Why do I get an “Unauthorized” 401 error?

The "Unauthorized" error means that you have not created the user for your application in the Dashboard OR your login/email or password are wrong, or if the user exists - the session was created without user credentials.

Or 401 error can occur if the application/user session token has expired and you need to generate a new one.

To access QuickBlox APIs you need to authenticate your application with the 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 authenticity. When authenticity is verified, the server responds to the request.

There are two types of tokens: application session tokens and user session tokens.

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 the user to make edits to application data.

Please make sure that you follow the steps described in our documentation:
