Documented steps
Single staged update: PATCH https://api.webflow.com/v2/collections/{collection_id}/items/{item_id} (scope cms:write). Body accepts fieldData, isArchived, isDraft and cmsLocaleId, all optional.
Bulk staged update: PATCH https://api.webflow.com/v2/collections/{collection_id}/items with an items[] array of { id, cmsLocaleId?, fieldData }, up to 100 items per request.
A live-update variant exists at PATCH /v2/collections/{collection_id}/items/{item_id}/live for pushing a change straight to the published site.
Archived and draft are not endpoints — they are the isArchived and isDraft booleans set through these same update calls.
Both update endpoints accept a skipInvalidFiles query parameter, which defaults to true.
Publish afterwards (item publish or site publish) unless you used the /live variant.
Known gotchas
Webflow does not document whether fieldData is merged or replaced on PATCH. Send the complete desired fieldData object rather than assuming a partial merge — assuming merge risks silently blanking fields you omitted.
Bulk update touches the primary locale only unless you include cmsLocaleId per item. On a localized site this quietly leaves every secondary locale stale.
skipInvalidFiles defaults to true, so a broken image or file URL is dropped silently instead of erroring — verify the response rather than trusting a 2xx.
Archiving keeps the record and flags it out of published output; it is not a delete and the slug stays taken, so a later create with the same slug still collides.
