Amount to be captured in minor unit of the currency (ex: euro-cents for euros).

ISO 4217 three letter currency code. Must be supported by at least one configured payment rail.

Optional. Name of the attached payment method.

Example: "accounts/acct_RwDJsJd8z0exhtfX2570Q/payment-methods/pm_qlwkdqlwkdq".

Name of the attached customer, if any. If provided, the payment method can't be paid with payment methods attached to other customers.

Example: "accounts/acct_RwDJsJd8z0exhtfX2570Q/customers/cus_b7OA3d8UcuWjG23Rnyh0H"

Ignored when confirm is not set. Device to confirm the payment on. When set, payment_method and payment_method_data are ignored and a PROCESSING
intent is returned. The payment_method on the returned intent should be ignored until the intent succeeds — only then does it reflect the actual
card used on the device. It is recommended to keep polling GetPaymentIntent until it enters either REQUIRES_PAYMENT_METHOD or SUCCEEDED.
When a device operation fails, the intent is reverted back to REQUIRES_PAYMENT_METHOD with the error last_payment_error.device set to this device.

See ListDevices for retrieving available devices.

Indicates that the payment method used to pay this intent should also be attempted to be saved
(tokenized) for future reuse against the attached customer. When the rail supports tokenization
and the provider returns vault credentials, the payment_method on a successful intent becomes a
reusable, customer-attached payment method — equivalent to having run a SetupIntent for the
same card. Saving can fail independently of the charge (e.g. provider omits the vault id); in
that case the charge still succeeds and the failure is logged for ops follow-up.

• OFF_SESSION: Save the payment method for future off-session (merchant-initiated) charges, e.g. recurring
  billing or scheduled subscriptions where the customer is not present. Requires customer to
  be set on the intent and a payment rail that supports tokenisation.
