Session Resource

A Session is a single instance of two individuals communicating. It belongs to a Service and maps two Participants for a Proxy application. Sessions allow you to:

Specify a unique identifier relevant to your use case, such as a job ID
See whether a given Session is closed or not and the reason it has been closed
Control the length of time the Session should be active

Delete a Session resource

DELETE https://proxy.twilio.com/v1/Services/{ServiceSid}/Sessions/{Sid}

Deleting a Session removes it permanently. Related Participants and Interactions will also be deleted.

(error)

Danger

Any Message or Call logs created during interactions for this Sitzung will be deleted automatically after 90 days of the Session being closed, as per our Session retention policy. If you want to delete these resources before then, you must issue DELETE requests for the inbound and outbound resources of all child Interactions directly. Once you have deleted a Session, those resource SIDs will not be discoverable via Proxy.
