Why webhooks push notifications in Rest API - See It in Action

Why Webhooks Push Notifications

📖 Scenario: Imagine you run an online store. You want to know immediately when a customer places an order so you can start packing it. Instead of checking the website all the time, you use a webhook to get notified instantly.

🎯 Goal: Build a simple program that shows how webhooks push notifications to your system when an event happens, like a new order.

📋 What You'll Learn

Create a dictionary called event_data with keys 'event' and 'order_id' and values 'order_placed' and 12345

Create a variable called webhook_url and set it to 'https://example.com/webhook'

Write a function called send_webhook_notification that takes url and data as parameters and prints a message showing the URL and data sent

Call the function send_webhook_notification with webhook_url and event_data

Print the message exactly as: Sending webhook to https://example.com/webhook with data {'event': 'order_placed', 'order_id': 12345}

💡 Why This Matters

🌍 Real World

Webhooks are used in many apps to notify other systems instantly when something important happens, like a new order, a payment, or a message.

💼 Career

Understanding webhooks is important for developers working with APIs, integrations, and real-time data updates in web and mobile applications.

1

Create the event data dictionary

Create a dictionary called event_data with these exact entries: 'event': 'order_placed' and 'order_id': 12345

Rest API

# Create the event_data dictionary
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with the keys and values exactly as shown.

2

Set the webhook URL

Create a variable called webhook_url and set it to the string 'https://example.com/webhook'

Rest API

event_data = {'event': 'order_placed', 'order_id': 12345}
# Create the webhook_url variable
# Your code here

Need a hint?

Assign the URL string to the variable webhook_url.

3

Write the function to send webhook notification

Write a function called send_webhook_notification that takes two parameters: url and data. Inside the function, write a print statement that shows: Sending webhook to {url} with data {data} using an f-string.

Rest API

event_data = {'event': 'order_placed', 'order_id': 12345}
webhook_url = 'https://example.com/webhook'
# Define the send_webhook_notification function
# Your code here

Need a hint?

Use def to create the function and an f-string inside print to show the message.

4

Call the function and print the notification

Call the function send_webhook_notification with the variables webhook_url and event_data to print the notification message.

Rest API

event_data = {'event': 'order_placed', 'order_id': 12345}
webhook_url = 'https://example.com/webhook'

def send_webhook_notification(url, data):
    print(f"Sending webhook to {url} with data {data}")
# Call the function to send the webhook notification
# Your code here

Need a hint?

Call the function with the two variables exactly as named.
