Replace your code with this, paypal Deprecated some field like
PAYMENTACTION to PAYMENTREQUEST_n_PAYMENTACTION
AMT TO PAYMENTREQUEST_n_AMT
CUSTOM to PAYMENTREQUEST_n_CUSTOM
$nvpstr = "&TOKEN=" . $token;
$nvpstr = $nvpstr . "&PAYMENTREQUEST_0_PAYMENTACTION=Sale";
$nvpstr = $nvpstr . "&PAYERID=" . $payerID;
$nvpstr = $nvpstr . "&PAYMENTREQUEST_0_AMT=" . $paymentAmount;
$nvpstr = $nvpstr . "&PAYMENTREQUEST_0_CUSTOM=" . $userId;
$nvpstr = $nvpstr . "&PAYMENTREQUEST_0_CURRENCYCODE=".$currency;
you make these changes in "DoExpressCheckoutPayment" API call it should be fine.
You are passing two parameters related to the currency in the "SetExpressCheckout" API call like below :
$nvpstr = $nvpstr . "&CURRENCYCODE=" . $currencyCodeType;
$nvpstr.='&PAYMENTREQUEST_0_CURRENCYCODE='.$currencyCodeType;
But in the "DoExpressCheckoutPayment" API call you are passing only one :
$nvpstr = $nvpstr . "&PAYMENTREQUEST_0_CURRENCYCODE=".$currency;
You should pass only one parameter related to currency in both the API call : $nvpstr.='&PAYMENTREQUEST_0_CURRENCYCODE='.$currencyCodeType;
Once you make these changes in your "SetExpressCheckout" API call it should be fine
