How to use angular form with camunda

Hi, I have an application workflow and the first process of that BPM is to create a request from the web page which is developed from angular. As in the below diagram.


There are several fields form in the creation request. How do i add that form data to my BPM and is there anything that i need to do in my front end form?

@dushan_chain1 maybe the following blog post will help

that blog helped me but what should I add for the “variable” in that angular solution and do i need to define teh form in my BPM as well ?
