Azure Logic App: Utilizing Cognitive Service Computer Vision and Text Analytics API

Azure Logic Apps

Logic App is a cloud-based service. It allows us to react to an event in one service (such as SharePoint online) and do something with the data from that event in another Service (such as Twitter). It makes it practical and simple for business processes. The users build workflows that automatically perform some business tasks and processes across applications and services. We can connect our business-critical apps and services with Azure Logic Apps, automating our workflows without writing a single line of code.
