Add a payment instrument
Beta
Last updated: March 25, 2026
You must create a payment instrument for each holding currency you specify. The account details are saved securely in the Checkout.com Vault. You receive a unique instrument ID to use in payout requests, instead of entering the bank details every time.
Call the Add a payment instrument endpoint, and provide the sub-entity ID as the {id} path parameter.
In the request body, provide the following:
label– Your reference for the payment instrumenttype– Set tobank_account.currency– The account's currency, as an ISO 4217 currency codecountry– The account's country, as an ISO 3166 alpha-2 country codeinstrument_details.account_number– The alphanumeric value that identifies the accountinstrument_details.bank_code– The code that identifies the bankdocument.type– Set tobank_statement.document.file_id– The file ID of the document uploaded when adding bank account details
If you're using a SEPA account, see the API reference for more information.

When the result is available, you receive one of the following webhooks:
The first payment instrument added for a specific currency is automatically associated to the payouts schedule for that currency. You need to associate any subsequent payment instruments to use as the destination when a payout is made. For more information, see Scheduled payouts.
