Create a Webhook Endpoint

Create a simple webhook endpoint that receives notifications from an external service.

Framework: [Express, Flask, Django, FastAPI, etc.]
Service: [Stripe, GitHub, Shopify, or describe what's sending webhooks]

Keep it simple:
1. Create a POST endpoint at /webhooks/[service-name]
2. Parse the incoming JSON payload
3. Log what was received (for testing)
4. Return a 200 OK response quickly

I want to understand the basic pattern first. Show me:
- The endpoint code itself (keep it short!)
- How to read the event type (e.g., "payment.succeeded")
- How to access the event data (e.g., customer email, amount)
- What response to send back

I'm learning, so explain each part simply.
