Use this method to partially update a payment link. Structure your request to follow the RFC 6902 standard.

To update a payment link, you need its paymentLinkId, which we sent you in the response of the Create Payment Link method.

Note: If you don't have the paymentLinkId, use our List Payment Links method to search for the payment link.

You can update the following properties of a multi-use link:

• expiresOn parameter - Expiration date of the link.
• customLabels object - Label for the payment button.
• credentialOnFile object - Settings for saving the customer's payment details.

You can update the following properties of a single-use link:

• expiresOn parameter - Expiration date of the link.
• authType parameter - Transaction type of the payment link.
• amount parameter - Total amount of the transaction.
• currency parameter - Currency of the transaction.
• description parameter - Brief description of the transaction.
• customLabels object - Label for the payment button.
• credentialOnFile object - Settings for saving the customer's payment details.

Note: When a merchant updates a single-use link, we update the payment URL and HTML code in the assets object. The customer can't use the original link to make a payment.
