Help manual of google checkout and paypal.

Question

I'm trying to find help manuals of Google Checkout and PayPal with screenshots, online.

Answer 1

The Paypal Developer Network contains documentation.

Google checkout really depends on how you want to integrate.

I don't know that either is going to really have a "help manual" for the entire service. Both Paypal and Google Checkout have a variety of services they provide, and the documentation you need will really depend on what you're trying to accomplish.
