This guide covers the Portico Simple Object Access Protocol (SOAP) API. The base elements and data types used in the Portico schema come from the "http://www.w3.org/2001/XMLSchema" namespace. Additional Portico schema elements are defined in the "http://Hps.Exchange.PosGateway" namespace.

The full Portico schema (PosGateway.xsd) is provided in the Portico SDK.
