Liquid ids for variant ID, segment ID, template id

Hello - 

I need to drive traffic to a third party (impact). I have a canvas set up and I want to measure conversion based on the variant ID, the segment id and the email template ID.  The conversion is tracked via impact.

I was hoping I could dynamically add these to the url like so:
http://whatever.co/?variant_id={{variant_id}}&segment_id={{segment_id}}&template_id={{template_id}}

or

http://whatever.co/?sid1={{variant_id}}&sid2={{segment_id}}&sid3={{template_id}}

I thought that liquid variables may do this, but every test I run, the liquid parameters are excluded.

Is there any way to make this work?

Thank you
