Problem using PayPalCheckoutSDK

Posted on

I got the client side portion working on my website, and now I'm trying to implement the server side portion as described on this page in section 6 Verify the Transaction:

https://developer.paypal.com/docs/checkout/integrate/

 

The server side is an ASP.NET MVC application using .NET 4.6.1.  Using NuGet, I've installed the PayPalCheckSdk library.  But, I'm not getting the references that the documentation is showing, PayPalCheckoutSdk.Core and PayPalCheckSdk.Orders.  Is there some other library I need to install?

 

Also, when I attempt to install the BraintreeHttp library from NuGet, I'm getting "BraintreeHttp-DotNet could not be installed because it is not compatible with any project in the solution".  Any suggestions?  Does anyone know what version of .NET the library requires?

Thanks in advance,

 

Richard

Hello,

Thank you for posting to the PayPal Merchant Technical Support Community.

Since you are not using the Braintree library and 100% using the PayPal sdk, we will look into reasons for getting SDK errors. I know that all our SDKs require a minimum of .net 4.5 framework. Using .net 4.6 framework is ideal because of the TLS 1.2 industry requirements.

 

Thank you,

Jennifer,

 

Thanks for the reply, but I'm confused by your answer.  The sample code provided on the Smart Button page, https://developer.paypal.com/docs/checkout/integrate/ , Step 6 - Verify the transaction, server-side, shows that both the BraintreeHTTP and PaypalCheckoutSDK libraries are being imported.

 

using System;
using System.Collections.Generic;
using System.Threading.Tasks;

//1. Import the PayPal SDK client that was created in `Set up Server-Side SDK`.
using BraintreeHttp;
using PayPalCheckoutSdk.Core;
using PayPalCheckoutSdk.Orders;

namespace Samples
{
  public class GetOrderSample

.....

 All that I'm trying to do at this point is just verifying the transaction that was generated by the customer using the PayPal page that the PayPal button invokes.  The link you provide doesn't seem to be for doing that.

Hi Richard,

Thank you for giving additional clarification on this issue. We will work on getting the documentation updated.

Here is the updated SDK from Git Hub: https://github.com/paypal/Checkout-NET-SDK

Braintree HTTP should not be used, it should be PayPalHttp, which is the reason you were getting the error message.
