# Partially update payment link

`PATCH /payment-links/{paymentLinkId}`

Use this method to partially update a payment link. Structure your request to follow the [RFC 6902](https://datatracker.ietf.org/doc/html/rfc6902) standard.

To update a payment link, you need its paymentLinkId, which we sent you in the response of the [Create Payment Link](https://docs.payroc.com/api/schema/payment-links/create) method.  

**Note:** If you don't have the paymentLinkId, use our [List Payment Links](https://docs.payroc.com/api/schema/payment-links/list) 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.
