PayPal Error 10412

Hi there,

According to PayPal, this error occurs when a PayPal InvoiceID value is already associated with another transaction in the PayPal system:

PayPal checks that InvoiceID values are unique for any particular merchant. If you send an InvoiceID value that is already associated with another transaction in the PayPal system, PayPal returns this error code. Inform the customer and redirect him or her to restart the Express Checkout flow. However, you might not be able to correct this error during an actual checkout. In this case, modify your implementation of Express Checkout to ensure that you generate unique invoice ID numbers.

I think the next best step would be to rule out any third-party interference that could be affecting order numbers or IDs on your site.

Do you have any plugins installed that could potentially affect these? Would you mind copying and pasting your System Status Report into this thread so that I can check for any red flags there? You can find this by going to WooCommerce > Status > System Status > Get System Report in your WP-Admin dashboard.

Looking forward to your reply.

@laceyrod – any news on this?

Hi @cmcpress –

Thanks for sending your Status Report. I’m not seeing anything in particular standing out that looks troubling. I would still proceed with testing for conflicts to be sure, however. To do this, you would need to take the following steps: https://docs.woocommerce.com/document/woocommerce-self-service-guide/

If you aren’t able to find any culprits, at that point, you’d have to restart the checkout process to generate a new Transaction ID and see if that helps.

This thread has been inactive for a bit, so I’m going to mark it as Resolved now. Please feel free to open a new thread if you have any further questions or still need help.

Cheers!
