Java SDK


Check out our GitHub repository (opens in a new tab) to download this SDK.

This Java SDK provides an easy method to integrate with the payment gateway.

  • The file contains the main body of the SDK.


  • The SDK requires the following prerequisites to be met in order to function correctly:
    • For convenience the following Java libraries have been included for easier set up:
    • commons-cli-1,4
    • commons-codec-1.13
    • commons-io-2.8.0
    • commons-lang3-3.11
    • commons-text-1.9
    • hamcrest-2.2
    • httpclient5-5.0.2
    • httpclient5-cache-5.0.2
    • httpclient5-fluent-5.0.2
    • httpclient5-testing-5.0.2
    • httpclient5-win-5.0.2
    • httpcore5-5.0.2
    • httpcore5-h2-5.0.2
    • httpcore5-reactive-5.0.2
    • httpcore5-testing-5.0.2
    • jna-5.2.0
    • jna-platform-5.2.0
    • junit-4.13
    • reactive-streams-1.0.2
    • rxjava-2.2.8
    • slf4j-api-1.7.25

Please note that we can only offer support for the SDK itself. While every effort has been made to ensure the sample code is complete and bug free, it is only a guide and should not be used in a production environment.

Using the Gateway SDK

Require the gateway SDK into your project

    import java.util.HashMap;
    import com.paymentnetwork.Gateway;

Instantiate the Gateway object

        var gateway = new Gateway("merchantid", "secretkey", "", "", null);

Once your SDK has been required. You create your request array, for example:

	HashMap<String, String> params = new HashMap<String, String>();
	params.put("merchantID", "100856");
	params.put("action", "SALE");
	params.put("type", "1");
	params.put("transactionUnique", uniqid);
	params.put("countryCode", "826");
	params.put("currencyCode", "826");
	params.put("amount", "1001");
	params.put("cardNumber", "4012001037141112");
	params.put("cardExpiryMonth", "12");
	params.put("cardExpiryYear", "20");
	params.put("cardCVV", "083");
	params.put("customerName", "Test Customer");
	params.put("customerEmail", "");
	params.put("customerAddress", "16 Test Street");
	params.put("customerPostCode", "TE15 5ST");
	params.put("orderRef", "Test purchase");
	// The following fields are mandatory for 3DS v2 direct integrations
	params.put("remoteAddress", "");
	params.put("merchantCategoryCode", "5411");
	params.put("threeDSVersion", "2");
	params.put("threeDSRedirectURL", ""); // PLACEHOLDER

NB: This is a sample request. The gateway features many more options. Please see our PDF integration guide (opens in a new tab) for more details.

Then, depending on your integration method, you'd either call:

	var options = new HashMap<String, String>();
	var gatewayResponse = gTest.directRequest(params, options);


	var options = new HashMap<String, String>();
	var gatewayResponse = gateway.hostedRequest(params, options);

And then handle the response received from the gateway as per our integration guides.
