Charge a card on file

After you save a card on file, you can use the Payments API and call the CreatePaymentCreatePayment endpoint to process the saved card. If you're using OAuth, you need PAYMENTS_WRITE permission.

To charge a saved card, use the Payments API and set the source_id and customer_id fields in the CreatePayment object:

  • Replace {CARD_ID} with an existing card ID.
  • Replace {CUSTOMER_ID} with an existing customer ID.
  • Replace {LOCATION_ID} with an existing location ID.
