### Answer I don't have information in the available sources about recent changes to webhook responses. The documentation describes the current webhook functionality, including event types, payload structure, and timeout settings, but doesn't include a changelog or recent updates section [(1) ]() . The webhook specification indicates that webhooks POST payloads to your endpoint with a 10-second timeout, retry up to 3 times on failure, and include an

header for verification . The default webhook events are

,

call_ended

, and

call_analyzed

[(1) ]() [(2) ]() [(3) ]() . There are some community reports from 2024 about webhook issues, including a fix that was patched for cases where

webhooks weren't being sent for disconnection reasons like

,

dial_no_answer

, and

machine_detected

[(4) ]() . For the most current information about webhook changes, I recommend: - [Documentation]() - [Hire certified Retell partner]() Would you like a general answer based on my knowledge instead?
