Hello there,

I’m using the WC’s Fees API to give the customers a discount based on their already available credit.

https://woocommerce.com/document/add-a-surcharge-to-cart-and-checkout-uses-fees-api/

The Paypal plugins recently stopped working and is giving me this error: “CANNOT_BE_NEGATIVE Must be greater than or equal to 0. If the currency supports decimals, only two decimal place precision is supported.”

I did a bit of digging and as far as I got was that your plugin is sending to the Paypal API the discount amount which is a negative number, instead of the total. This is a breakdown of the API call from the file woocommerce-paypal-payments/modules/ppcp-button/src/Endpoint/CreateOrderEndpoint.php:

}

Under the “items” object, you will see 2 items, one the normal priced at $0.04 but also a 2nd item which is the discount of $0.01. Under the initial “amount” > “money” object I can see the correct amount of $0.03.

Hope you can help with this please! TIA!

Thanks,
Dragos Micu

Hi @wpharvest,

The handling of negative fees will be improved in the upcoming 1.9.0 update to prevent this error.
In the meantime, you could give it a try with this test package. Feedback about how it works for your application would be appreciated.
Thanks!

Kind regards,
Niklas
