Explanation

Webhooks are the technique Susan is using because they are user-defined HTTP callbacks triggered by specific events, allowing a server to automatically "push" real-time data to other applications the moment something happens - rather than requiring those applications to repeatedly poll for updates.

Why the distractors are wrong:

• Web shells (A) are malicious scripts used by attackers to gain unauthorized remote access to a server - they are a cybersecurity threat, not a legitimate API communication method.
• REST API (C) is a widely-used architectural style for APIs, but it operates on a pull model where the client must make requests to retrieve data - it does not automatically push updates on trigger events.
• SOAP API (D) is a protocol-based API standard that also relies on client-initiated requests and uses XML messaging - it does not natively support event-driven push notifications.

Memory Tip: Think of Webhooks as a doorbell - instead of you constantly checking if someone is at the door (polling), the doorbell alerts you the moment someone arrives (event-triggered push). The key phrase to recognize in exam questions is "user-defined HTTP callback," "trigger events," or "real-time push" - these all point directly to Webhooks.
