• Click Save Changes
• On the next page, copy the Website HTML code and save it in an HTML file, say paypalqlm.html, on your desktop or website

Testing the Buy Now button

• Open paypalqlm.html and click the Buy Now button
• Follow the steps required to place this test order.
• Within a 2-5 minutes, check the QLM Management Console / Manage Keys tab to confirm that a new license was created
• If no license is created, check the QLM Event Log to diagnose the issue. You can increase the logging level from Manage Keys / Sites / Server Properties / PayPal / paypalLoggingLevel. The highest level of logging is 15. You should always restore the loggingLevel to its default value of 3 when done.

Email Template

You can customize the email template to use when sending an email to the customer. To customize the email template, add the is_emailtemplate argument as shown above. The email template can be created from the QLM Management Console / Manage Keys / Email Templates.

The email template can contain any PayPal variable such as %payer_email% or %ProductName%. 

As of QLM 9.0.16228.1, the is_emailtemplate argument can be used with templates created in the QLM Management Console / Templates Editor. For example, if you create a template in the QLM Templates Editor called NewOrder, set the is_template as follows: &is_emailtemplate=NewOrder

QLM 9.0.16228.1+ includes 4 Paypal specific templates: Paypal.NewOrder, Paypal.NewSubscription, PayPal.RenewSubscription and Paypal.CancelSubscription.
