Stored Instruments API (Beta)

The Stored Instruments API lets developers empower shoppers to save credit cards, bank accounts, and PayPal accounts for a faster checkout experience. You can create, modify, list, and delete stored instruments, as well as set default stored payment instruments for a given customer.

This API consists of endpoints that use two different servers:

• Stores V3 server (api.bigcommerce.com) — Most operations, including listing, importing, updating, and deleting instruments. Authenticate with an X-Auth-Token header and the Stored Payment Instruments OAuth scope.
• Payments server (payments.bigcommerce.com) — For PCI-compliant operations that handle raw card data, such as attaching an instrument to a customer. Authenticate with a Bearer instrument access token (IAT).

For detailed request and response examples, see the Stored Instruments guide.
