Requests

Pay

The default action for PayPal is Pay. This action has no required input. Optional input includes the PayPal account e-mail address of the consumer, a PayPal page style and/or a Billing Agreement Description. Upon receiving the request, the consumer will be redirected to PayPal for verification and confirmation of the payment and/or billing agreement. A successful payment will include the PayPal account status of the consumer (e.g. verified or unverified), the notetext (if entered by the consumer at PayPal under ‘note to seller’), his e-mail address used as PayPal account, and the country of the consumer.

Service specific parameters

Parameter	Type	Required	Recommended	Description
BuyerEmail	String	No	N/A	E-mail address the consumer uses for his PayPal account.
ProductName	String	No	N/A	In the Paypal payment pages, an overview is shown containing the payment details. If no productname is provided the description is shown there as productname. If a productname is provided, the Productname is shown with the description as a product description.
BillingAgreementDescription	String	No	N/A	A description used for a billing agreement. Provide this if performing recurrent billing. If not provided, the transaction description is used for both the initial payment and the billing agreement. Make sure the description is an accurate depiction of the subscription or service (e.g. ‘2 Year subscription for 24 issues of Magazine X’). This can be 127 characters max.
PageStyle	String	No	N/A	The page style as defined in the merchant PayPal account.
startrecurrent	boolean	No	N/A	Set startrecurrent to true to start the first transaction in a series of recurrent transactions. This will require the consumer to accept a billing agreement when performing the initial transaction. Please note: This is a basic request variable, not a service specific variable.
PayPalOrderId	String	No	N/A	PayPal Order ID, required for the implementation of the Express Checkout functionality. Also see Client SDK - PayPal Express Checkout

Pay response

If the request has a valid structure and a valid signature, a transaction will be created in the Payment Engine and a response will be returned. In this case, an additional action is required before the transaction can be completed. The customer needs to be redirected to the payment environment through the returned redirect URL.

paypalTransactionID is preserved for backwards compatibility. Its value depends on the transaction type it appears on: the PayPal Authorization ID on Authorize transactions, the PayPal Capture ID on Capture transactions, and the PayPal Refund ID on Refund transactions. New integrations should prefer the type-specific fields paypalAuthorizeId, paypalCaptureId and paypalRefundId.

Authorize

The Authorize action reserves funds on the buyer's PayPal account without moving them. The reserved amount stays valid for up to 29 days; during that window the merchant can capture the funds (in one full capture, one partial capture, or several partial captures that add up to the authorized amount) or release them by sending a CancelAuthorize.

Authorize request

An Authorize request is similar to a Pay request. The difference is the action name. For Express Checkout / SDK flow, include PayPalOrderId.

Parameters

Parameter	Type	Required	Description
BuyerEmail	String	No	E-mail address the consumer uses for his PayPal account.
ProductName	String	No	Display name shown on PayPal payment pages alongside the description.
BillingAgreementDescription	String	No	A description used for a billing agreement (127 characters max).
PageStyle	String	No	The page style as defined in the merchant PayPal account.
PayPalOrderId	String	No	PayPal Order ID. Required for the Express Checkout (SDK) flow; omit it for the standard redirect flow. See the Client SDK.

admin_area_2	String	City or locality of the buyer's shipping address (only present when PayPal returns one).

CancelAuthorize

The CancelAuthorize action voids an authorization, releasing the reserved funds back to the buyer. It can be sent on an authorization that is still fully open or one that has been partially captured; in the partial-capture case the remaining (uncaptured) amount is released. PayPal does not support partial voids - a single CancelAuthorize call always releases the entire remaining authorized amount. After cancellation the authorization can no longer be captured.

OriginalTransactionKey	String	Yes	The Key of the Authorize transaction to void. Must be a 32-character hex string.
AmountCredit	Number	No	If supplied, must be equal to or less than the open (uncaptured) authorized amount; otherwise the request is rejected.

Parameters

CancelAuthorize transactions do not carry service-specific output parameters. The voided Authorize is identifiable via the RelatedTransactions block on the response and the push (RelationType "CancelAuthorize" pointing at the original Authorize Key)

Refund

To refund a successful PayPal transaction, use the action Refund. A refund is then performed through PayPal which transfers the amount of the original transaction to the consumers PayPal account.

For the Authorize/Capture flow, the OriginalTransactionKey must refer to the Capture transaction, not the Authorize transaction. Pay-flow refunds continue to refer to the Pay transaction.
