Pay Invoice Link
From Adjutant Wiki
The Pay Invoice Link is used for customers using Heartland integration. The generated link can be sent to your customers for an invoice to allow your customer to pay online. The link can be generated and emailed out with the along with the invoice using the instructions below.
First, a special token needs to be added to the Etemplate Lower List Values rule formatted with the Name = "PayInvoiceURL" and the Code = "~*PAYINVOICEURL2*~. This will put the special token as an option in the email template.
Next, the Web URL needs to be filled out with the correct link. Text 1 should be called ADJ2PAYINV. The Text 2 URL should be your 20/20 URL with /payinvoice_S.htm at the end.
Now you should be able to add the special token to the PRINTINV email template, which is the default template used when emailing an invoice. The special token will be in the "Extras" list from the drop down at the bottom of the screen. It should appear like the screenshot.
The link will send the user to a page where they can input credit card information and pay the invoice. The payer will receive a confirmation email and the invoice balance will immediately update.
