Programming¶

This section contains 3 parts:

• Generate redirect URL - describes how to generate the redirect URL
• Back URL - describes how to handle the returned consumer
• PSC URL - describes how to capture the payment information

Generate redirect URL¶

This URL will be used to redirect the consumer to GlobalCollect's payment pages.

Step-by-Step:

1. Prepare the following parameters:
   • connection - an established database connection
   • orderId - the unique order ID, 20 alphanumeric characters
   • amount - the order amount in cents, and integer values only
2. Pass the above parameters to the following interface:
   

   String redirectUrl = PaymentUtils.genRedirectPaymentUrl(connection, orderId, amount);
   

3. Insert the order ID information into session.
4. Redirect the consumer to the generated URL using JavaScript or HttpServletResponse.sendRedirect.

Back URL¶

The back URL acts as receipt URL also. This is where the consumer will be redirected to after completed the payment.

As GlobalCollect will not forward payment information to the URL, one has to obtain the order details via the active session. The following guide assumes the order ID is stored in the session.

Step-by-Step:

1. Prepare the following parameters:
   • connection - an established database connection
   • orderId - the unique order ID, 20 alphanumeric characters
2. Pass the above parameters to the following interface:
   

   String orderId = (String) session.getAttribute("test_ord_id");
   PaymentUtils.persistPaymentStatusForReceipt(connection, orderId);
   

3. And then, one can obtain the payment status in the interface table (see Table Name);

PSC URL¶

For every payment transaction with the status 500 and above, GlobalCollect will post the payment information to the PSC URL.

Step-by-Step:

1. Prepare the following parameters:
   • connection - an established database connection
   • request - the HttpServletRequest object
2. Pass the above parameters to:
   

   PaymentUtils.persistPaymentStatusForPsc(dataBean.getConnection(), request);
   

3. [Important] The PSC must not contains any HTML element except a 'OK' string e.g.,
   

   out.print("OK");
   

FAQ¶

PSC:

• GlobalCollect post the payment result within 2 minutes after completed payment
• The PSC URL must be a HTTPS URL
• Only those payment result with status 500 or above will be posted to PSC URL.
• The number of retry attempt is 10 and retry interval is 2 minutes. When reached the maximum retry attempt, the PSC posting will be disabled.
