### Answer To receive the transcript only at the end of the call, you should utilize the "End of Call Report" feature provided by Vapi. This feature sends a POST request to your server URL with a message containing the

type

as "end-of-call-report" once the call concludes. The message includes the call's

endedReason

, along with other details such as the

recordingUrl

,

summary

, and importantly, the

transcript

of the entire conversation [(1)]() . This setup ensures that instead of receiving updates throughout the call, you get a comprehensive transcript only after the call has ended. You can find more details on how to set up and handle server events in the Server Events documentation.
