    Get up and running and start taking card payments online, by exploring our integration guides and documentation for developers; including libraries, keys and other integration tools.

    Get Started

    Hosted Payment Page

     

    The Hosted Payment Page (HPP) is our PCI DSS v3.2 compliant redirect solution, allowing you capture card data without having to worry about the PCI overhead associated with a traditional API integration.

    Using the HPP along with our SDKs and libraries means that you can have a secure payment form  setup in your application/website in minutes. The library handles the opening, display and response of the HPP on desktop, tablet, mobile or in-app with minimal configuration required. If you are accepting card details via the HPP only, you can attest to your PCI compliance by completing the short PCI DSS Self-Assessment Questionnaire (SAQ) A.

    Step 1 - Set up your server


    We'll start by setting up the server-side code, if you are using one of our SDKs we'll create our request object and convert it to JSON. Your application code can then pass the JSON string to the client-side library. If you're integrating directly, your application can build the HTTP POST itself.

    Note: Your shared secret should always remain on the server-side and must not be exposed to the public.

    Step 2 - Set up your client

    HTML/JS

    To integrate with our server-side SDK, you can use our JavaScript library available to download on GitHub. This interfaces with the server-side SDK of your choice and generates the payment form on your website or in your application. You can choose to render the payment form using your own embedded iFrame, as a Lightbox or perform a full-page redirect.

    In Lightbox mode, for example, the JS library does all the work of creating the overlay, opening the iFrame, displaying the HPP and finally grabbing the response to be sent to the server-side SDK. In mobile browsers the HPP is opened in a new tab.

    Note: The sample code below is given as an example, you may need to modify it in order to suit your particular needs.



    EMBEDDED

     

    <script src="https://code.jquery.com/jquery-3.5.0.js"></script>
<script src="rxp-hpp.js"></script>
<script>
  $(document).ready(function() {
    $.getJSON("sdkRequestEndpoint", function(jsonFromRequestEndpoint) {
      RealexHpp.setHppUrl("https://pay.sandbox.realexpayments.com/pay");
      RealexHpp.embedded.init("payButtonId", "iframeId", "responseEndpoint", jsonFromRequestEndpoint);
      if (window.addEventListener) {
        window.addEventListener('message', receiveMessage, false);
      } else {
        window.attachEvent('message', receiveMessage);
      }
    });
  });
</script>



    Notes on the Sample Code

    payButtonId This will be the ID of the button used to launch the HPP.
    iframeId The ID of the iFrame to load the HPP into.
    responseEndpoint The URL to which the JSON response from the HPP will be posted.
    jsonFromRequestEndpoint The JSON output from the HPP server-side SDK. This must be a JavaScript object, not a string.
    RealexHpp.init() Must only be called when the page DOM is fully loaded.

    HPP Example (Embedded iFrame)
    HPP Embedded
    Android

    In order to utilize the HPP in-app you can use our Android library. It can be installed using Maven or Gradle and it's also available to download on GitHub For more information on installation, please refer to the Libraries & SDKs section.

    The library interfaces with the server-side SDK of your choice; processing the request, presenting the payment form and handling the transaction outcome.

    The library is compatible with Android SDK 19+ and Android version 4.4+.

    The sample code below is given as an example, you may need to modify it in order to suit your particular needs.


    Instantiate

    To instantiate the HPPManager do the following:

    HPPManager hppManager = new HPPManager();

    Integrate With Your Server

    The HPPManager requires three server URLs.

    • Request Producer URL: utilizing one of the HPP server-side SDKs, this URL creates the necessary request JSON as outlined in Step 1 above.
    • HPP URL: the location to send the request. The default value for live transactions is https://pay.realexpayments.com/pay
    • Response Consumer URL: utilizing one of the server-side SDKs, this endpoint takes the response received back from the HPP, decodes it and checks the validity of the hash. See the sample code for Consume HPP Response JSON below.

     

    The three URLs can be set in the following way:

    hppManager.setHppRequestProducerURL("https://myserver.com/hppRequestProducer");
hppManager.setHppURL("https://pay.sandbox.realexpayments.com/pay");
hppManager.setHppResponseConsumerURL("https://myserver.com/hppResponseConsumer");

    Implement HPPManagerListener In Your Activity

    There are three possible outcomes from the HPP interaction:

    • It concluded successfully
    • It failed with an error
    • It was cancelled by the user (for example they tap the back action)

     

    Note that these are independent of the outcome of the transaction (whether it was authorized successfully or not), what we're referring to here is the Android library's actual communication with the HPP. You can implement the following methods specified in HPPManagerListener to receive back the result from the HPPManager:

    @Override public void hppManagerCompletedWithResult(ConsumerResponse consumerResponse) { /* success */ }
@Override public void hppManagerFailedWithError(HPPError error) { /* something went wrong */}
@Override public void hppManagerCancelled() { /* operation was canceled */ }

    Present The Payment Form

    Insert the HPPManager fragment into your activity as follows. When executing this code HPPManager will process the given parameters, get the request from the server, send the encoded request to HPP and present the form received back.

    Fragment hppManagerFragment = hppManager.newInstance();
getFragmentManager()
        .beginTransaction()
        .add(R.id.container,hppManagerFragment)
        .commit();

    Android in-app example

    You can style the HPP using templates to maintain the look and feel of your app. For more information on how to do this and to download some sample templates, please see our Customization guide.

    iOS

    In order to utilize the HPP in-app you can use our iOS HPP library. It can be installed using Cocoapods and it's also available to download on GitHub For more information on installation, please refer to the Libraries & SDKs page.

    The library interfaces with the server-side SDK of your choice; processing the request, presenting the payment form and handling the transaction outcome.

    The library is compatible with Xcode 7.1.1+ | iOS 8.0+.
    The sample code below is given as an example, you may need to modify it in order to suit your particular needs.


    Instantiate

    To instantiate the HPPManager do the following:

    let hppManager = HPPManager();

    Integrate With Your Server

    The HPPManager requires three server URLs.

    • Request Producer URL: utilizing one of the HPP server-side SDKs, this URL creates the necessary request JSON as outlined in Step 1 above.
    • HPP URL: the location to send the request. The default for live transactions is {{ hpp_url }}
    • Response Consumer URL: utilizing one of the server-side SDKs, this endpoint takes the response received back from the HPP, decodes it and checks the validity of the hash. See the sample code for Consume HPP Response JSON below.

     

    The three URLs can be set in the following way:

    hppManager.HPPRequestProducerURL = NSURL(string: "https://myserver.com/hppRequestProducer");
hppManager.HPPURL = NSURL(string: "https://pay.realexpayments.com/pay");
hppManager.HPPResponseConsumerURL = NSURL(string: "https://myserver.com/hppResponseConsumer");

    Set Delegate

    Next you set the object which will act as the delegate for the HPPManager. The delegate should implement the HPPManagerDelegate protocol and so will receive the response from the HPPManager.

    hppManager.delegate = self;

    Delegate Callbacks

    There are three possible outcomes from the HPP interaction

    • It concluded successfully - this returns the decoded JSON from HPP, parsed as a native Dictionary of name/value pairs.
    • It failed with an error - this returns an object of the NSError Class, you can access properties such as code and localizedDescription for more details on the error.
    • It was cancelled by the user (for example the customer tapped Cancel).

     

    Note that these are independent of the outcome of the transaction (whether it was authorized successfully or not), what we're referring to here is the iOS library's actual communication with the HPP. The HPPManager's delegate should implement the following three functions to receive back the result from the HPPManager.

    func HPPManagerCompletedWithResult(result: Dictionary <String, String>);
func HPPManagerFailedWithError(error: NSError?);
func HPPManagerCancelled();

    Present Payment Form

    Using the presentViewInViewController() method the HPPManager will process the given parameters, get the request from the server, send the encoded request to HPP and present the form received back.

    hppManager.presentViewInViewController(self);

    iOS in-app example

    You can style the HPP using templates to maintain the look and feel of your app. For more information on how to do this and to download some sample templates, please see our Customization guide.

     

    Step 3 - Process HPP Response


    On the server-side, setup your response endpoint to take in the response JSON and create the HPP response object. This will contain all the transaction response values you need to update your application. If you're using full-page redirect the response will be a standard HTTP POST.

    The response from HPP will contain a hashed string (SHA1HASH field) made up of key transaction variables, including the Order ID, Result Code and Timestamp. The SDK will construct and check the hash to ensure the response hasn't been tampered with. It will throw an exception if what it constructs doesn't match the SHA1HASH returned in the response.

    The Timestamp returned in the response will be identical to the one sent in the request JSON. This, combined with the Order ID and other transaction variables, can be used to definitively link the response received with the transaction request and order created in your application. You should also check the other transaction variables, for example the Amount, against what was stored in your application at the time the request JSON was sent.

    A 111 result code indicates that the Issuer requires Strong Customer Authentication (SCA) for a transaction. In order to avoid this outcome, please ensure you enable 3D Secure 2 on the HPP.
