I’m trying to pass url params via the /authorize endpoint. I found lots of helpful links and documentation that led me to this documentation for the Auth0 PHP SDK (https://auth0.com/docs/libraries/auth0-php/authentication-api) that would allow me to add params to the /authorize url (which I could then use to style a user who is signing up differently from a login on the Universal Login page).
I copied the code from the example (replacing the env variables as appropriate), but when I execute the code, I receive an error
Fatal error: Uncaught Error: Class ‘Auth0\SDK\Store\CookieStore’ not found
This seems to be something missing in my install of the SDK, which basically means a dead-end for me.
Any help or guidance would be much appreciated.
