I have been successfully using Express Checkout API for more than a year now, but a client realized that no line items are being sent, so I set about implementing that according to these docs here: https://developer.paypal.com/docs/classic/express-checkout/integration-guide/ECCustomizing/#provide-...
However, after implementing everything as described, the line items are not being sent.
Here is a snippet of the serialized code (we're populating hidden fom inputs and serializing before being sent):
PAYMENTREQUEST_0_ITEMAMT=450.13
PAYMENTREQUEST_0_SHIPPINGAMT=10.36
PAYMENTREQUEST_0_TAXAMT=0.00
PAYMENTREQUEST_0_AMT=460.49
PAYMENTREQUEST_0_SHIPTONAME=Customer+Name
PAYMENTREQUEST_0_SHIPTOSTREET=Address
PAYMENTREQUEST_0_SHIPTOCITY=City
PAYMENTREQUEST_0_SHIPTOSTATE=
PAYMENTREQUEST_0_SHIPTOZIP=ZIP
PAYMENTREQUEST_0_CURRENCYCODE=USD
PAYMENTREQUEST_0_PAYMENTACTION=Sale
PAYMENTREQUEST_0_CUSTOM=custom_info
L_PAYMENTREQUEST_0_NAME1=Product+1
L_PAYMENTREQUEST_0_DESC1=Product+1
L_PAYMENTREQUEST_0_NUMBER1=UPC
L_PAYMENTREQUEST_0_AMT1=%24371.20
L_PAYMENTREQUEST_0_QTY1=1
L_PAYMENTREQUEST_0_NAME2=Product+2
L_PAYMENTREQUEST_0_DESC2=Product+2
L_PAYMENTREQUEST_0_NUMBER2=UPC2
L_PAYMENTREQUEST_0_AMT2=%2478.93
L_PAYMENTREQUEST_0_QTY2=1
I have redacted some things, but this should give you the idea.
Any help is appreciated. Any other info needed let me know.
