Pay API Operation

Pay Summary

76 August 7, 2012 Adaptive Payments Developer Guide

 When the payment is complete, PayPal sends an IPN message to the URL specified in the

ipnNotificationUrl field of the Pay request.

Additional Notes About the Pay API Operation

1. With parallel payments, fund transfers to some receivers may occur before others.

Therefore, set reverseAllParallelPaymentsOnError to true. In the event of an

error, this setting guarantees that transfers to all receivers are reversed and all funds are

returned to the sender. If reverseAllParallelPaymentsonError is disabled,

completed transfers are not reversed and funds that have already been transferred are no

longer available to the sender.

2. You can specify your own unique tracking ID in the trackingID field and use this value

to obtain information about a payment or to request a refund. The tracking ID is provided

as a convenience in cases when you already maintain an ID that you want to associate with

a payment. You can also track payments using the payKey.

3. You can use the Pay API operation to make unilateral payments under limited

circumstances. A unilateral payment is a payment that is made to a receiver who does not

have a PayPal account. Unilateral payments can be used with simple or parallel payments

that are implicit or preapproved. Unilateral payments are not designed to be used with

chained payments or payments that require manual approval through the web flow.

When you send a unilateral payment, you send a payment request that includes an email

address for a receiver, and this email address is not linked to a registered PayPal account.

The receiver receives an email notifying the receiver to create an account and claim the

payment.

PayPal holds a payment to a receiver whose email address is not yet registered or

confirmed until the receiver creates a PayPal account and confirms the email address. If a

refund specifies a receiver whose email address is not yet registered or confirmed, the

payment to the receiver is canceled.

4. For a guest payment, do not set the sender’s email address or the preapproval key.

Specifying the sender’s email address prevents the sender from choosing the guest payment

option. Implicit approval and preapproval options are not allowed. Each receiver of a guest

payment must be a verified PayPal business or premier account holder.

5. You can specify a value for either senderEmail or one of the SenderIdentifier

fields. If you use SenderIdentifier to identify the sender, you can only specify

sender.email or set sender.useCredentials to true, but not both;

sender.phone is reserved for future use.

6. Specify senderEmail or sender.email to set up a payment where the sender and the

API caller are the same (implicit approval) or for a preapproved payment.

7. If senderEmail or sender.email is specified in the request, the email address must be

registered with paypal.com. If you do not include one of these fields in the payment

request, the sender can either log in using an existing account that is not associated with a

receiver or create a new account during the payment flow.
