Changelog

September 2026

September 6

• Imported product payloads preserve data.variants[].name when provided by the source, including SKUs without options. The field is optional.
• GET /v1/catalog/products and GET /v1/catalog/products/count accept repeated sourceIds parameters to filter by import sources. A product linked to several selected sources is counted once. Request an exact total with exact=true.

September 5

• Channel requirements include provenance and values by SKU. Consumers of bulk requirements must use variantValues for variant attributes.
• Channels adds publication execution and attempt history, plus verified linking of an existing external publication when a send requires review.

September 4

• Inventory CSV and XLSX exports generated by POST /v1/inventory/exports with template: false no longer include the status column. Update readers that expected this column; variant_status continues to represent the SKU status.

August 2026

August 25

• Storefront adds GraphQL through POST /graphql for nine selected reads. It requires x-Store-Domain; writes remain in REST.
• Storefront REST adds operations for retrieving payment methods and pickup options.
• Auth adds OAuth dynamic client registration, two-factor authentication, and account deletion.
• UCP is now stable and supports Bearer or X-API-Key authentication; its operations document the required context and idempotency behavior.
• Webhooks adds the order.created event.
• Public IDs are opaque strings; clients must not interpret or generate them.

July 2026

• New self-service portal for the Admin, Storefront, and Auth APIs.
• Canonical Markdown per page, llms.txt, and downloadable OpenAPI contracts.
• Lifecycle and visibility represented as explicit operation metadata.
• Navigation organized by API, context, and resource.

This log starts in July 2026 and does not reconstruct earlier changes. An operation's lifecycle label describes its current state; it does not establish a support or removal timeline by itself.
