BAHA Headbands Posted August 4, 2014 Author Share Posted August 4, 2014 its a fixed amount. would it act differently if it was a percent? Link to comment Share on other sites More sharing options...
bellini13 Posted August 4, 2014 Share Posted August 4, 2014 Prestashop acts differently in many places based on it being fixed vs percent. a few more things 1) what is your prestashop version? 2) is there a shipping charge? 3) was there tax on this order?

BAHA Headbands Posted August 4, 2014 Author Share Posted August 4, 2014 1) what is your prestashop version? PrestaShop™ 1.6.0.6 - 2.605s2) is there a shipping charge? no3) was there tax on this order? no Link to comment Share on other sites More sharing options...
bellini13 Posted August 4, 2014 Share Posted August 4, 2014 I am unable to reproduce this issue. I have created a simple $10 product that is not taxed. There is no shipping or handling fees. I created a cart rule that subtracts $2 from the order total when the voucher code is supplied. When i checkout and select Paypal (v1.3.6) I am directed to the Paypal website, which shows me the order total of $8 I suggest you try to reproduce the issue on your website, and then provide a screen shot showing the cart summary when you check out.

BAHA Headbands Posted August 5, 2014 Author Share Posted August 5, 2014 I must have been confused. I am sorry. There is a shipping charge that is added to the order. The charge (in this case) is $5. But i will go ahead and reproduce the issue. Link to comment Share on other sites More sharing options...

nathanielleee Posted August 13, 2014 Share Posted August 13, 2014 im having this same issue had to remove paypal usa and go with paypal pro but that module keeps my voucher box from appearing... so many issues with paypal. im using 1.6 on prestashop Link to comment Share on other sites More sharing options...
bellini13 Posted August 13, 2014 Share Posted August 13, 2014 The issue here was a 100% discount was being applied, and the merchant was using express checkout on the checkout page. Not a good configuration. You should only use express checkout on the product page, and use standard checkout on the checkout pages. The reason is that Paypal does not allow you to send them a product subtotal that would equal zero. If a customer adds a product to the cart that is $10, and lets say there is $5 shipping, then the subtotal is $10 and the total is $15. However if you then apply a 100% discount, the subtotal is $0 and the total is $5. Paypal does not allow for this. 2 Link to comment Share on other sites More sharing options...
zanfeld Posted October 8, 2014 Share Posted October 8, 2014 Hello! I am receiving the same error code and been following the instructions that @bellini13 has posted but still it does not work. I deactivated the express payment button and also the shipping charges to avoid the trouble but to no avail. I use a voucher code that gives 60% discount on some products, and everything seems to woork fine during the checkout proccess but when I choose to pay with paypal I get the same 10413 error. Do you have any idea of what could be causing this? My store address is: http://www.zanfeld.com/eshop/en/ Thank you very much in advance. 1 Link to comment Share on other sites More sharing options...
zanfeld Posted October 9, 2014 Share Posted October 9, 2014 Hello again. So, I've been making many tests, disabled rounding, disabled shipping cost. Whenever the product is gonna be paid in full there is no trouble with paypal, but if there is a discount being applied it shows error 10413. Anyone, please, any help!? 1 Link to comment Share on other sites More sharing options...
