The afterpay.js is used to launch the Clearpay screenflow, where the consumer logs in (or registers) then confirms their payment schedule.
Note
Before this JavaScript can be used, the merchant must call Create Checkout from their server backend and retrieve a checkout token. The token is then used in conjunction with this JavaScript to launch the Clearpay screenflow.
Note
It is only after the consumer completes the Clearpay screenflow and returns to the merchant's website that a subsequent Auth or Capture (Without Auth) call can be completed.
