Answer 1

When someone connects with an app using QuickBlox, the app has to obtain an access token which provides temporary, secure access to QuickBlox APIs.

A session token is an opaque string that identifies a user and an app.

Session tokens are obtained via Create Session request.

Then, because of privacy checks, all REST API requests must be authenticated with a token - the QB-Token header of each request to REST API must contain valid session token.

Expiration time for session token is 2 hours after last request to REST API. Be aware about it. If you will perform query with expired token - you will receive error 'Required session does not exist'. In this case you have to recreate a session token.

Each REST API response contains header 'QB-Token-ExpirationDate' which contains session token expiration date.
