Webhooks allow an e-commerce platform to send real-time HTTP POST notifications to an external URL whenever a specific event (e.g., new order, shipment update) occurs.

Question 3

Which HTTP status code should a third-party API return to indicate that a request was successful and a new resource was created?

HTTP 201 Created is the correct status code to return when a POST request successfully creates a new resource such as a new order or customer record.

Question 4

What authentication mechanism do most e-commerce APIs (e.g., Shopify, Stripe) use to verify API consumers?

Accepted Answer

API keys or OAuth 2.0 tokens
