REST calls have different timeout values depending on operation. Which of the following is correct?

• A. 60 seconds for non-tracking, 180 seconds for tracking
• B. 120 seconds for non-tracking, 300 seconds for tracking/data retrieve
• C. 300 seconds for non-tracking, 120 seconds for tracking
• D. 120 seconds for both non-tracking and tracking

Answer: (B)

REST call timeouts reflect how long an operation is expected to take based on its complexity. Quick, non-tracking requests are treated as lightweight and are given a shorter timeout, while heavier operations such as tracking data retrieval can involve scanning large datasets and assembling results, so they’re allowed more time. Therefore, the standard mapping is a 2-minute timeout for non-tracking REST calls and a 5-minute timeout for tracking or data retrieval operations. If you’re dealing with large results, consider paging or asynchronous retrieval to avoid hitting the timeout.
