While implementing an Oracle Process Cloud Service PoC we had the requirement to allow users to start an instance using a form in their custom mobile application and also using the workspace.
We have a 'Form Start Event' so users can start the instance thought the workspace. We also added a 'Message Start Event' in order to publish it as a web service.
Having that process deployed, if we head to 'Deployed Applications' in workspace main page.
We can see the web services exposed.
