braintree

Get Braintree client token

Returns the Braintree client token the browser uses to initialize the Braintree JS SDK for this cart, scoped to the Braintree PaymentAccount named by payment_account_id; paypal_enabled reports whether PayPal funding is available through that account. Cart-token authenticated. Returns 422 when payment_account_id is missing, the account is not a Braintree account, or token generation fails; 404 when the cart or payment account is not found; and 410 when the cart has already been processed.

Path Parameters

cart_token

required

UUID of the Braintree PaymentAccount (configured gateway) that issues the client token. Required; a missing value or a non-Braintree account returns 422.

Braintree client token used to initialize the Braintree JS SDK in the browser for this cart.
