[null,null,["最后更新时间 (UTC):2025-07-26。"],[],["The product feed, used to provide Google with a list of \"things to do\" products, accepts JSON format uploads, optionally compressed. Large product sets can be split across multiple files (shards), each with `FeedMetadata`. `FeedMetadata` includes a shared `nonce`, `total_shard_count`, and unique `shard_id` values. Each `Product` object requires a unique ID, title, and at least one `Option`. Adding or removing products involves uploading an updated feed, as only snapshot processing is supported.\n"]]
