Store a customer's card or bank account as a payment instrument to reuse it in future payments or payouts.


Create a card payment instrument

You can store a card as a payment instrument in two ways: using the /payments endpoint, or using the /instruments endpoint.

In both cases, you can create a payment instrument for a new customer, or an existing one:

  • If you provide a new email in the customer object, a new customer will be created and linked with the new payment instrument.
  • If you supply an existing customer ID or email, the new payment instrument will be linked to that existing customer.

Using the /payments endpoint

Make a payment (with a card token or full card details) or verify a card with the /payments endpoint, and the ID of the newly created payment instrument will be included in the response.

For the full API specification, see the API reference.

Tip

We recommend this flow if you perform payments with us, because we will check the card is valid before storing it.

Response example

If the request was successful, you will receive 201 success response. This will include a source.id (prefixed with src_) – this is the payment instrument ID. You can use this in future payment requests.

It will also include the customer.id (prefixed with cus_) – the ID of the customer to which the new payment instrument has been linked.
