Which of the following is a limitation of using client-side APIs?

The correct answer is that if the onsite JavaScript doesn’t fire, event data will not be logged. Client-side APIs rely on JavaScript executing in the user's browser to send data. If there's a JavaScript error, a user's ad blocker, or a slow network preventing the script from loading, the event data will not be captured. While compromising a private API key is a significant security concern, it's generally mitigated by using public API keys for client-side operations that only allow data submission, not retrieval of sensitive information. Client-side APIs typically have rate limits, but these are often designed to handle high volumes of individual user interactions and aren't necessarily "much lower" than server-side limits in a way that makes them inherently limiting for their intended purpose.
