Get a call room token

When you already know roomID but need fresh credentials for joining the room, call signalingGetTokenByRoomID():

const { data: roomCredentials } =
  await openimsdk.signalingGetTokenByRoomID(roomID);

await mediaEngine.join({
  roomID: roomCredentials.roomID,
  token: roomCredentials.token,
  liveURL: roomCredentials.liveURL,
});

When the Promise resolves, data is RtcInviteResults. For field descriptions, see Start a one-to-one call. Connect to the media engine only after obtaining a valid token and roomID.

A room token is a short-lived sensitive credential. Use it only in memory; do not write it to logs, URLs, analytics events, or persistent storage.
