You have downloaded the ePay plugin for payments in ticketmaster. 
We will describe here how to use this properly.

•  Install the plugin like any other plugin and go to the plugin manager.
• Open the plugin and setting the parameter.

We need the following things done, first we need to know the merchant number:

In the setting of the payment system you can find the merchant number for your account. You can see the blue paint, there is your merchantnumber.
fill the number at the parameters in the first inputbox. 

Unique Order ID: We are using our own unique orderid. so change the dropdown the same way we did.
MD5 Security Check: Choose a random number or word or a combination like we did. It's being used as security.

So we have the merchant number now, the MD5 Security ID can be filled now. Let's take a look at the others.

• Save this and go to the Message Center of Ticketmaster and add 2 new messages.
  Enter the EID numbers in the Template on Failure and Template on Success inputboxes. 
• Do you want to receive a message by SMS when payments came in? Check to "Yes" (Note: this will cost money)
• Choose the payment type, set to "Standard Payment" for all payments.
• Set the desired currency
• Set the desired Language.
• Choose a nice sentence for the info at checkout:
  Example: Choosing ePay as a secure provider, click checkout and wait for the popup. After your payment this page will refresh automatically. 

Your payment/checkout will look like this:
