By default Dolphin has Payment module with PayPal integration in it. This module is used to add shopping cart functionality to Dolphin and process payments. For example, default Dolphin's Store module is integrated with Payment module. So, if you want to use Store to sell something on your site you need to start from setting up Payment module.

1. You need to install Payment module via Dolphin administration panel -> Tools -> Modules.
2. Now you are ready to set it up in Dolphin administration panel -> Modules -> Payment and first of all you need to fill in your PayPal requisites in 'Payment Details' block. Take a look at the form parts:
   • Mode. You may use PayPal in 2 modes (live and test). If you want to test payment on your site before going live you need to select 'test' mode and enter your sandbox email address in the last field of the form (Sandbox). If you ready to go live select 'live' mode. In this mode sandbox email is not needed.
   • Business. You need to specify your PayPal email address here.
   • Process type. You may use three types. They are direct, PDT and IPN. The easiest way is to use direct mode. In this mode you don't need to do any changes in your PayPal account. The second one is PDT. If you want to use it, you need enable PDT in your PayPal account and get a token there. Then you need to put it in the 'Identity token' field. This method is more secure then the 'Direct' one. The last one is 'IPN' mode. In this mode you need to configure your PayPal account too. Use URL like the following ​http://www.your_domain.com/path_to_dolphin/m/payment/act_finalize_checkout as notification URL in your PayPal. In this mode PayPal will notify Dolphin script about processed payment automatically when the payment was completed. It's useful when you have a lot of payments with eCheck or pending payments which are not processed immediately.
   • Connection type. You may use SSL or HTML. If your server supports SSL then it would be better for you to use SSL connection, because it's more secure.
3. Check 'Active' checkbox and save the form. Now you should be able to sell products in the Store.

There is an example of the easiest configuration.
Active: checked
Mode: live
Business: your PayPal email
Process type: direct
Connection type: HTML
Identity token: leave empty
Sandbox: leave empty
