The PayPal Sandbox is a self-contained environment within which you can prototype and test PayPal features and APIs. The PayPal Sandbox is an almost identical copy of the live PayPal website.

Link Paypal Developer

Create, edit and manage multiple PayPal apps. In each app, select the specific PayPal capabilities you want to offer to your customers. Every app gets a unique set of live and test API credentials. Log In with a PayPal account to get started.

Existing Log In with PayPal (formerly PayPal Access) apps are now brought over from devportal.x.com. Log in to manage your apps.
