Sending data from Shopify to FB CAPI

I have a scenario set to take information from a Shopify purchase webhook and send it to FB Conversions API but there are two specific pieces of information that I can’t seem to figure out how to pass along.

The first is the user agent. In order for me to send browser IP to CAPI, I have to include the user agent. Shopify sends it, but Make doesn’t let me use it as one of the parameters… User agent is nowhere to be found (see attached).

The second is fbclid. This is usually passed on through the URL (if it exists), how can I parse this info (if it’s there) and send it to CAPI?

These two things will greatly increase the reliability of my pixel data.
