Multiple shipping methods mix of fixed price or percentage of product price. All work fine except for one which offers a 10% discount on the product price. So total product price of order, say, $25.90 then shipping price in checkout shows as $-2.59, great. Tax also appears to be adjusted correctly, so all set to go. In paypal payment method have the **Send details of the order** option set to NO. At end of checkout redirect to PayPal correctly. In paypal payment method change the **Send details of the order** option to YES. At end of checkout redirect to PayPal and get this error. [ Paypal Error](https://www.paypal.com/webapps/shoppingcart/error?flowlogging_id=20a327941b4cf&code=AMOUNT_ERROR&mfid=1591295861947_20a327941b4cf) - Found description of that error here [ Paypal Error Description](https://docs.easydigitaldownloads.com/article/2030-paypal-error-things-dont-appear-to-be-working-at-the-moment) Looks to me like PayPal does not like negative prices for order items - the shipping price is passed to PayPal as an order item. Solution looks easy enough - if the shipping price is negative don't pass it to PayPal but add to the **discount\_amount\_cart** value which is passed to PayPal. Know of any reason why that would not work? Could this change be made to paypal.php - or would it be better to create our own branch? Other issues to consider - in theory a discount could even apply to selected payment methods! What happens after all discounts applied the total order value is negative :evil: ?

As soon as I remove the discount, everything works fine. Is there a better way to offer discount on shipping method ? thank you")* Hi, Well, yes, PayPal doesn't support negative prices. Usually, in such cases, I would recommend to just turn off the "send order details" setting of the PayPal payment method. Using the discount_amount_cart field for the shipping fee when the shipping fee is negative is something that could be implemented. But then, the customer would see "discount" instead of "shipping" for the shipping fee, and if he has a coupon, the amount of the coupon would be summed together with the amount of the shipping fee. And then, you would have the same query for payment fees, product prices (which can also be negative). It looks like a hack of the API of PayPal. Ideally, it would be better that PayPal accept negative items as long as the total amount is positive. As that's not supported by PayPal I would recommend to just turn off the "send order details" option. When the total order value is negative, HikaShop forces it to 0 when the cart is being loaded. And when the total cart/order amount is 0, the payment method selector is removed from the checkout automatically and no call to the payment methods is done. At the end of the checkout the order will be created and if the "validate free order" plugin is activated, the order will be directly confirmed. Most payment gateways don't accept transactions with a value of 0 or negative, so that's why we've done it like that as it wouldn't work otherwise.

Instead of the shop owner having to disable sending order details it would be more sensible if PayPal just accepted negative item prices ... the final total of the payment is the most important bit. Hiding the order details to get round the problem just reduces the customer's ability to check how the total arrived at (although they will have an email with that information). Negative item prices should not matter as long as the total is positive.* Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtLzI4LXNoaXBwaW5nLW1ldGhvZHMvOTAwMDc4LWFwcGx5aW5nLWEtZGlzY291bnQtb24tdGhlLXNoaXBwaW5nLW9wdGlvbi1sZWFkcy10by1hLXBheXBhbC1lcnJvcj90bXBsPW1hcmtkb3du) or [Create an account](/component/users/registration?Itemid=101) to join the conversation. - **[nicolas](/forum/user/63-nicolas "View nicolas's Profile")** - [![nicolas's Avatar](https://www.hikashop.com/media/kunena/avatars/resized/size144/users/avatar63.png?1793428657)](/forum/user/63-nicolas "View nicolas's Profile") - [ Offline](/forum/user/63-nicolas) Less More - Posts: 86358 - Thank you received: 14293 - - 6 years 3 months ago [\#322300](#322300) by [nicolas](/forum/user/63-nicolas "View nicolas's Profile") Replied by *[nicolas](/forum/user/63-nicolas "View nicolas's Profile")* on topic *[Applying a discount on the shipping option leads to a Paypal error](/forum/28-shipping-methods/900078-applying-a-discount-on-the-shipping-option-leads-to-a-paypal-error#322300 "-- HikaShop version -- : 4.3.0 -- Joomla version -- : 3.9.19 -- PHP version -- : 7.3.18 -- Browser(s) name and version -- : Firefox lastest -- Error-message(debug-mod must be tuned on) -- : www.paypal.com/webapps/shoppingcart/erro...861947_20a327941b4cf Hi!

You can give any price and quantities to the products in the order details to authorize.net. It will display them, but it will only take into account the main total amount you're giving it, even if the total of the items don't match. That way, it is a lot easier to handle such edge cases since the payment will always work with the correct amount.
