From what I have deduced (of course there's no documentation) the following are the "Asset Reservation" tags that can be used in emails sent in regard to reservations:
- <first_name>
- <last_name>
- <login_id>
- <login_url>
- <helpdesk_contact_info>
- <helpdesk_name>
- <due_date>
- <asset_list>
Only those "tags" highlighted above are actually listed however in the primary "tags" documentation here:
So that leads me to doubt the documentation is actually complete or accurate - it even lists the <last_name> tag twice which supports my claim about inaccuracy/incompleteness:

That being said, what I REALLY want to be able to do in my "Overdue Assets Message" template is to list the Reservation Number somewhere in the email:

You can include things like "Due Date" and the "Asset List" which looks great on the emails and it's really helpful to drive the right behavior, which is to return the assets:

But does anyone happen to know (or have a behind the scenes "in" at SolarWinds) who can confirm if there is a "hidden" tag that can be used like <asset_resID> or something else? Having this would really come in clutch right now. I wish there was time that the developers could put in to make MORE tags...they're super useful!
