Deprecation Notice:
This SDK is deprecated. You can continue to use it, but no new features or support requests will be accepted. For alternatives, please visit the current SDK homepage on the PayPal Developer Portal
PayPal .NET SDK
The PayPal .NET SDK makes it easy to add PayPal support to your .NET web application and is built on PayPal's REST APIs.
TLSv1.2 Update
The Payment Card Industry (PCI) Council has mandated that early versions of TLS be retired from service. All organizations that handle credit card information are required to comply with this standard. As part of this obligation, PayPal is updating its services to require TLS 1.2 for all HTTPS connections. At this time, PayPal will also require HTTP/1.1 for all connections. Click here for more information
Connections to the sandbox environment use only TLS 1.2.
PayPal Checkout v2
Please note that if you are integrating with PayPal Checkout, this SDK and corresponding API v1/payments are in the process of being deprecated.
We recommend that you integrate with API v2/checkout/orders and v2/payments. Please refer to the Checkout .NET SDK to continue with the integration.
2.0 Release Candidate!
We're releasing a brand new version of our SDK! 2.0 is currently at release candidate status, and represents a full refactor, with the goal of making all of our APIs extremely easy to use. 2.0 includes all of the existing APIs (except payouts), and includes the new Orders API (Disputes and Marketplace coming soon). Check out the FAQ and migration guide, and let us know if you have any suggestions or issues!
