# Adds support for updating Connect parameters of an existing Payment Link

## What’s new

Adds [application_fee_amount](https://docs.stripe.com/api/payment-link/update.md?api-version=2026-08-26.dahlia#update_payment_link-application_fee_amount), [application_fee_percent](https://docs.stripe.com/api/payment-link/update.md?api-version=2026-08-26.dahlia#update_payment_link-application_fee_percent), [on_behalf_of](https://docs.stripe.com/api/payment-link/update.md?api-version=2026-08-26.dahlia#update_payment_link-on_behalf_of), and [transfer_data](https://docs.stripe.com/api/payment-link/update.md?api-version=2026-08-26.dahlia#update_payment_link-transfer_data) as parameters on the [update a Payment Link](https://docs.stripe.com/api/payment-link/update.md?api-version=2026-08-26.dahlia) method. These parameters were previously available only on the [create a Payment Link](https://docs.stripe.com/api/payment-link/create.md?api-version=2026-08-26.dahlia) method. You can also pass an empty string to unset any of these parameters.

This updated money movement configuration applies to all Checkout Sessions created from the [Payment Link](https://docs.stripe.com/payment-links.md) after this change. Existing, active sessions aren’t affected.

## Impact

If you use [Connect](https://docs.stripe.com/connect.md) with Payment Links, you can modify application fees, destination charges, and on-behalf-of settings on an existing Payment Link without needing to create a separate one.
