You can use the concept of PreApproval in Adaptive payments where you can get the permission from the buyer to charge him any time in the future and once he agrees you will get a preapproval key which you can use in your Adaptive chain Payment API call to disburse the payment to Primary and the Secondary Receiver . This way the buyer will not be charged instantly and you will have the enough time to disburse it .

Flow will be something like this :

1.Preapproval:

NVP Request:
requestEnvelope.errorLanguage=en_US&startingDate=2014-10-19Z&endingDate=2015-10-19Z¤cyCode=USD&cancelUrl=XXXXXXX&returnUrl=XXXXXX&ipnNotificationUrl=XXXXXXXX&maxAmountPerPayment=10.00&maxNumberOfPayments=50&maxNumberOfPaymentsPerPeriod=10&maxTotalAmountOfAllPayments=500.00&memo=This is Preapproval memo&paymentPeriod=DAILY

NVP Response:
responseEnvelope.timestamp=2014-10-18T14:31:26.577-07:00
responseEnvelope.ack=Success
responseEnvelope.correlationId=51317322d3c7d
responseEnvelope.build=13085071
preapprovalKey=PA-6D174595N6325214K

2.Redirect the buyer to PayPal page to agree it :

https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_ap-preapproval&preapprovalkey=PA-6D174595N6325214K

3.Charge the buyer at later time using the PreApproval Key received above :

NVP Request:
actionType=PAY&requestEnvelope.errorLanguage=en_US&cancelUrl=XXXXX&returnUrl=XXXXXX&ipnNotificationUrl=XXXXXX&applicationId=XXXXXXX&memo=Chain Payment via PreApproval¤cyCode=USD&receiverList.receiver(0).email=XXXXX.co.in&receiverList.receiver(0).amount=5.00&receiverList.receiver(0).primary=true&receiverList.receiver(1).email=EXXXXX.co.in.pro&receiverList.receiver(1).amount=2.00&receiverList.receiver(1).primary=false&feesPayer=EACHRECEIVER&preapprovalKey=PA-6D174595N6325214K&pin=123456&detailLevel.DetailLevelCode=ReturnAll
