This document contains a Reference Guide to the USPS Returns Label API. See the Developer’s Guide to learn the administrative process for gaining access to the Web Tools APIs as well as the basic mechanism for calling the APIs and processing the results. The Developer’s Guide also contains information on testing and troubleshooting.

Nota: The Request Parameter sections present the XML input tags for generating live requests along with the restrictions on the values allowed. An error message will be returned if an incorrect value is entered. Also, be aware of the maximum character amounts allowed for some tags - an error will return if values passed exceed these limits. Where a parsing expression or character limit is not documented for tags defined as a String, Web Tools will simply pass in the characters up to the maximum amount allowed and disregard the rest. This is important since the resulting value could prevent a correct response. We recommend integrators check the character length of all values passed in the API request to avoid any truncation or unsuccessful responses.

When building the XML request, pay particular attention to the order and case for tags. An error message will be returned if an incorrect value is entered. Remember that all data and attribute values in this document are for illustration purposes and are to be replaced by your actual values.

1.1 Before you get started:

For information on registering and getting started with Web Tools, please refer to the Step-By-Step guide found on the Web Tools Technical Documentation Page.

Nota: The Web Tools user ID (i.e.“123ABCD456”) you receive upon registration will not work at www.usps.com (also reference: https://es-reg.usps.com); USPS Web Tools API user ID credentials are separate and required for API use.

Additional onboarding is required before integrators can begin using the Web Tools USPSReturnsLabel API to generate USPS Returnsservice labels. Integrators should contact the USPS Mailing & Shipping Solutions Center (MSSC) at 1-877-672-0007 for assistance. Business hours for the MSSC are Monday-Friday from 7:00 AM-7:00 PM Central. The USPS Returns web page can also be referenced: https://es.usps.com/business/return-services.htm

2.0 USPS Returns Label API

2.1 Overview

The Web Tools USPS Returns Label API enables customers to receive USPS Returns service labels which are processed using the new automated returns process via Package Platform. USPS Returnsservice account holders will pay postage and fees through an Enterprise Payment System (EPS) account so that items can be returned by their customers (at no charge to their customers) using merchant provided USPS Returns service labels. The API allows integrators to request USPS Returnsservice labels for items that can be mailed using First-Class Package ReturnService, Priority Mail Return Service, and Ground Return Service. For additional USPS Returns service details, reference: https://www.federalregister.gov/documents/2020/02/25/2020-03170/usps-returns-service.

Initial onboarding will include:

Part I: Technical Integration Specialist (TIS)

· Package Platform enrollment

· USPS Returns enrollment

· EPS account enrollment for electronic funds transfer for payment of USPS Returns service postage.

· USPS Web Tools API registration resulting in generation of Web Tools user ID and access configuration

· Mailer ID (MID) enrollment

· Customer Registration ID (CRID) enrollment

· Configuration of Destination Delivery Address (where applicable)

Customer Types:

The USPS Returns Label API will support the following configuration options determined during initial customer onboarding:

· Non-manifesting (SSF) Option: Supports creation of returns label to a single delivery destination address configured per Web Tools UserID. Unique ZIP4 for returns supported. Nota: The ability to generate returns labels to multiple delivery destinations requires separate Web Tools UserIDs for each destination address.

· Manifesting (SSF) Option (not eFulFillment): Supports creation of returns label to a configured delivery destination address with options for Insurance extra services. Unique ZIP4 for returns supported. A Shipping Services File will be submitted by Web Tools for returns labels on behalf of the integrator.

· Manifesting (SSF) eFulfillement for Returns Option: Supports creation of returns label for eFulfillment returns customers to a delivery destination address collected in the API request with options for Insurance extra services. A Shipping Services File will be submitted by Web Tools for returns labels on behalf of the integrator. Nota: The USPSReturnsLabel API will AMS-validate the destination addresses provided by eFulFillment customers or an error will return. Unique ZIP4s are not applicable to these customers.

5.0 Appendix C – Unique ZIP+4

Web Tools USPSReturnsLabel allows a unique returns ZIP4 which can be used instead of the ZIP4 returned from AMS in the XML response <RetailerZip4>, barcode, label, receipt, and SSF.

Context: Today local AMS generates a unique returns destination ZIP4 for larger volume returns shippers, but doesn't share this data outside of AMS DB with other internal systems. As a result, unique returns ZIP4 will fail AMS validation and standardize to ZIP4 of the physical address. For the Web Tools USPS Returns API, a configured unique ZIP4 allows customers to bypass the AMS ZIP4.

Ex. Destination Address: “16840 BUCCANEER LN HOUSTON, TX 77058 + XX50* – the unique ZIP4 is “XX50”, AMS standardizes to “2563” – when the unique ZIP4 option is configured in Web Tools, the unique returns ZIP4 of "XX50" is used.
