🧠 Key Concepts

Understand the core components of our SDK:

Meeting - A Meeting represents Real-time audio and video communication.

Note: Don't confuse the terms Room and Meeting; both mean the same thing 😃
Sessions - A particular duration you spend in a given meeting is referred as a session, you can have multiple sessions of a specific meetingId.
Participant - A participant refers to anyone attending the meeting session. The local participant represents yourself (You), while all other attendees are considered remote participants.
Stream - A stream refers to video or audio media content that is published by either the local participant or remote participants.

🔐 Token Generation

The token is used to create and validate a meeting using API and also initialize a meeting.

🛠️ Development Environment:

You may use a temporary token for development. To create a temporary token, go to VideoSDK's dashboard .

🌐 Production Environment:

You must set up an authentication server to authorize users for production. To set up an authentication server, please take a look at our official example repositories. videosdk-rtc-api-server-examples
