Description

Push messages in a client/server application are defined as sending data to a client without the client requesting it. A defined trigger can cause a push message to be sent. A pull message occurs when the client sends a request and a subsequent response is delivered to the client. The Postal Service supports WSDLs for the following four systems: FAST, PostalOne, eDoc, Full-Service Data Feedback, and Profile Management.

There are five WSDLs categories: CAT, TEM, Pre-Production, Production, and Push Subscription. The links for downloading WSDLs are defined by the environment, Mail.XML version and message type. Select the version of the WSDL based on the environment and Mail.XML version you will exchange the Mail.XML data.

2.1 CAT Environment
This section describes the Mail.XML WSDLs that are supported in the CAT Environment. These WSDLs are for the upcoming release and are accessible and available only for the selected mailers who participate in USPS CAT certification phase. These WSDLs are subject to be revised at any time without notice. It is recommended for the mailers not to use these WSDLs unless participating in the CAT phase.
