Provider documentation

This page is for adapter maintainers. Public verification status is summarized on Evidence.

Shippo

Primary source: Shippo OpenAPI

Enum values are often composed through separate schemas. Read the full composed schema rather than only the base field.

ShipStation v2 / ShipEngine

Primary sources:

• ShipStation API documentation
• ShipEngine OpenAPI repository

The repository schema can lag the hosted documentation. Check both before changing an enum, customs field or purchase request.

ShipStation v1

Primary sources:

• Customs Item
• International Options
• Create Label
• Get Rates

Endpoint pages link to separate model pages. Field-level claims must be checked against the model page, not the endpoint summary.

Easyship

Primary source: Easyship documentation index

Reference pages include inline schemas. Check the schema for field nesting, required values and defaults. Easyship documents omitted/null incoterms as DDU.

Verification rules

For an adapter change:

1. Confirm the field or behavior in a current provider-owned schema or model page.
2. Add a payload test proving the value reaches the outgoing request.
3. Add a parser test using a sanitized provider response when one is available.
4. Run a live read-only or sandbox call when credentials and provider safety allow.

An HTTP 200 response or a non-empty downloaded file does not prove the requested documentation was returned. Check page title, endpoint name and expected fields.
