I have a solution in VS2012 with a SharePoint 2013 sandboxed project. I have created some custom workflows in 2013.
What I really need to do is to have an approval workflow to publish content, and send out an email when a new document is approved.
My first thought was to use the OOB approval 2010 workflow and use an event receiver on the list. When an item becomes approved, I would send out an email, but I'm unable to send emails programmatically in SharePoint online.
My second thought was to recreate the workflow in 2013, since I know I can send emails out that way, but it looks like the activities related to content approval were removed for 2013 workflows. I can try and do the approvals via rest calls, but my concern was that my workflow will fire every time the item in the list changes (even if it's not a publish), so I will have to check (in the workflow) if the item is being published or not. This will cause the workflow history for the items to become pretty useless as it will be filled with mostly white noise. Also, as far as I can tell, the checkbox when you create an association for "Start this workflow to approve publishing a major version of an item." does not apply to 2013 workflows.
I believe my best answer at this time would be to create a custom 2010 workflow, but I don't see how I can do that from inside VS2012. Can anyone help me (or maybe suggestion another alternative to achieving my goal?)
