I get this error when trying to run this.

PHP Fatal error: Uncaught Error: Class 'Discord\OAuth\Discord' not found in /var/www/html/index.php:5
Stack trace:

Did You install it correctly? (vendor folder existence)

Did You load the Composer autoloader?

include __DIR__.'/vendor/autoload.php'

[tallypokemap]

I cloned the git and ran composer. What about vendor folder existence?

[Hackmastr]

Does it exist...?
If yes check if there is a subfolder with the library inside

[tallypokemap]

It was the autoloader. I added require "vendor/autoload.php"; to the php code.
Thanks for the help.

Where can I find the class AbstractProvider? It seems to provide the getAuthorizationUrl() method.

Found it
