Payflow SDK

The Payflow Software Development Kit (SDK) is a set of APIs to allow you to integrate the

Gateway with your application or website. This section includes:

 “Preparing the Payflow Gateway Client Application” on page 51.

 “Activating Your Payflow Gateway Account” on page 52.

 “Host URL Addresses” on page 52

NOTE: Each SDK includes full API documentation.

IMPORTANT: The Payflow SDK is available as a .NET or Java library. Using these SDKs is

recommended to simplify integration. Alternately you can build your own

API by posting transactions directly to the Gateway servers using HTTPS.

See

“Posting Transactions Directly Without the Payflow SDK” on page 156

for more information.

Any reference to Payflow SDK or the API in this documentation is referred to simply as the

Payflow SDK.

Preparing the Payflow Gateway Client Application

Unless you are building your own API and using HTTPS to post to the servers, you need to

obtain the Payflow SDK. Follow these steps.

1. Download the Payflow SDK.

From the SDKs Downloads page, download the Payflow SDK appropriate for your platform.

2. Extract the files to a local directory.

3. Configure your firewall.

If you have a stateful firewall, enable outbound traffic for SSL (port 443). The firewall

keeps state on the connection, and automatically permits the inbound response from

PayPal.

If you do not have a stateful firewall, enable inbound and outbound traffic for SSL (port

443). Outbound traffic permits the initial Gateway request, while inbound permits the

response from PayPal.

4. Read the Readme.txt file.

The Readme.txt file includes integration information and samples that illustrate how to use

the client application in your development environment.
