FAQs
Will Fastlane work if I save payer’s payment methods?
Yes, however, the paymentToken returned on the client can be vaulted prior those
creating a transaction on your server. Be aware that we only support vaulting when using the
store_in_vault_on_success boolean in the transaction.sale() request.
Fastlane does not support a flow where a customer or payment_method is created before a
transaction. We hope to support this in a future release.
How long is a paymentToken valid for?
A paymentToken is valid for 3 hours from the time of issuance.
What if the payer’s shipping address is in a location my site does not ship to?
When you initially call braintree.fastlane.create() you have the option of passing in a
list of allowed locations using the addressOptions object. See the Reference Types
section for details.
How should I handle cases where a payer navigates away from the checkout page to add or remove
items?
It is best practice to call the triggerAuthenticationFlow() method every time the
checkout page is reloaded. Internal logic within our SDK will determine whether we will require the
payer to authenticate via OTP again or simply restore the session. In either case, the method will
return the authenticatedCustomerResult . This will also include a new
paymentToken.
