Setup Function

The setup function creates and initializes the Paysafe Checkout in an overlay. It has the following parameters:

  • The Public API key provided in the Business Portal. Note that this key can only be used to generate payment handle tokens for use with payments, and has no other API access rights, such as those required for taking payments. Consequently, this key can be exposed publicly in the user's browser.
  • An options object contains the environment to use (Test or Live), the payment amount, currency, and several parameters to show additional features in the payment form.
  • A resultCallback function receives the Paysafe checkout instance, handle successful payment handle (by sending the payment handle to your merchant server), or respond to any errors caused by a failed payment handle creation.
  • An optional closeCallback function you handles the customer closing the payment overlay.
  • An optional riskCallback function to receive the amount and payment method which Customer has selected and run your risk checks before payment handle is created. Depending on the riskCallback response, Payment handle will be created and returned in resultCallback (Applicable to only Cards, PaySafe Cash, VIPP, Sightline, and Apple Pay).

The function signature is as follows:

paysafe.checkout.setup (apiKey, options, resultCallback, closeCallback, riskCallback)
