First, you need to go to Paypal, get an account and take a look at their developer pages. &nbsp;They have everything you need there. &nbsp;The problem is usually figuring out their complicated way of doing things. &nbsp;I think they make it difficult so it is difficult to crack.

I've figured it out with a help of Pay Pal support - Adaptive Payments and Preapprovals is the key to get wanted functionality.

Hello,<br />
<br />
I must implement pay pal functionality with WCF service. I was never working with pay pal. Functionality I must provide is paying through pay pal. Does someone know where to start with this, where to get basic information about pay pal in .NET programs? I guess they have some dll which I can use? Perhaps some manuals? If some of you had already working on this issue I would be really glad for any advice on how to start.<br />

Pay pal as WCF service

Windows Communication Foundation (WCF) is a tool used to implement and deploy a service-oriented architecture (SOA) to support distributed computing where services have remote consumers. It features a runtime and a set of APIs in the .NET Framework for building connected, service-oriented applications. Services typically have a WSDL interface (Web Services Description Language) that any WCF client can use to consume the service, regardless of which platform the service is hosted on. WCF implements many advanced Web services (WS) standards such as WS-Addressing, WS-ReliableMessaging, WS-Security, RSS Syndication Services, WS-Discovery, routing and better support for REST services.

Electronic commerce (e-commerce) is the trading in products or services using computer networks, such as the Internet. E-commerce draws on technologies such as mobile commerce, electronic funds transfer (EFT), supply chain management, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems. Use this topic to discuss online shopping carts, online marketplaces, and e-commerce platforms.

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
