Questions about PayFlow Pro API and where download latest release? (paypal_base.dll, Version 5.6.65.1, Runtime v1.1.4322)

Question

I'm constantly confused with PayPal (x.com vs. developer.paypal.com, API names, etc.) and need help locating the latest API that I'm currently using in my project. I have a Visual Studio 2010 C# reference to this DLL:

paypal_base (Properties: version 5.6.65.1, Runtime Version: v1.1.4322)

Questions:

Q1. What is URL of latest download?

Q2. I downloaded payflow_dotnet_setup_v4.33.zip and I'm reading "PayPal Payflow SDK for .NET Developer's Guide), BUT there is NO MENTION of any of the current calls I'm already using that look like this. Why?

        DoCaptureRequestType pp_request = new DoCaptureRequestType();
        pp_request.AuthorizationID = authorizationId;
        return (DoCaptureResponseType)caller.Call("DoCapture", pp_request);

Q3. Is this API deprecated in liu of REST API?

I'm SO confused.

Answer 1

X.com was the home of the developer site for PayPal, but it is being migrated over to developer.paypal.com. Eventually everything you need for Payflow, PayPal, and etc to get started processing payments will be found on developer.paypal.com. You can find the most recent version of the PayPal SDK's here. The REST API's are newer API's which can be used as well, however they are still new and they are not supported for every country yet and not all of the features are available yet.
