PayPal Subscription + One time order (NVP)

Question

Sorry if this has been answered somewhere, but from what I found, no one has answered this.

I'll be quick. I've created function that allows for the quick generation of PayPal fields so we can do quick payments through our custom built CMS. Through this, we can create multiple one time payments or subscriptions, however, it appears we can't do both at the same time. Here's an example of what I'm trying to achieve (version 63):

Array
(
    [L_PAYMENTREQUEST_0_NAME0] => XXXXXX
    [L_PAYMENTREQUEST_0_DESC0] => XXXXXXXXXX
    [L_PAYMENTREQUEST_0_AMT0] => 97.00
    [L_PAYMENTREQUEST_0_QTY0] => 1
    [L_PAYMENTREQUEST_0_NUMBER0] => 112

    [L_PAYMENTREQUEST_0_NAME1] => XXXXXX
    [L_PAYMENTREQUEST_0_DESC1] => XXXXXXXXXXX
    [L_PAYMENTREQUEST_0_AMT1] => 37.00
    [L_PAYMENTREQUEST_0_QTY1] => 1
    [L_PAYMENTREQUEST_0_NUMBER1] => 113
    [L_BILLINGAGREEMENTDESCRIPTION1] => Subscription: XXXXXXXXX
    [L_BILLINGTYPE1] => RecurringPayments

    [METHOD] => SetExpressCheckout
    [LANDINGPAGE] => Billing
    [ALLOWNOTE] => 0
    [RETURNURL] => http://XXXXXXXXXX/confirm-order
    [CANCELURL] => http://XXXXXXXXXX/checkout/cancelled
    [CURRENCYCODE] => AUD
    [PAYMENTREQUEST_0_ITEMAMT] => 134
    [PAYMENTREQUEST_0_SHIPPINGAMT] => 0
    [PAYMENTREQUEST_0_AMT] => 134
    [PAYMENTREQUEST_0_CURRENCYCODE] => AUD
    ....

And this is what I'm getting back

[L_ERRORCODE0] => 10480
[L_SHORTMESSAGE0] => Invalid Data
[L_LONGMESSAGE0] => Invalid billing agreement type.
[L_SEVERITYCODE0] => Error

Could anyone enlighten me on what I'm doing wrong? I've done some searching, but all results have come up empty.

Thanks!

Answer 1

You are missing L_BILLINGTYPE0 and L_BILLINGAGREEMENTDESCRIPTION0 in your data, add them and you should be set :)
