Update the address of a counterparty's payment method.

:::tip [What is a payment method?] A payment method is an individual account or card linked to a counterparty. When you retrieve a counterparty, the response includes an accounts array and a cards array — each entry in these arrays is a payment method with its own id. :::

As only bank account payment methods have an address, you can use this endpoint to update the address of a counterparty's bank account.

To get the payment_method_id for the bank account, retrieve the counterparty and use the id from the accounts array in the response.

You must provide the full address object — all required address fields must be present in the request. Omitted optional fields will retain their existing values.

For more information, see the guide: Update a counterparty's payment method.
