Why do I get an “Unexpected signature” error?

A signature is a string generated using the HMAC-SHA cryptographic hashing algorithm. It contains different values depending on the session type such as application ID, auth key, timestamp, etc.
Please make sure that you generate a signature correctly according to our documentation:

For example, you may use a third-party HMAC-SHA generator to generate a signature:

Additionally, please double-check our documentation related to session creation:

Also, the error appears if a combination of login, email, and password is used during login via the SDKs. Please use the login and password or the email and password combination.

Feel free to check our official documentation for more information that will help you to integrate QuickBlox services into your applications / projects or contact our Support team by submitting a ticket if you have any other questions.
