    Hi @ajna667,

    Greetings from WebToffee support. Thanks for reaching out to us.

    The error message “UNPROCESSABLE_ENTITY – Should equal sum of (unit_amount * quantity) across all items for a given purchase_unit” is due to the price difference calculated by WooCommerce and PayPal.

    Due to rounding off of tax calculations, there will be a slight mismatch between the total calculated by WooCommerce and PayPal. Since the individual line items and their quantity information is passed to PayPal, the total is separately calculated by WooCommerce and PayPal. Sometimes, the total calculated by PayPal will be a little bit different from that calculated by WooCommerce. The error message is usually displayed because of this mismatch.

    We can avoid this calculation mismatch by sending only the total amount to PayPal. We created a code snippet to achieve this requirement. Please note that, by doing so, you will not be able to see the price of individual line items from your PayPal account anymore, only the total order amount. We hope it is clear.

    Please copy the code snippet from here and paste it into your child theme’s function.php file.
    (WordPress Dashboard > Appearance > Theme Editor > functions.php)

    Kindly check using the snippet and let us know how it goes.
