Geoserver WPS Execute Request

Question

I have a Geoserver that I am trying to return a GeoJSON with my WPS with a web link but I am unsure how to.

The tutorial on the Geoserver website says to do a curl. I'm sure Geoserver can do this because it has a demo WPS builder and returns what I need. I'm using Leaflet to visualize the returned web link so it'd be nice to have it dynamically pulling rather than pointing to a uploaded file.

This is what I have. Any help is greatly appreciated.

It may be that you need to use a POST request like

curl -v -u admin:geoserver -X POST -H "Content-type: xml" \
-d @test.xml \
http://localhost:4080/geoserver/wps\?request\=Execute\&service\=WPS\&version\=1.0.0

(obviously all on one line without \ if you use windows)

works for me where test.xml contains:
