   An organization's webhook receiver occasionally returns HTTP 500 errors due to temporary database issues. The webhook provider retries failed deliveries up to three times with exponential backoff. However, the receiver processes the same event multiple times when a retry succeeds after the original request was actually processed but the response was lost. What should the receiver implement to avoid duplicate processing?

   • AUse the event ID from the payload to check if the event has already been processed before acting on it.
   • BIgnore all retries and only process the first delivery attempt.
   • CReturn HTTP 200 immediately before processing the payload to prevent retries.
   • DIncrease the retry count to five to reduce the chance of duplicate processing.
