Rest API: Recordings


Twilio Video’s Group Rooms and Recording APIs enable you to record the audio and video shared in a Programmable Video Room. To turn on Recording in a Group Room, set the RecordParticipantsOnConnect property to true when creating the Room. Check the Rooms REST API documentation for additional information.

All Recording resources are located beneath the following Base URL.

Legal implications of call recording

If you choose to record voice or video calls, you need to comply with certain laws and regulations, including those regarding obtaining consent to record (such as California’s Invasion of Privacy Act and similar laws in other jurisdictions). Additional information on the legal implications of call recording can be found here.

Notice: Twilio recommends that you consult with your legal counsel to make sure that you are complying with all applicable laws in connection with communications you record or store using Twilio.

Returns a single Recording Instance resource identified by a RecordingSid.

Example: Retrieve a Recording

Loading Code Sample...

      HTTP GET to the /Media subresource

      Retrieves the media file associated to a given Recording Instance resource identified by a RecordingSid

      When you make a request to this URL, Twilio will generate a temporary URL for accessing this binary data, and issue an HTTP 302 redirect response to your request. The Recording will be returned in the format as described in the metadata, with the Content-Type header set according to the codec used to record the media

      Codec Content-Type value
      VP8 video/webm
      OPUS audio/webm
      PCMU audio/x-matroska
      H264 video/x-matroska

      The URL returned will only be available for 60 minutes, but a different expiration can be specified via the Ttl request param. If the composition is not yet available, a 404 is returned. If the recording is not available (for example, if its status is processing or deleted), an HTTP 404 response is returned.

      The HTTP GET request accepts the following parameters

      Name Description
      ContentDisposition Optional. Sets the Content-Disposition header of the redirect_to URL. Possible values are attachment or inline. Default value{a|v} (not PII)
      Ttl Optional. Duration in seconds for which the redirect_to URL can be used to retrieve the media file. The maximum expiration time is 7 days (604800) (not PII)

      The Content-Disposition header can be set in this request. By default, the value of this header is{a|v}.

      NOTE: You can play these recordings in media players that support the Matroska file format, like the VLC player. You can also use other programs like Chrome, ffplay or ffplayer to play these recordings.

      Example: Retrieve a Recording's Media

      Loading Code Sample...

          HTTP POST

          Not supported.

          HTTP DELETE

          Deletes the recording media file.

          The metadata for the Recording is preserved for a period of 30 days, and its Status is set to deleted. After this period, the metadata will not be available. By default, Recordings with deleted status are not returned when retrieving the Recordings list. To retrieve deleted Recordings, use the Status=deleted filter.

          Note that the 30 day period starts after the Status is set to deleted. After this period expires, the metadata will not be available.
