This command queries the JSONPlaceholder APIs posts endpoint and returns a list of post resources. The Uri parameter is what tells Invoke-RestMethod where the endpoint is.įor example, run the command below. To send a simple GET request to a REST API endpoint, you’ll only need one parameter, Uri. Invoke-RestMethod can do a lot, but you need to understand the basics first. Let’s start things off with the simplest example out there querying a REST API with a GET request. Without further ado, open your PowerShell console and/or code editor and let’s get started! Retrieving Data via a Simple GET request This tutorial uses a Windows 10 machine and PowerShell 7.1. ![]() If you’d like to follow along with the many demos in this tutorial, be sure that you have: The Invoke-RestMethod cmdlet is the PowerShell cmdlet to interact with REST APIs!
