In order to access QuickBlox APIs you need to authenticate your application with QuickBlox server.
A token-based authentication should be used to provide secure access to QuickBlox APIs.
The token-based authentication works by ensuring that each request to the server contains a token that is verified by the server for the authenticity. When the authenticity is verified, the server responds to the request.
There are two types of tokens: application session token and user session token.
The application session token is limited to read-only permissions preventing changes to application data while the user session token is not restricted in permissions and allows for making edits to application data.
