AdaptivePreApproval Component
Properties Methods Events Configuration Settings Errors
The AdaptivePreApproval component is used to create, retrieve, and cancel preapproval transactions.
Syntax
nsoftware.InPayPal.Adaptivepreapproval
Remarks
The sender of a payment must approve the transfer. The sender can log in to paypal.com to approve each payment, preapprove payments, or when the sender is your application, be implicitly approved to make payments. There are 3 kinds of payment approvals:
- Explicit approval payments, in which the sender logs into paypal.com to approve each payment. Explicitly approving payments is the traditional way to pay with PayPal. This method is the only option unless the sender has set up a preapproval agreement or you, the API caller, are also the sender.
- Preapproved payments, in which a sender logs into PayPal and sets up preapprovals that approve future payments; for example, for a specific vendor. The sender logs into paypal.com once to set up the preapproval. After the preapproval is set up, payments are considered approved, and specific approval is unnecessary.
- Implicit approval payments, in which your application is both the sender of a payment and the caller of the Adaptive Payments Pay API. In this case, the payment is drawn from your own account, which eliminates the need for approval.
To set up a preapproval request, you must specify values for the following required properties (in addition to your PayPal credentials):
| StartingDate | First date for which the preapproval is valid. It cannot be before today's date or after the EndingDate. |
| EndingDate | Last date for which the preapproval is valid. It cannot be later than one year from the StartingDate. |
| MaxTotalPaymentAmount | The preapproved maximum total amount of all payments. It cannot exceed $2,000 USD or its equivalent in other currencies. |
| CurrencyCode | The code for the currency in which the payment is made. You can specify only one currency, regardless of the number of recipients. |
| CancelURL | URL to redirect the sender's browser to in the event he cancels the preapproval. |
| ReturnURL | URL to redirect the sender's browser to after the sender has logged into PayPal and confirmed the preapproval. |
| ClientDetails | Information about the sender to whom the preapproval will be sent. |
Upon a successful CreatePreApproval request, the PreApprovalKey property will contain a key that may be used in the AdaptivePay component to identify this preapproval. It is also used when canceling or retrieving the details of a preapproval, by simply passing the value to the PreApprovalKey parameter of the CancelPreApproval or GetPreApprovalDetails methods.
Note: Preapproval requests require an advanced permission level.
