Initiate future transactions

DOCSCURRENT

Last updated: May 7th, 1:48am

Website Payments Pro merchants can initiate future transactions using a transaction ID

Use your payer's original transaction ID to charge them later with reference transactions. A reference transaction is a transaction you initiate through an established contract with the payer and from which you can derive subsequent payments.

Important: Reference transactions are only available to Website Payments Pro merchants who have migrated to an Advanced Credit and Debit Card integration.

Know before you code

This server-side integration uses Orders REST API. To complete this integration, you will need:

An advanced credit and debit card payments integration.

The original transaction ID for the payer and amount of the transaction.

A previous order ID.

Reference transactions are also available if you have previously integrated with the DoReferenceTransactionAPI operation (NVP, SOAP).

Use Postman to explore and test PayPal APIs.

How it works

The payer generates a transaction ID when they purchase an item on your site.
The payer agrees to a reference transaction.
Use the transaction ID in future reference transactions using the same payment method.

Use cases

Use reference transactions to:

Save payers' card details for a future payer-initiated transaction.
Initiate transactions to charge the payment method based on a previously agreed contract.

Create an order

Provide an order ID from a previous transaction or generate a new one.

API endpoint used: Create order

1curl -v -X POST https://api-m.sandbox.paypal.com/v2/checkout/orders

12        "value": "100.00"
13      }
14    }
15  ]
16}'

Modify the code

After you copy the code in the sample request, modify the following:

Access-Token: Your access token.

PAYPAL-AUTH-ASSERTION: Your PayPal-Auth-Assertion token.

BN-CODE: Your PayPal Attribution ID to receive revenue attribution. To find your BN code, see Code and Credential Reference.

intent: The value of intent in this sample is CAPTURE, which captures the payment immediately. You can choose to separate the authorize and capture actions by changing the intent to AUTHORIZE.

Step result

A successful request results in the following:

A return status code of HTTP 201 Created.
