How To Integrate¶

To integrate with the MiGS, one must:

• Redirect the customer to the MiGS payment page
• Capture the payment response which returned by MiGS, after the customer submitted the payment

One could refer to the following page for demo:

http://192.168.2.68/ecosway/migs-sample/migs_test.html

To generate the redirect URL:

• Example:
  

  String redirectUrl = MigsPaymentUtils.genRedirectUrl(MigsCurrency.HKD,
                  locale,
                  orderNo,
                  amount, 
                  returnUrl);
  
  

  • redirectUrl - redirect the user/customer to this URL to make payment
  • MigsCurrency.HKD - the currency of the payment
  • locale - the display language of the MiGS payment page, e.g. en_US
    • English - en, en_US
    • Simplified Chinese - zh_CN
    • Traditional Chinese - zh_TW
  • orderNo - the unique order number (1-40 alphanumeric)
  • amount - the amount of the payment in cents (1-12 numeric)
  • returnUrl - MiGS will redirect the user to this page after made the payment (1-255 alphanumeric)

To capture the payment:

• Example:
  

  String orderNo = MigsPaymentUtils.persistPaymentStatus(connection, request);
  
  

  • orderNo - the order number of the payment
  • connection - an established database connection where the payment interface table resides, e.g. MIGS_INTERFACE
  • request - the HTTPServletRequest object
• Refer to the STATUS column in the interface table to check if the payment is success
  • YES - success
  • NO - failed
    • refer to ERROR_MSG column in the interface table for more details
