Types

When it comes to accepting payments there are a number of ways you can integrate with WhenThen's API. From Drop-In to Elements - choose the right checkout experience for you.

Building your own Checkout?

Use our APIs and build your own payment form or integrate with your existing checkout experience.


With our API-only solution, you have two options for accepting card payments:

  • Use our Vault SDK or Vault APIs to securely encrypt payment method details. This helps you ensure PCI compliance, as you're only required to submit SAQ A.
  • Collect and pass raw card data. This requires you to assess your PCI compliance according to SAQ D, the most extensive form of self-certification.
