The Content Server API has a forms API defined for so-called Alpacea forms. It looks like this API, just like the nodes API allows for the creation and update of Content Server objects. Some questions: 1) When would one use forms instead of nodes, 2) is there an API for accessing Content Server forms (i.e. WebForms), and 3) if there is no such API, is this something on the roadmap? For a client, I ended up building my own REST API to get details about Form templates, and recently added a form data fetch, update, and submit mechanisms. I may productize these if there is currently nothing on the roadmap about Content Server Web Forms.
