To activate the AsiaPay module in WHMCS, navigate to Setup > Payments > Payment Gateways and choose AsiaPay from the "All Payment Gateways" tab.
Once activated, you can then customize the name to something more friendly such as "Credit Card". To complete setup, you would then enter your credentials in the appropriate boxes.
Secure Hash Key
We recommend using the Secure Hash Key to protect against unauthorized callbacks.
To setup a Secure Hash Key within your AsiaPay account, you must contact the PayDollar Service Department (email@example.com) to request the Secure Hash function be enabled for your merchant account. Once enabled, you can retrieve the hash from within the Merchant Administration Interface by navigating to Profile > Payment Information.
Once you have obtained your Secure Hash, enter it into the "Secure Hash Key" field within the WHMCS Payment Gateway Configuration area for the AsiaPay module.
