Approval workflow with Azure Logic Apps, Office 365 and SharePoint
Connect different software as a service providers with SharePoint through Azure Logic Apps. I was speaker at the local Azure Bootcamp (2016) in Sofia and after I decided to record short video on one of the demos I presented on the event. Of course it has relation to SharePoint and shows how we can connect it to different SaaS providers in minutes by using drag and drop first class designer directly in the Azure portal instead of building custom code.
You should consider Azure Logic Apps for future development because It makes it easier to build web, mobile, and integration apps. It is workflow driven system where actions and conditions can be nicely combined to form flow of a business process.
Build in SaaS connectors are provided to many of the Microsoft technologies including the Office 365 stack, Microsoft SQL, OneDive, Dynamics and BizTalk services as well as providers like Salesforce, Dropbox, SAP, Github, Facebook, Tweeter, Google Drive and many others are added even now.
For expert scenarios a Logic App can be extended by custom code trough API APP or Azure Functions created with your preferred programming language (C#, Node.js, Python or other).
