REST API calls with Invoke-RestMethod in PowerShell - Mini Project: Build & Apply

REST API calls with Invoke-RestMethod

📖 Scenario: You are working with a public REST API that provides information about users. You want to fetch data from this API and process it in PowerShell.

🎯 Goal: Build a PowerShell script that calls a REST API using Invoke-RestMethod, filters the results based on a condition, and displays the filtered data.

📋 What You'll Learn

Create a variable with the API URL

Create a variable for the minimum user ID to filter

Use Invoke-RestMethod to get data from the API

Filter users with IDs greater than or equal to the minimum ID

Print the filtered users' names and IDs

💡 Why This Matters

🌍 Real World

Calling REST APIs is common when working with web services to get or send data automatically.

💼 Career

Many IT and automation jobs require scripting to interact with APIs for monitoring, reporting, or integrating systems.

1

Set the API URL

Create a variable called apiUrl and set it to the string "https://jsonplaceholder.typicode.com/users".

PowerShell

# Create a variable called apiUrl with the API URL
# Your code here

Need a hint?

Use $apiUrl = "https://jsonplaceholder.typicode.com/users" to store the URL.

2

Set the minimum user ID filter

Create a variable called minUserId and set it to the number 5.

PowerShell

$apiUrl = "https://jsonplaceholder.typicode.com/users"
# Create a variable called minUserId and set it to 5
# Your code here

Need a hint?

Use $minUserId = 5 to set the filter value.

3

Fetch and filter users

Use Invoke-RestMethod with $apiUrl to get the users and store them in a variable called users. Then create a variable called filteredUsers that contains only users with id greater than or equal to $minUserId.

PowerShell

$apiUrl = "https://jsonplaceholder.typicode.com/users"
$minUserId = 5
# Use Invoke-RestMethod to get users and store in $users
# Filter users with id >= $minUserId into $filteredUsers
# Your code here

Need a hint?

Use $users = Invoke-RestMethod -Uri $apiUrl to get data.
Use Where-Object { $_.id -ge $minUserId } to filter.

4

Display filtered users

Use a foreach loop to print each user's id and name from $filteredUsers in the format: User ID: [id], Name: [name].

PowerShell

$apiUrl = "https://jsonplaceholder.typicode.com/users"
$minUserId = 5
$users = Invoke-RestMethod -Uri $apiUrl
$filteredUsers = $users | Where-Object { $_.id -ge $minUserId }
# Print each user's id and name from $filteredUsers
# Your code here

Need a hint?

Use foreach ($user in $filteredUsers) { Write-Output "User ID: $($user.id), Name: $($user.name)" } to print.
