PayPal IPN Module v1.0 Discount Coupons Issue


Recommended Posts



I am having a issue I have the Credit Class & Gift Voucher contribution installed everything seems to work fine, aside from when I use paypal for the checkout. The coupon discount is not subtracting from the order total on the paypal site .


It shows up fine in the checkout (below) (coupon for 50% off)


Sub-Total: $0.10

FedEx Ground (FedEx Ground 3-7 days): $8.00

Discount Coupons:test1: -$4.05

Total: $4.05


but when sent to paypal is shows


Payment For: Shopping Cart


Currency: U.S. Dollars

Amount: $0.10 USD

Shipping & Handling: $8.00 USD

Total Amount: $8.10 USD


I cannot seem to figure it out I am using the new papal_IPN 1.0. (http://www.oscommerce.com/community/contributions,2679/category,1/search,PayPal+IPN)

Everything works fine when used with authorize.


Any help would be greatly appreciated!

I am having the same issue...


I have this version of tha paypal ipn installed:

12 Jan 2005 - osCommerce PayPal IPN Module v1.1 For 2.2MS2


I am trying to use this members discount contribution:

2 Aug 2002 - Members Discount v2.2


I have run a few tests using different sort orders in "Order Total Modules" in the admin section but nothing seems to work. When I checkout using a paypal sandbox testing acct. the discount never gets passed on to the paypal total.


Can anyone shed some light as to why this is happening?


Thank you for your time.

Ok, I did find a fix for this after a more thorough search :D



In the paypal ipn module, under...


Transaction Type

Send individual items to PayPal or aggregate all as one total item?


I selected aggregate instead of individual and it passed the discounted total to paypal.


Just posted this in case someone stumbles on this thread looking for an answer. :thumbsup:
