how to integate paypal with https

[amit]

Hello everyone,

I have 3 main questions and they are:

1. Is it possible to integrate the PayPal payment gateway within our
website? My client doesn't want the customer to be directed to the
PayPal website to complete the transaction.

2. I tried integrating the 'Ruby PayPal Gem' from http://www.elctech.com/projects/paypal
but ran into some issues. I am using the PayPal SOAP API on Rails
1.2.5. I have a PayPal Pro and Developer Account but I did not get
sandbox_api.crt, sandbox_api.key, live_api.crt and live_api.key as
required for this installation.

My questions are a) Is this library compatible with Rails 1.2.5? and
b) Could someone direct me to a good tutorial of installing this gem?

3. Is there a way to work with Active Merchant on Rails 1.2.5 because
I think it is only compatible with the latest version?

I've been trying to crack this since the last 2 days and I am
desperate to get this going. Any help will be greatly appreciated.

Thanks!
Amit
