Accept Payments with User Redirect to the Checkout Payment Page

General interaction scheme

Redirect to payment page scheme

  1. The client creates an order on the merchant's website.
  2. To give the client a choice of payment options, the merchant sends a payment pre-request and receives a response from the Cascad platform with a list of available methods.
  3. The merchant displays the list of methods, and the client chooses the convenient way to pay for the order.

    You can skip acts 2 and 3

    Sending a payment pre-request is unnecessary if the merchant has defined a payment method for the client and creates a payment invoice after the order creation.

  4. The merchant creates a payment invoice using a public or private API. Having received the invoice, Cascad:

    • Initiates the transaction on the provider side
    • Transmits payment form data to the merchant
    • Sends a Callback to the merchant notifying them about successful invoice creation
  5. The merchant redirects the client to the payment provider's page with the form data.

  6. On the provider's page, the client enters details for payment. The provider sends a debit request to the issuer.
  7. If an additional step of payment confirmation is required (3DSecure or another verification type), the provider redirects the user to the verification page. The client confirms the payment, and the issuer obtains the sent data.
  8. The issuer returns the payment results and completes the transaction.
  9. The provider records the transaction status and returns it to the Cascad platform, and Cascad, in turn, forwards the data to the merchant.
  10. The merchant displays the payment status to the client on the website pages.
  11. Cascad sends a Callback to the merchant notifying them of the payment status.
  12. To clarify the transaction status, the merchant can reconcile the payment by ID or get a complete list of invoice data using a private API. Daily transactional reports are also available on the portal.

Payment pre-request

Use pre-requests to obtain the list of services available for any particular currency.

The payment pre-request doesn't filter services by the invoice amount because the user can pay in other currency than the given one.

Note

There are 2 ways to redirect user to the payment page:

  1. Use flow_data to build html form: form action => action, form method => method form hidden parameters => params (if present in response).

  2. Use hpp_url: redirect user directly to provided url (using GET method).

Reconciliation by ID

Note

Read about invoice statuses in the Guides. Read below about the HTTP status codes used in the API responses.
