Securely store and manage customer details and payment information in our Vault. You can reuse these stored details for future payments, so your customers don't have to re-enter their payment information each time they make a purchase.
You can store two sorts of objects in the Vault: customers and payment instruments.
A customer object contains the details of a particular customer, like their name, email, and phone number. Each customer has a unique ID (for example, cus_y3oqhf46pyzuxjbcn2giaqnb44), to which you can associate multiple payment instruments. You can also set a default payment instrument for the customer, which will be charged if you use the customer ID as the source when making a payment request.
A payment instrument allows you to store the details of a payment card. Each payment instrument has a unique ID (for example, src_nwd3m4in3hkuddfpjsaevunhdy), which you can use as the source or destination for payments. An instrument can only be associated with one customer.
