Currently we have custom code set to move items from one list to another using a bootstrap/alpaca form button in conjunction with JS. The customer wants to keep the UI (Alpaca Form) to complete the same functionality, but leverage Nintex workflow instead of JS to get the work done. It would be a very simple workflow to complete the process, but not clear if its possible to trigger the workflow via the CSS/Bootstrap/Alpaca buttons. Thank you for any and all info!
From your Alpaca form you can create an item on a SharePoint list ( with a REST Call ), so a workflow on that list can be started when an item is created.
if you want to start workflow directly from JS, have a look on this Vadim Tabakman's blog
