A PayPal Adaptive Chained Payment API creation is necessary and coding is required only. Placement on website will be handled locally. I'm looking to have a PayPal Adaptive Chained Payment API created where a customer clicks an icon, situated on a specific website and initiates a purchase for one item. Their action initiates the process to remit payment to a primary and secondary receiver through PayPal, where each receiver is responsible for their own PayPal fee. The customer is aware only of the primary receiver and sees that the full amount of the purchase is paid to that primary receiver. The secondary receiver simultaneously receives a specific payment of $20 for each transaction. A 6% sales tax is only collected should the customers mailing address be within the state of Maryland. Each purchase would be for a maximum of one item and a postage/delivery amount would be assessed at a universal rate for each transaction. Should the above be your forte', please respond. Additionally, the code required to accomplish the above task should also be encrypted, prior to delivering for website placement. I would need both. Thank you.
