catalog fields not updating

Hi @tessa, welcome to the group!

I assumed you saw the feed documentation on the pre-conditions here:

• The catalog is a public, hosted feed of all the items in your catalog.
  • If you do not have your own feed hosting location, you can use a service such as Google Merchant feeds.
• The feed is in JSON or XML.  Check out an example feed in JSON and an example feed in XML.
• The data in the feed is only one node deep, not nested JSON or XML (unless it is hosted on Google Merchant Feeds).
• The size of any one feed file should not exceed 100 MB; for optimal performance, we recommend each feed file not exceed 50 MB. If your file exceeds this amount, please split the feed into multiple files. All files used as sources will feed into the same catalog in Klaviyo.
• Required fields must not be left blank. For unavailable numeric fields, pass a zero (0), and for unavailable text fields, pass something indicating this such as “n/a” or “unavailable”.
• If your feed is hosted with a caching layer, disable caching for the location where the feed is hosted or refresh this cache when the feed is updated. Otherwise, Klaviyo will only pull updated data for the feed items after the cache is refreshed.

If the above all looks correct with your feed, a few other things to consider:

• Feed update time - I don’t remember how frequently the feed updates, but it may take time assuming you were checking right away.
• Make sure your feed isn’t cached on your server or where the product feed is sourced - sometime that’s implicit on platforms (e.g. Shopify) or DNS proxies (Cloudflare) or web servers (Varnish, ElasticCache, etc).
• Finally, if all else fails, if it’s possible, try deleting the source and re-adding it and re-mapping the fields (including the new ones).

Hope this helps!
