Use ServiceNow forms for outbound post calls

I am trying to use the servicenow form field to populate the values of an external application with a create api call.
My attempt was to create a servicenow application with studio. In studio, I clicked " *Create Application and I was able to add the api endpoint, and I ran the test to make a post call to the api. And when I went to the api application, the value was there; so that’s great! Now I’m trying to add a form to the servicenow application, so that the values added to the fields will not only show in servicenow, but also to the api. Is this possible, and how do I go about doing this?

Hello, are you using your servicenow application on a device running balenaOS?
