Programming Guide¶
This guide describes how to make use of the NMI APIs for payment related transaction and it consists of 2 main parts:- Step-By-Step - describes the
- API Reference - the detailed description of all the APIs mentioned in Step-By-Step
The demo application can be found here:
Step-By-Step¶
Before begin, install the following libraries into your development environment (remove the old versions if exists): Steps:- To get the form URL, pass the required parameters to getFormActionUrl method.
- Use the form URL (in which obtained in the previous step) to construct the payment form with the following
input
elements:- billing-cc-number
- billing-cc-exp
- cvv
- billing-first-name
- er
Generate the form action URL¶
Generates the form
action URL which is needed in the self-hosted payment form.
Method Signature:
public static String getFormActionUrl(String orderId, String orderDescription, BigDecimal orderAmount, String returnUrl)
Input Parameters¶
- orderId - the unique ID for the order
- orderDescription - a simple description of the order
- orderAmount - the settlement amount of the order in 2 decimal places, e.g. 12.34
- returnUrl - the receipt URL
Output Parameters¶
Returns a form
action URL
Code Snippets¶
String orderId = request.getParameter("order-id"); String orderDescription = request.getParameter("order-description"); BigDecimal orderAmount = new BigDecimal(request.getParameter("order-amount")); String returnUrl = request.getParameter("return-url"); String formUrl = PaymentUtils.getFormActionUrl(orderId, orderDescription, orderAmount, returnUrl);
Payment Status Callback¶
Queries the payment status using the token ID
that returned by NMI. After obtained the payment status, update the particular record in the Interface table.
Important: This method is supposed to be placed and invoked in the very beginning of the receipt page, (a.k.a. the returnUrl
that specified in Generate form action URL).
Method Signature:
public static String queryAndPersistPaymentStatus(Connection dbConnection, HttpServletRequest servletRequest)
Input Parameters¶
- dbConnection - an established database connection
- servletRequest -
HttpServletRequest
object which will be used to obtain the request parameter,token-id
Output Parameters¶
the order ID
that used in the particular payment transaction
Code Snippets¶
Connection connection = createDbConnection("java:/DB2DS_USA"); String orderId = ""; try { orderId = PaymentUtils.queryAndPersistPaymentStatus(connection, request); } finally { if (connection != null) { connection.close(); } }
