Microsoft Flow is a Cloud based automation service available as a component in Office 365, that enables us to build the workflow process across different applications / services. There are n number of Microsoft and Third party applications can associate with the Flow to develop the seamless process across different application without moving away.

Though it has lot of actions, still Flow has limited services and that didn’t allow us to achieve some functionalities. To overcome some of the limited areas, recently Microsoft added a new action to the Microsoft Flow for SharePoint. That enables us to send SharePoint REST API requests to achieve the most of the SharePoint functionalities using the action called Send an HTTP request to SharePoint

Follow the below steps to use the Send an HTTP request to SharePoint action to create a folder in SharePoint List.

Scenario: We have two lists called Employee List and Employee Contents List. Whenever a new item is created in Employee List, a folder will be created in Employee Contents List in the same name of title in Employee List.

  1. Select Flow from Office 365 App Launcher, to navigate to Microsoft Flow page
  2. In the Flow site, click Create from Blank button to initiate the Flow creation,
