Deprecated as of January 2026. The Health & Wellness category events should not be used for new or existing setups. Use a clean pixel with domain aliasing and optimize on the standard Purchase event instead. The mappings are kept here for reference only — for example, to identify UPSTACK_HW_* events in older pixels and historical reports.
What replaced them
Health & Wellness stores now send standard events — purchase, add_to_cart, initiate_checkout and the rest of the standard events — to a clean Meta pixel through domain aliasing, server-side only, with product data sanitized. Campaigns optimize on the standard Purchase event. Nothing needs approving in Meta Events Manager.
Do not recreate these names with global or destination event mappings.
Legacy event names (reference only)
Before January 2026, the Health & Wellness container renamed Meta standard events to the custom names below. You may still see them in older pixels, custom conversions, saved column presets and historical reports.
Moving off the legacy events
If a campaign still optimizes on a UPSTACK_HW_* event, move it to the standard Purchase event on your clean pixel, then update any custom conversions and Ads Manager column presets that reference the old names.
