Integrated workflow apps for SharePoint Online allows the creation workflows that can be attached to list or library in Host Web. Though this feature has been available in SharePoint Online for some time there is no tooling support for this Visual Studio 2013. To create an integrated workflow app in Visual Studio 2013 we will have to perform a workaround by editing the workflowmanifest.xml manually and setting the Integrated App value to true. This process is explained clearly in Andrew Connell’s article
With the release of Visual Studio 2015 Integrated Workflow Apps can be created from the IDE without requiring manual edit of XML files. Below are the steps to create an integrated workflow app in Visual Studio 2015
- Create SharePoint Hosted App and target it to SharePoint Online.
- Add a workflow item to the SharePoint App project. The app can become an integrated workflow app only after a workflow has been added to it.
- That’s all you need to do. Now after the app is deployed to a SharePoint online site you will be able to add a workflow to a list or library in the host web.
