implement old php class

[afik-gilboa]

I have an old PHP class for paypal, but the credentials in the file don't match what I get from the paypal console.

its a very old file and I haven't had need to change it for a few years, so maybe things are different now.

please help.

(I didn't know which tags to apply)

the file looks like this:

/**
    * API Credentials
    * Use the correct credentials for the environment in use (Live / Sandbox)
    * @Var array
    */
   protected $_credentials = array(
      'USER' => 'username.my_domain.co.il',
      'PWD' => 'PASSWORD',
      'SIGNATURE' => 'ABCD1234ABCD1234ABCD1234ABCD1234ABCD1234',
   );

and that is what I get from paypal console:
