How to catch multiple data fields from a receiving mailhook

Hi,

I am having difficulties to add multiple data fields in a single mailhook. I use an Automation in my Tadabase(dot).io enviroment, where Make functions as an intermediary between Tadabase and Sendgrid.

I need to add both E-mail, Name, Adress & Place in the mailhook, and add this is a dynamic variable in the Sendgrid template.
I know how it works on the Sendgrid end in Make (work with keys& values), but I don;t know where to add this data in the mailhook in such a way that Make can extract these values and assign these to the right variables for the scenario.
Check the screenshot for the setup of the mailhook.

Question: Where do I need to add the fields (e.g. body content) but how do I extract this in Make then?
