The OpenTok Platform

A suite of advanced capabilities that power real-time

communication for your websites and apps.

Record, archive, and access every OpenTok session.

OpenTok’s Archiving API makes it easy to record your OpenTok sessions. Archives are easily evaluated through the OpenTok Dashboard, which displays size, status, date, and other essential information.

Rich with features

The Archiving API include a number of convenient features such as start-and-stop capabilities, server-side recording, and a simple, informative UI. Archives are pushed directly to your Amazon S3 account, with the OpenTok Cloud serving as a 72-hour backup.

High quality

Session recordings are output as MP4 with H.264 video and AAC audio to ensure crisp, high-quality playback. Our API automatically live-stitches video streams together for easy access with no post-processing required.

Cross-device compatibility & security

Archiving is compatible with all OpenTok-supported web clients and mobile endpoints. Whether you’re recording on a PC, MacBook, iPhone, or Samsung tablet, your conversations will remain secure.

Industry leading

We're constantly striving to push the scope and power of the OpenTok Platform to deliver the capabilities you need in the real world. OpenTok is the first and only company in the WebRTC space to offer archiving capabilities.

"We’ve had a lot of demand from our students for the ability to review their past tutoring sessions, and even share those conversations with their friends. OpenTok’s super simple Archiving API makes that possible. It seamlessly integrates into our existing OpenTok-powered application, and is helping us deliver the experience our customers really want, and need. We can’t wait to launch it."
— Kevin Law, Co-Founder, Cambly Inc.
