I'm using Express Checkout in Paypal and trying to pass discount as a separate item taking reference as Paypal Express Checkout provide full items discount
&L_NAME0=Item1
&L_NAME1=Discount
&L_AMT0=1.01
&L_AMT1=-50
&L_QTY0=50
&L_QTY1=1
&MAXAMT=27.51
&AMT=2.51
&ITEMAMT=0.01
&TAXAMT = 2.5
According to the above parameter my Item Amount is getting 0 and i've added 0.01 as mentioned in the reference. It is like :
Item Cost = 50.00
Tax = 2.5
Discount = 50.00
But I get
"The totals of the cart item amounts do not match order amounts."
Any help will be appreciated. Thanks
