update_openai_ads_feed_products

Update the PRICE, TITLE or AVAILABILITY of variants already in a ChatGPT Ads product feed — send only what changed instead of re-uploading the catalog. This is what stops a stale feed serving ads for out-of-stock items. Pass feedId and products:[{id, variants:[{id, title?, price?:{amount,currency}, availability?:{available|status}}]}], where products[].id is the PARENT product id and variants[].id the existing variant id, both from the catalog already in the feed. price.amount is an INTEGER IN MINOR UNITS — 8999 means $89.99 — so a decimal is a hundredfold error in the price you advertise, and is refused. IT UPDATES EXISTING VARIANTS ONLY: it never creates a feed, uploads a catalog, or adds a product that is not already there. ACCEPTED IS NOT LIVE — OpenAI applies the change asynchronously and returns no completion timestamp and no downstream result, so an out-of-stock product keeps serving until it propagates; say that rather than reporting it as done. A 403 naming product_feed_api_disabled / product_feed_delta_api_disabled means the ACCOUNT lacks Feeds access — nothing about the request was wrong and retrying it unchanged will not help. A 404 means the feed id is wrong, the feed is not linked to this ad account, or Feeds is not enabled.
