When sending Marketing Email through Workflows, this worked for me:
I just added the line below to the URL box. For Contact properties it may work simpler as “contact.firstname”, but for other objects it requires the HTML personalization token invoke.
{{ personalization_token(‘object.property’, ‘’) }}
Note: if you are using Ticket tokens, the workflow that sends the email must be a Ticket workflow. You won’t be able to add the template to the workflow if it contains personalization tokens for different objects.
