call to DoReferenceTransaction method giving error

问题:

I am calling CreateBillingAgreement after SetExpressCheckout, both are successfull. BILLINGAGREEMENTID is returnd by CreateBillingAgreement.

This BILLINGAGREEMENTID is passed as REFERENCEID to DoReferenceTransaction.

NVP is constructed as :

$nvpstr = '&TOKEN=' . $token . '&REFERENCEID=' . $billing_agreement_id . '&PAYMENTACTION=' . $paymentType . '&AMT=' . $FinalPaymentAmt;
    $nvpstr .= '&CURRENCYCODE=' . $currencyCodeType . '&IPADDRESS=' . $serverName .'&L_ITEMCATEGORY0=Digital'.'&DESC='.urlencode("Test Recurring Payment( $" . $_SESSION["Payment_Amount"] . " monthly)");

    $nvpstr.="&L_PAYMENTREQUEST_0_ITEMCATEGORY0=Digital";
    $nvpstr.="&L_PAYMENTREQUEST_0_QTY0=Digital";
    $nvpstr.="&L_PAYMENTREQUEST_0_NAME0=Test Name";
    $nvpstr.="&L_PAYMENTREQUEST_0_AMT0=".$_SESSION["Payment_Amount"];

    $nvpstr.="&L_NAME0=Test Name";
    $nvpstr.="&L_DESC0=".urlencode("Test Recurring Payment( $" . $_SESSION["Payment_Amount"] . " monthly)");
    $nvpstr.="&L_AMT0=".$_SESSION["Payment_Amount"];
    $nvpstr.="&L_QTY0=1";

回答1:

Is it a live or a sandbox API call?

You need to have Reference Transaction activated on your PayPal account to be able to call this API.

The Reference Transaction API is not available for everybody. I would advise to contact your PayPal representative to ask them to activate this on your PayPal account.

If you are doing this on the sandbox, you should simply upgrade your sandbox account to a Pro account. This should activate Reference Transaction on the sandbox account.

To be sure, you should ask PayPal if your sandbox account has Reference Transaction enabled.

Can you send the full API call in your question please?

Update

I see something strange in your code:

$nvpstr.="&L_PAYMENTREQUEST_0_ITEMCATEGORY0=Digital";
$nvpstr.="&L_PAYMENTREQUEST_0_QTY0=Digital";

Change it by:

$nvpstr.="&L_PAYMENTREQUEST_0_ITEMCATEGORY0=Physical";
$nvpstr.="&L_PAYMENTREQUEST_0_QTY0=1";

Update 2

I see few errors in the API call:

&TOKEN=EC-30M31870BS241854X&
REFERENCEID=B-81S156104Y376273D&
PAYMENTACTION=Sale&
AMT=3&
CURRENCYCODE=USD&
IPADDRESS=paypalrecurring.com&
L_ITEMCATEGORY0=Digital&
DESC=Test+Recurring+Payment%28+%243+monthly%29&
L_PAYMENTREQUEST_0_ITEMCATEGORY0=Digital&
L_PAYMENTREQUEST_0_QTY0=Digital&
L_PAYMENTREQUEST_0_NAME0=Test Name&
L_PAYMENTREQUEST_0_AMT0=3&
L_NAME0=Test Name&
L_DESC0=Test+Recurring+Payment%28+%243+monthly%29&
L_AMT0=3&
L_QTY0=1string(606) 

Provide a valid IP address in the IP address variable.

Replace

L_PAYMENTREQUEST_0_QTY0=Digital&

by:

L_PAYMENTREQUEST_0_QTY0=1&

In the last parameter there is a wrong parameter replace:

L_QTY0=1string(606) 

by:

L_QTY0=1

Eventually change the item category from Digital to Physical. I know you need special rights to do Digital Goods with PayPal.

L_ITEMCATEGORY0=Physical&
L_PAYMENTREQUEST_0_ITEMCATEGORY0=Physical&
