Current Web Service Description Languages (WSDLs)

WSDL (Web Services Description Language) is an XML-based language for describing Web services and how to access them. WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information.

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.

2.2 TEM Environment
The USPS Test Environment for Mailers (TEM) is the dedicated Mail.XML test environment that is required for all new customers, as well as users migrating to a different electronic documentation (eDoc), to test their desired Mail.XML version in. TEM simulates the Production environment, and completion of TEM testing is required for access to the Production environment.

INFORMED DELIVERY® INTERACTIVE CAMPAIGNS:
MAILER/SUBMITTER TERMS AND CONDITIONS OF USE AGREEMENT

This Terms of Use Agreement (this "Agreement") is a legal agreement between You and the United States Postal Service, an Independent Establishment of the Executive Branch of the United States Government ("USPS" or "Postal Service"). Informed Delivery interactive campaigns (used herein as “Campaigns”) are at this time a free enhancement available to Mailers to the Informed Delivery notifications USPS provides to participating consumers for no additional postage fees. “Mailer(s),” “You” and “Your”, as used herein, include the Mail Owner/Brand, and any Mail Service Provider and any Advertising Agency acting on behalf of a Mail Owner/Brand in connection with the creation and submission of Content for an Informed Delivery Campaign.

Mailers agreeing to these Terms and Conditions, and complying with other requirements and specifications as may be published by USPS in PostalOne!, the Mailer Campaign Portal, the Shipper Campaign Portal or in the Informed Delivery Interactive Campaign Guide available at https://www.usps.com/business/informed-delivery.htm, or elsewhere on that site, may submit supplemental content (“Content”) to accompany or in some cases replace the grayscale scanned image that would otherwise be generated by USPS mail imaging processes (or, in the case of flats, replace the “image not available” notification) and provided to participating consumers as Informed Delivery notifications.  Content also may be submitted for display as a Campaign for packages being sent and tracked within the Informed Delivery interface.  In addition, some end users of Informed Delivery may set reminders to review Your Campaign up to ten days following the first opportunity to view Your Content. 

“Content” as used herein includes Ride-along Images, Representative Images, interactive links (URLs), and a Brand Display Name as text, or any other content that you provide to USPS by any means whatsoever (including but not limited to email, upload through PostalOne!, the Mailer Campaign Portal, the Shipper Campaign Portal through an API or otherwise).

By submitting Content to USPS in connection with any Informed Delivery Campaign, You agree to the terms and conditions specified below and to faithfully comply with all other rules, regulations, technical specifications and requirements for Informed Delivery Campaigns. The Postal Service reserves the right at any time to change or amend the Agreement, i.e., these terms, conditions, and notices under which this feature is offered. You may review the most current terms and conditions of use at https://www.usps.com/business/informed-delivery.htm. If You do not agree to, or cannot comply with, the Agreement as amended, You must stop using the feature. You will be deemed to have accepted the Agreement as amended if You continue to use the feature for Campaigns. You acknowledge and agree that Your use of the feature, in each instance, is subject to any such changes and that Your use of the feature constitutes acceptance of such changed terms. You agree to review this Agreement from time to time to ensure compliance with these terms and conditions.

In addition, USPS is beta testing a new Informed Delivery feature in select markets that allows Mailers to provide digital offers and/or anonymized mail to customers You have not mailed to directly. For eligibility and requirements, see the Beta Test for USPS Informed Offers Powered by Informed Address below.

Eligibility

Informed Delivery Campaigns must be submitted to accompany a letter-size mailpiece, flat-size mailpiece, or package that meets all mailability requirements of the Domestic Mail Manual. USPS reserves the right to refuse an Informed Delivery Campaign from a Mailer competing with a Postal Service product, service, or feature, although grayscale images of such mailpieces will be provided to consumers as part of the ordinary Informed Delivery notifications.

Representative Images

Representative Images are full color images submitted by the Mailer that can be displayed in lieu of the grayscale scanned image of a letter-sized mailpiece or in lieu of the “image not available” notification that would accompany a flat-size mailpiece (e.g., catalogs, magazines) in the USPS Informed Delivery daily digest email notifications, dashboard, or app. Representative Images must comply with the following requirements: (1) the Representative Image must be: (a) a reproduction of the address side of the mailpiece without an address showing, or (b) the nonaddress (obverse) side of the mailpiece; and (2) for flat-sized mailpieces required to be or that are mailed under covers or wrappers, the Representative Image must be an image of the Mailer’s corporate logo. Representative Images must also comply with all technical requirements (e.g., format, file size, pixel width and height, etc.) and other specifications as disseminated by USPS.

Ride-along Images and Interactive Links

Ride-along Images are required for all Informed Delivery Campaigns. Ride-along Images are full color images that accompany either the Representative Image selected by the Mailer in accordance with the requirements above, or the grayscale image of the scanned mailpiece (or in the case of a package, the notification that the package will be arriving soon) in the USPS Informed Delivery email notifications or dashboard. Ride-along images must comply with the following requirements: (1) the Ride-along Image must directly relate to the promotion or offer contained in the mailpiece or what was shipped in the case of a package; (2) the Ride-along Image must be sized to the full space allowed or be reduced in size based on the ratio compared to the Representative Image; and (3) regardless of Mailer identity, the Ride-along Image language may not facilitate diversion from Postal Service products, services, or features (including “pay online” and similar CTAs). URLs and interactive links submitted as part of the Content with Ride-along Images must comply with the following requirements: (1) all URLs and links submitted as Content for an Informed Delivery Campaign must be submitted as HTTPS; (2) all URLs and links submitted as part of an Informed Delivery Campaign must lead directly to a landing page directly associated with the physical mailpiece or package utilized in the Campaign, or Your website’s homepage; (3) all URLs and links must be free of any malware, viruses, errors, or other aspects that could negatively impact the Informed Delivery feature and/or consumer experience with the feature; (4) You must monitor the Campaign and any threats, vulnerabilities, malware and malformed links must be addressed and reported to USPS within twenty-four (24) hours of discovery; and (5) any web site being linked to from an Informed Delivery campaign and/or USPS.com shall be branded in a manner or have a look and feel (“trade dress”) that will not emulate USPS.com or create a likelihood of confusion with USPS trade dress or otherwise lead consumers to believe or confuse consumers that they are on a USPS site. To comport with USPS policies related to exit pages, and with the goal of not having an exit page, You acknowledge, understand and agree that the standard for no exit page as set forth by Postal Service Management is that the site being linked to needs to be substantially different from USPS sites (i.e., the site’s appearance must be one that a person is unlikely to confuse with USPS sites or properties, or to think is a part of the USPS websites or properties, and possesses a distinct look and feel from those of USPS sites or properties, and the site must have a distinct URL separate and apart from the URLs of USPS.com and not use any USPS marks).
