Short answer

D Uses the @app.post decorator to create an endpoint that receives Meraki webhook POST requests.

Key Takeaways

The key is distinguishing between code that sends a webhook and code that receives it; receiving requires an HTTP server endpoint configured to accept POST data.

This question tests your ability to identify the correct Python code for receiving Meraki webhooks. The solution involves using a web framework decorator to listen for POST requests.

Common mistake: Choosing an option that uses `requests.post()` or a GET method, which either sends data out or fails to capture the incoming webhook payload.

Expert Analysis

To receive a Meraki webhook, the Python application must expose an HTTP endpoint that accepts incoming POST requests from the Meraki dashboard. The standard and most efficient way to handle this in modern Python is using a web framework like FastAPI or Flask.

Option D correctly utilizes the @app.post decorator from FastAPI. This decorator registers a route that explicitly listens for HTTP POST methods. When Meraki sends a webhook notification (which is always a POST request containing JSON payload data), it hits this endpoint, and the function processes the incoming data. This matches the requirement of 'receiving' a request.

Option B likely represents a script that sends a request (using requests.post) rather than receiving one, which is a common trap. Option A and C may use incorrect HTTP methods (like GET) or lack the necessary routing decorators to serve as an API endpoint. Comments confirm that D is the correct choice because it sets up an API to receive the POST request, whereas other options might be sending requests or using wrong verbs.

Exam Strategy

When asked about 'receiving' webhooks or API calls, look for server-side code snippets that define routes or endpoints (e.g., @app.post, @app.route). Avoid options that simply make outgoing HTTP calls unless the question specifically asks about triggering an event. Always check the HTTP verb; webhooks are almost exclusively POST requests.

Frequently Asked Questions

Why is POST used for Meraki webhooks?

Webhooks are push notifications sent from a source (Meraki) to a destination. POST is used because it allows sending a payload of data (the alert details) in the request body.

What is the role of @app.post in FastAPI?

It is a decorator that maps a specific URL path to a function that handles incoming POST requests, making the function act as a webhook receiver.

  1. Xixmk 👍 4
    D is correct, Webhook on Meraki uses POST to send an alert to external server
  2. lente_kriebels 👍 2
    Never mind this is fastapi decorators. It is D setting up a API which receives POST
  3. Dominican_Beard 👍 1
    D is correct here. send POST request to the API endpoint
  4. lente_kriebels 👍 1
    Incorrect it is B. Mark the word receive
