Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • cancel

    Cancel a pending submission on Chrome Web Store. Can be used to cancel an item currently in review.

  • deploy-percentage

    Set the published deploy percentage for staged rollout on Chrome Web Store. The new percentage must be higher than the current target. Only available for items with 10,000+ seven-day active users.

  • get

    Fetch publication status through v2 (alias of status). Version 2 no longer returns listing metadata or supports projection; use get-metadata-ui for draft listing text.

  • get-metadata-ui

    Read the current draft listing description, category, homepage and support URL from the signed-in Developer Dashboard. This is not the published listing.

  • publish

    Publish an extension to Chrome Web Store. Supports immediate publish, staged publish, initial deploy percentage, and skip-review.

  • status

    Fetch the current status of an extension on Chrome Web Store. Returns published/submitted revision status, deploy percentage, version, takedown/warning flags, and last upload state.

  • update-metadata

    Save draft listing description, category, homepage or support URL via the signed-in Developer Dashboard, then reload to verify. Does not submit for review. Package title/summary, raw payloads, and icon uploads are unsupported.

  • update-metadata-ui

    Save draft listing description, category, homepage or support URL via the signed-in Developer Dashboard, then reload to verify. Does not submit for review. Package title/summary, raw payloads, and icon uploads are unsupported.

  • upload

    Upload a ZIP file to update an existing Chrome Web Store item draft. Note: Creating new items via API is not supported in v2 — use the Developer Dashboard to create new items.
