Hi @MTS_Chiranjeevi, Thank you for your reply! Just wanted to ask though, does that mean we must change to the REST API integration to solve our problem. As in, can we continue using the NVP API integration? Our system is for small business users and all of them have a different PayPal business account each. Since we don't have access to their accounts, it would be exceedingly difficult for us to change from the Classic API integration to the REST API integration in a short time. If for example we kept using the NVP API integration, would it be possible to stop an online user from using the Pay Later/Pay in 4 option (i.e. not showing the option on the Paypal site) programmatically? If not, is there any way we can distinguish the DoExpressCheckoutPayment call's return of FAILURE due to Pay Later/Pay in 4 from other failures? As I mentioned in my last post, the DoExpressCheckoutPayment call gives no error message when it returns FAILURE (ACK='FAILURE'). We would like to know why we didn't receive an error message such as the failure caused by a retricted account: TIMESTAMP: 2022-12-11T04:15:29Z CORRELATIONID: 7949dafa36340 ACK: Failure L_ERRORCODE0: 10002 L_SHORTMESSAGE0: Restricted account L_LONGMESSAGE0: Account is restricted L_SEVERITYCODE0: Error Looking forward to hearing from you. Regards, June

Hi everyone! We have used the Express Checkout integration (NVP API) in our online system for over 10 years. Never before have we encountered any PayPal issues until now. In regards to the Pay Later option, if an online user selects the Pay In 4 option (from the Paypal site), the DoExpressCheckoutPayment call returns FAILURE ($ack='FAILURE') without any error message. Here is the PHP code: $nvpstr = '&TOKEN=' . $token . '&PAYERID=' . $payerID . '&PAYMENTACTION=' . $paymentType . '&AMT=' . $paymentAmount . '&CURRENCYCODE=' . $currCodeType . '&IPADDRESS=' . $serverName; $nvpstr = $nvpstr . "&NOTIFYURL=" . $notifyURL; $resArray = hash_call("DoExpressCheckoutPayment", $nvpstr); $ack = strtoupper($resArray["ACK"]); This error only occurs where the Pay In 4 option is selected (i.e. it works fine if the user pays the full amount). We would like to know if there is any NVP filed for the Pay Later option and/or how to integrate it into our system. Please give us some suggestions regarding how to solve this problem. Any help would be appreciated, thank you. June
