Build a low-code payment form and learn the basic concepts of integrating Inflow into your application.

Inflow Checkout is a prebuilt payment form that allows business to securely collect payments, directly connected to your international merchant account. The whole user journey is handled within the Checkout.

Checkout lifecycle


  1. When customers are ready to complete their purchase, your App will create a new Checkout Session.
  2. The Checkout Session provides a URL that redirects customers to an Inflow-hosted payment page.
  3. Customers choose their local bank and complete the transaction.
  4. After the transaction, you will receive an event in your payment page or through the webhook.

After a successful | Unsuccessful Checkout, the user will be redirected back to your Application.
