Single answerYou are automating a Cisco enterprise solution and need to configure WebHook Alert APIs to notify your team whenever a network device goes down. What is the primary action you must ensure to successfully receive and process these notifications?
- A
Register the WebHook URL with the API provider and validate the subscription handshake.
- B
Configure OAuth 2.0 authentication for all incoming WebHook requests.
- C
Set up a polling mechanism to frequently check the WebHook endpoint for updates.
- D
Create a custom WebHook API server with a static IP address to avoid connection issues.
Show answer and explanation
Correct answer: A
Explanation
WebHooks are used to deliver real-time event notifications from an API provider to a registered endpoint. To successfully receive these notifications, you must first register your WebHook URL with the provider and complete the handshake process to verify the subscription. This ensures that notifications are sent to a verified and correct endpoint. Other options, such as OAuth and polling, do not align with the WebHook mechanism.
- A. Correct.
This is the correct answer because WebHooks require you to register a callback URL with the API provider and complete a validation process (handshake) to ensure notifications are sent to the correct endpoint.
- B. Incorrect.
While authentication is important, OAuth 2.0 is not typically required for WebHook requests as they often rely on pre-shared secrets or tokens for security.
- C. Incorrect.
WebHooks are event-driven and do not require polling. Polling is a separate mechanism that is not applicable to WebHooks.
- D. Incorrect.
Although having a stable server is beneficial, a static IP is not a mandatory requirement for WebHook APIs as DNS-based URLs are commonly used.
