PayPal WSDL/XSD Schema Definitions
The PayPal Web Services schema and its underlying eBay Business Language (eBL) base and
core components are required for developing applications with the PayPal Web Services API.
The following are the locations of the WSDL and XSD files.

PayPal SOAP API Definitions
The PayPal SOAP API comprises individual API definitions for specific business functions.
As a foundation, the API relies on eBay Business Language (eBL) base and core components.
The core eBL structures AbstractRequestType and AbstractResponseType are the
basis of the SOAP request and response of each PayPal API. AbstractResponseType is
also the framework for error messages common across all PayPal APIs.
PayPal has made some schema design decisions that can affect how businesses design their
own applications.
Enumerations: Enumerations are defined directly in the PayPal API schema.
Troubleshooting information: The PayPal API returns information about elements that
trigger errors.
Backward compatibility: The PayPal API is versioned so that business applications are
backward compatible when new elements are introduced to the server-side schema.
NOTE: eBL defines many structures that are specific to processing auctions. PayPal’s SOAP
schema includes these definitions to maintain compatibility with eBay’s SOAP and
for possible future joint use of SOAP across both eBay and PayPal. The material
focuses only on those SOAP definitions pertinent to use of the PayPal SOAP API.
