I'm using the Pardot REST API to send emails documented here:
http://developer.pardot.com/kb/api-version-4/emails/#sending-one-to-one-emails
It's all great but I would like to set custom fields in my email template for example like:
{EmailConfirmURL}
And populate them through the REST API, so I could do:
http://email-send-url.com?EmailConfirmURL=myvalue
Is that possible in Pardot?
