If you are using the PayPal REST API via the PHP SDK you should look at the documentation at https://developer.paypal.com/webapps/developer/docs/api/

Specifically for auth the REST API uses OAuth 2.0 - https://developer.paypal.com/webapps/developer/docs/api/#authentication--headers

Here is a tutorial for using curl with the REST API: https://developer.paypal.com/webapps/developer/docs/integration/direct/make-your-first-call/
