Set the variants
PUT /rest/v1/products/{id}/variants
Sends the product's COMPLETE variant set: entries are matched to existing variants by id, then by sku, and keep their ids. On a matched variant only the fields you send change; variants not in the set are removed; entries with no match are added. Same rules as creation: at most 3 option names and every option combination present (channels publish the full matrix). Removing variants of a product live on a channel asks the two-step confirmation. Re-synced to the channels; can be undone (removed variants come back with their ids). Requires products:write.
Authorization
apiKey Authorization: Bearer nbl_live_... (or nbl_test_... for test mode). Test-mode writes are validated and simulated but never persisted and never touch channels; simulated results are marked simulated.
