Pipeline POST Body

What I currently have setup, is when a record is created, it creates a user name at my 3rd party service.

Here's a partial of what's in the body:

&clientName={{a.company_name}}&userName={{a.company_name}}&firstName={{a.company_name}}

What I want for &userName, is to have a QB company_name field, plus static word "Admin"

So I tried:
&clientName={{a.company_name}}&userName={{a.company_name}} Admin&firstName={{a.company_name}}

But it's not adding that word "Admin", it completely ignores it.

I've never worked with JSON, and this was my very first time, and it all works great, I just can't add specific word to combine with an existing field name.
