Hi @webinars4 ,

Have you tried searching [jwt.io](http://jwt.io) or stackoverflow for a library in PHP? Perhaps you will find the following helpful for programmatically generating a token in PHP:  
[GitHub - lcobucci/jwt: A simple library to work with JSON Web Token and JSON Web Signature](https://github.com/lcobucci/jwt)

Thanks,  
Will
