Error Paypal Express 10413

Question

I ran into a problem with paypal. I just installed it on a website and it works great in most cases. Several times though, I have error 10413:

L_SHORTMESSAGE0 → The transaction was refused due to an invalid argument. See Additional Error Messages for more information.

L_LONGMESSAGE0 → The sum of the basket amounts does not correspond to the sum of orders.

The strange thing is that this error apparently occurs when this logic is not respected:

ITEMAMT + SHIPPINGAMT - SHIPDISCANT + TAXAMT = AMT

Sum of all L_PAYMENTREQUEST_0_AMT * = ITEMAMT

And in my case, this logic is respected (here is an example of the data sent that caused the error).

: PAYMENTREQUEST_0_INVNUM => "480905"

: PAYMENTREQUEST_0_AMT => "11.96"

: PAYMENTREQUEST_0_TAXAMT => "0"

: PAYMENTREQUEST_0_SHIPPINGAMT => "0"

: PAYMENTREQUEST_0_SHIPDISCAMT => "0"

: PAYMENTREQUEST_0_CURRENCYCODE => USD

: PAYMENTREQUEST_0_ITEMAMT => "11.96"

: PAYMENTREQUEST_0_CUSTOM => User # 551588

: L_PAYMENTREQUEST_0_PAYMENTACTION => Sale

: L_PAYMENTREQUEST_0_NAME0 => Xhilaration Top, sleeveless XXL

: L_PAYMENTREQUEST_0_AMT0 => "3.99"

: L_PAYMENTREQUEST_0_QTY0 => "1"

: L_PAYMENTREQUEST_0_ITEMCATEGORY0 => Digital

: L_PAYMENTREQUEST_0_NAME1 => Hillard and Hanson Top XL Short Sleeve

: L_PAYMENTREQUEST_0_AMT1 => "3.99"

: L_PAYMENTREQUEST_0_QTY1 => "1"

: L_PAYMENTREQUEST_0_ITEMCATEGORY1 => Digital

: L_PAYMENTREQUEST_0_NAME2 => Shipping and handling (USPS)

: L_PAYMENTREQUEST_0_AMT2 => "3.98"

: L_PAYMENTREQUEST_0_QTY2 => "1"

: L_PAYMENTREQUEST_0_ITEMCATEGORY2 => Digital

SHIPPINGAMT and SHIPDISCANT and TAXAMT are always 0 because we ship delivery and promos as items with negative amounts. Therefore, we just need the sum of all L_PAYMENTREQUEST_0_AMT * = ITEMAMT = AMT, which is.

Something else interesting is that it seems random (for example, sometimes it does not work for some data, and the same data will work an hour after).

I don’t know where this can come from, so any ideas are welcome.

Thanks!

Answer 1

I looked for the correlation identifier that you provided and saw that the specific amounts of the goods are not currently accepted for any reason.

paymentrequest_0_itemamt="11.96" paymentrequest_0_invnum="480905" paymentrequest_0_name="Xhilaration Top\, Sleeveless XXL" "Hillard " "Shipping and Handling (USPS)" paymentrequest_0_qty="1" "1" "1" paymentrequest_0_itemcategory="Digital" "Digital" "Digital" 

PayPal has no record of receiving any combination of variables / values ​​for product amounts. We get the total order amount, the total amount of items and position information, but not the specific amount for each item.

This contradicts the above information, and I'm not sure why. To investigate it further, you will need to open a ticket at PayPal.com/mts and provide accurate information about the journal that you send to PayPal and receive it back.
