Webhook receivers in No-Code - Mini Project: Build & Apply

Webhook Receivers

📖 Scenario: You are building a simple system to receive notifications from an online service. This service sends data automatically to your system whenever an event happens, like a new user signing up or a payment being made. Your system needs to be ready to accept these messages and process them.

🎯 Goal: Create a basic webhook receiver setup that can accept incoming data, check for a specific event type, and store the event details for later use.

📋 What You'll Learn

Create a data structure to hold incoming webhook events

Add a configuration variable to specify the event type to listen for

Write logic to filter and store only the events matching the specified type

Complete the setup by adding a confirmation step to acknowledge receipt

💡 Why This Matters

🌍 Real World

Webhook receivers are used in many online services to get real-time updates, like payment notifications, user signups, or system alerts.

💼 Career

Understanding webhook receivers is important for roles in web development, system integration, and automation where services need to communicate instantly and reliably.

1

Create the initial data structure for webhook events

Create a list called incoming_events with these three dictionaries exactly: {'event': 'user_signup', 'data': 'User A'}, {'event': 'payment_made', 'data': 'Order 123'}, and {'event': 'user_signup', 'data': 'User B'}.

No-Code

# Create a list called incoming_events with three event dictionaries
# Your code here

Need a hint?

Think of incoming_events as a list that holds all the messages your system receives.

2

Add a configuration variable for event type

Create a variable called event_type_to_listen and set it to the string 'user_signup'.

No-Code

incoming_events = [
    {'event': 'user_signup', 'data': 'User A'},
    {'event': 'payment_made', 'data': 'Order 123'},
    {'event': 'user_signup', 'data': 'User B'}
]
# Create a variable event_type_to_listen set to 'user_signup'
# Your code here

Need a hint?

This variable tells your system which event messages to pay attention to.

3

Filter and store matching events

Create an empty list called filtered_events. Then use a for loop with variables event to go through incoming_events. Inside the loop, use an if statement to check if event['event'] equals event_type_to_listen. If yes, add event to filtered_events.

No-Code

incoming_events = [
    {'event': 'user_signup', 'data': 'User A'},
    {'event': 'payment_made', 'data': 'Order 123'},
    {'event': 'user_signup', 'data': 'User B'}
]
event_type_to_listen = 'user_signup'
# Create filtered_events list and add matching events from incoming_events
# Your code here

Need a hint?

This step picks only the events you want to handle and saves them separately.

4

Add confirmation of receipt

Create a variable called confirmation_message and set it to the string 'Webhook received and processed'.

No-Code

incoming_events = [
    {'event': 'user_signup', 'data': 'User A'},
    {'event': 'payment_made', 'data': 'Order 123'},
    {'event': 'user_signup', 'data': 'User B'}
]
event_type_to_listen = 'user_signup'
filtered_events = []
for event in incoming_events:
    if event['event'] == event_type_to_listen:
        filtered_events.append(event)
# Create confirmation_message variable with text 'Webhook received and processed'
# Your code here

Need a hint?

This message confirms your system has successfully handled the webhook events.
