well may be its too late but it will help someone in future for sure.
As we integrated paypal delayed chained payment, you can set a primary account in which all the amount will go and you can also set secondary account in which account will be transfered once they approved by primary account holder.
string endpoint = Constants_Common.endpoint + "Pay";
NVPHelper NVPRequest = new NVPHelper();
NVPRequest[SampleNVPConstant.requestEnvelopeerrorLanguage] = "en_US";
//NVPRequest[SampleNVPConstant.Pay2.actionType] = "PAY";
//the above one is for simple adoptive payment payment
NVPRequest[SampleNVPConstant.Pay2.actionType] = "PAY_PRIMARY";
//the above one for deleayed chained payment
NVPRequest[SampleNVPConstant.Pay2.currencyCode] = "USD";
NVPRequest[SampleNVPConstant.Pay2.feesPayer] = "EACHRECEIVER";
NVPRequest[SampleNVPConstant.Pay2.memo] = "XXXXXXXX";
Now we have to set primary and secondary receivers:
//primary account
NVPRequest[SampleNVPConstant.Pay2.receiverListreceiveramount_0] = TotalAmount;
NVPRequest[SampleNVPConstant.Pay2.receiverListreceiveremail_0] = "XXXx.xxxxx.com";
NVPRequest[SampleNVPConstant.Pay2.receiverListreceiverprimary_0] = "true";
//secondary accounts
NVPRequest[SampleNVPConstant.Pay2.receiverListreceiveramount_1] = (somemoney out of total amount);
NVPRequest[SampleNVPConstant.Pay2.receiverListreceiveremail_1] = "xxxxx.xxxx.com";
NVPRequest[SampleNVPConstant.Pay2.receiverListreceiverprimary_1] = "false";
NVPRequest[SampleNVPConstant.Pay2.receiverListreceiveramount_2] = (somemoney out of total amount);
NVPRequest[SampleNVPConstant.Pay2.receiverListreceiveremail_2] = x.x.com;
NVPRequest[SampleNVPConstant.Pay2.receiverListreceiverprimary_2] = "false";
Don't forget that you have to give a valid paypal account while using delayed chained payment.
Now you get your pay_key which you have to use to execute your payment whithin 90 days so that other secondary receivers get money.
Here is the working code:
String endpoint = Constants_Common.endpoint + "ExecutePayment";
NVPHelper NVPRequest = new NVPHelper();
//requestEnvelope.errorLanguage is common for all the request
NVPRequest[SampleNVPConstant.requestEnvelopeerrorLanguage] = "en_US";
NVPRequest[SampleNVPConstant.ExecutePayment.payKey] = "your pay key";
string strrequestforNvp = NVPRequest.Encode();
//calling Call method where actuall API call is made, NVP string, header value adne end point are passed as the input.
CallerServices_NVP CallerServices = new CallerServices_NVP();
string stresponsenvp = CallerServices.Call(strrequestforNvp, Constants_Common.headers(), endpoint);
//Response is send to Decoder method where it is decoded to readable hash table
NVPHelper decoder = new NVPHelper();
decoder.Decode(stresponsenvp);
if (decoder != null && decoder["responseEnvelope.ack"].Equals("Success") && decoder["paymentExecStatus"].Equals("COMPLETED"))
{
//do something
}
Hope it will help someone.
