_{Full disclosure: I work at Braintree.}

The warning you are getting suggests that the client token you generated may be incorrect. Test your integration with the sample valid client token given here. If that works, please check to make sure your API keys for the Braintree gateway you are using (sandbox or production) are set up correctly in your project. You can find your API keys from the Braintree control panel by selecting Account > My User > View API Keys. Do not post your API keys on Stack Overflow. If you still have trouble with your integration or have any more questions, please contact Braintree support.
