Open Affirm Checkout

Use affirm.checkout.open() to redirect your customers to Affirm Checkout, an Affirm-hosted page to securely complete the loan checkout. When the customer completes their purchase, they are redirected back to your website.

To open Affirm Checkout, call the affirm.checkout.open() function after calling affirm.checkout.

affirm.checkout(checkoutObject)
affirm.checkout.open()

Method arguments

Parameter	Type	Description
checkoutObject required	object	The object containing the customer's checkout data.

Returns

This method returns nothing normally and you will need to specify in the checkout data object the URL to redirect your customers. Unless you have the metadata option set to modal, you will need to handle the callback methods below:

onFail: Called when the customer exits, cancels or is declined in the Affirm checkout flow.
onSuccess: Called when the customer confirms their Affirm loan. Receives a success object, which contains the checkout_id.
onOpen: Called when the customer successfully loads the Affirm checkout flow.

Affirm.checkout.open({
    onFail: function(error) {
    },
    onSuccess: function(checkout) {
    },
   onOpen: function(token){
}
});
