Carrier API Surfaces
Carrier APIs grouped by vendor, business unit, country, and protocol. Each page documents one specific surface so DHL Express, DHL eCommerce, and DHL Parcel DE are not collapsed into a single "DHL" summary.
Australia Post
DHL
REST surface for DHL's domestic and international parcel network in the Americas. Uses a token-based auth flow that is unrelated to MyDHL API and a separate developer portal.
Modern REST surface for DHL's international express network. OAuth-style basic-credential header, separate sandbox account, and a JSON contract that is unrelated to DHL eCommerce or DHL Parcel DE.
DHL Freight's Sweden-specific REST hub for booking, pricing, validation, and shipping documents on Sweden domestic and Sweden-originating international road freight. Wholly separate portal, base URLs, and credentials from MyDHL Express, DHL eCommerce Americas, and DHL Parcel DE.
DHL's domestic Germany parcel and post API surface. REST-based, German-language documentation primary, separate credentialing through DHL Geschäftskundenportal. Distinct from MyDHL Express.
FedEx
Modern REST surface for FedEx Express in the US, exposed through developer.fedex.com. OAuth 2.0 client_credentials, JSON payloads, sibling to the legacy FedEx Web Services SOAP product.
FedEx's legacy SOAP/WSDL surface for Ship, Rate, and Track operations. Still in production at this page's last review but explicitly the older surface; new integrations should target the FedEx REST APIs.
La Poste
Royal Mail
UPS
UPS's modern REST and OAuth 2.0 surface, replacing the legacy XML/SOAP web services that were sunset on 2024-06-03. Covers Shipping, Rating, Tracking, Address Validation, and Time in Transit.
UPS's pre-2024 XML and SOAP web services. Sunset on 2024-06-03. Documented here so legacy integrators searching for 'UPS XML API' can land on the correct migration path rather than a 404.
USPS
The modern USPS REST surface at developer.usps.com. OAuth 2.0 client_credentials, JSON payloads, replacing the legacy USPS Web Tools XML services.
USPS's pre-OAuth XML-over-HTTP API. Documented here so integrators searching for USPS Web Tools land on the correct migration path to the modern REST USPS APIs.
