Legacy v1: 2025-02-01

This page applies only to the legacy 2025-02-01 API. Use /v1 paths and Parcel-Version: 2025-02-01. The current API is described in Version migration.

POST /v1/shipments sends mass_grams as a top-level integer; it does not use package.weight_g. GET /v1/shipments returns data and has_more. Pagination uses offset and limit, with a default limit of 25 and maximum of 75. Advance offset by the number of records received while has_more is true.

The v2 cursor, its 11-minute expiry and the v2 next_cursor field do not exist in v1. Authentication still needs the bearer token and workspace header. This documentation does not state a v1 sunset date or promise that v1 has the v2 retry contract. Avoid projecting current-version behavior onto undocumented legacy behavior.
