Detailed Integration Steps

  1. Create a Sessions Request API Call:
    • This call replaces your
      Secure Acceptance
       hash value.
    • Refer to the
      Unified Checkout
       API Documentation for detailed instructions and examples. For information about the Sessions API see the
      Sessions API
       section of the
      Unified Checkout
       Developer Guide      .
  2. Initiate
    Unified Checkout
     in Your Web Page:
    • Unified Checkout
       is initiated using a JavaScript-based application instead of the POST method used in
      Secure Acceptance
      .
    • Implement the
      Unified Checkout
       SDK on your webpage. For information about implementing
      Unified Checkout
      , see the
      JavaScript API Reference
       section of the
      Unified Checkout
       Developer Guide      .
  3. Capture the Response on Your Web Page:
    • Ensure your frontend captures the response from the
      Unified Checkout
       process.
    • Handle the response appropriately to update the user interface and communicate transaction status. For information about handling responses, see the
      Handle Errors
       section of the
      Unified Checkout
       Developer Guide      .
  4. Recommended: Webhook implementation:
    • Subscribe to the
      Unified Checkout
       webhook to receive the full payment details
Information that is captured by
Unified Checkout
, including the billing and shipping address, can be retrieved using the payment details API.
