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

Australia Post Shipping & Tracking API (REST, Australia)

Active

Australia Post's REST surface for domestic and international shipments originating in Australia. API key plus account-number authentication, separate from MyPost Business consumer flows.

DHL

DHL eCommerce Solutions Americas API (REST)

Active

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.

DHL Express MyDHL API (REST, global)

Active

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 API Farm (REST, Sweden)

Active

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 Post & Parcel Germany API (REST, Germany)

Active

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

FedEx REST APIs (Express, US, OAuth 2.0)

Active

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 Web Services (SOAP, legacy)

Legacy

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

La Poste Colissimo Web Service (SOAP, France)

Active

La Poste's SOAP and WSDL surface for Colissimo parcel shipments originating in France. Account number and password embedded in the SOAP envelope, French-language documentation primary.

Royal Mail

UPS

UPS Developer APIs (REST + OAuth 2.0)

Active

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 Legacy XML/SOAP Web Services (sunset)

Sunset

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

USPS APIs (REST, OAuth 2.0)

Active

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 Web Tools (XML, deprecated)

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.
