If you have multiple terminal ID’s- Using the dropdown terminal menu on the top right select Internet.
Step 2 - Set Fraud Filters
You will be required to set fraud filters (Daily, Hourly, Hourly velocity by IP address) prior to being able to create a buy button.
These are fraud prevention rules (ie. How many transactions are allowed per hour/day etc. through this terminal ID.)
Step 3- Customizing Hosted Payment Page
When cardholders click on your button or link, they are redirected to the Converge hosted payment page to enter in their information. Depending on the information you want to capture, you can customize what is displayed on the payment page. The payment page must be setup PRIOR to creating the button /link. See How To: Customize Converge Hosted Payment Page (HPP) to configure your payment page.

Step 5 - Configuring the Buy Button / Link
Set Pricing Option - This can either be a set amount (Set fixed price) or an open amount that the cardholder enters (Allow buyer to input price).

Set Transaction Type - (i.e. Auth Only, Sale, Tokenize Card) depending on how you will be using the link/button.

Step 7 - Generate the button / Link
Click GENERATE BUTTON - the HTML code will populate in the box.
If you chose hyperlink: copy the text that is in between the quotations only and send it out it in your emails. [Tip: create a dedicated email signature with the words click to pay and insert hyperlink so when your customers click those words it will direct them to your payment page]
If you chose button: paste the HTML wherever you need it to be on your website by accessing your website's source code.
If you make any changes to settings after you generate the code, you will need to generate the button again to get the most recent link.

Step 8 - Website Review
Whenever the cardholder is inputting their own credit card on a payment page this is considered eCommerce transactions and the payment page must be reviewed by a website review compliance team to ensure it is in compliance with card brand regulations. The main requirements are to have your business name and contact information displayed on the payment page. The final step, is to send us your link to have reviewed.
