I have a business requirement where I have to implement a wizard based registration form I.e. step1, step2, step3 etc and after last screen I would like to save the data and create an approval request. The request should go to approval user(Single or Multi level approval)

In addition I would like this process to be accessible via RESTful API so that it can be consumed via a different web/mobile application.

please assist or any relevant tutorial available for similar business scenario.

thanks
