Checkout Pages

Use Finix to build a custom low-code checkout form.

Checkout Pages

Using checkout pages you can quickly accept payments from buyers with minimal development work. Checkout pages are a low-code solution that enables you to create a customizable payment page where buyers can easily enter their payment details and submit a payment on both desktop and mobile devices.

Checkout pages are only available via the Finix API. If you want to create a similar experience on the Dashboard, look into our Payment Links.

Checkout Form

Buyer Perspective

  1. When your buyers are ready to complete their payment, create a checkout_form
  2. The checkout_form provides a URL you can send to buyers to redirect them to a Finix checkout form.
  3. Buyers enter their payment details into the checkout form and complete their payment.

Supported Payment Methods

Checkout pages support:

  • Card payments
  • Bank account payments (ACH in USA)

For more details about ACH payments, see ACH Direct Debit.

Expiration

By default, checkout_forms expire after 10 minutes. You can extend the expiration date to a maximum of 3 weeks. Please note the expiration time of the checkout_form must be less than your cart expiration time; otherwise, timeout issues can come up for your buyers when submitting a payment.

checkout_forms can only be used once. After a buyer makes a successful payment, the checkout_form cannot be used again. If a buyer returns to a successful checkout_form link, they'll see a You have already paid message and/or get redirected to a new page.

Finix API

To create a checkout form, include:

  • The ID of the Merchant that the payment will be created under.
  • The amount of the transaction.
  • Any additional URLs (terms of service required).
  • Allowed payment methods.

At this time, only APPROVED Merchants with one of the following processors can create checkout pages:

  • DUMMY_V1
  • LITLE_V1
  • FINIX_V1
