If i’m making a registeration form that requires a key.  The docs arent that clear if there should be a “key” keyword in the URL or not.  Should my registration template url be:

www.example.com/template_group/register_template/key/{key}

or

www.example.com/templategroup/register_template/{key}

The “key” portion is only a “trigger” in the URL… not a template

so my urls should have the “key” trigger word and then the key value in them? (eg www.example.com/templategroup/template/key/ZXY123), rather than just having the key value with no trigger word.

Correct
