How do ad tools handle product feed management for large catalogs, like syncing feeds and keeping product ads refreshed when prices or inventory change?

“Meta also supports updating individual catalog items through its API rather than waiting for the next scheduled feed.”

“For example, Google Merchant Center supports scheduled feed fetching and API-based updates.”

“Its Merchant API also supports incremental product updates, meaning you don't have to re-upload thousands of products when only one product's price changes.”

“Google's Merchant API specifically supports this approach through individual product insertions, updates, and deletions.”
