at the moment…
Could W3 Total Cache also be a problem?
