How To Get All The Lists Using HTTP Web Service In SharePoint Designer 2013 Workflow

Introduction

In SharePoint 2013 Workflows, you call a Web Service using a new action, which was introduced in SharePoint 2013 named Call HTTP Web Service. This action is flexible and allows you to make the simple calls to a Web Service easily, or, if needed, you can create more complex calls, using HTTP verbs as well as allowing you to add HTTP headers.

The Call HTTP Web Service action lets you specify any of the several request methods, including GET, PUT, POST and DELETE. This lets you tell the Web Services, specifically RESTful services what is to be done on the service that you’ve specified with the URL property on the activity. For more details, please refer to this link.
