Turn client-mapped vehicle inventory into governed Google Merchant and Meta catalogue feeds without leaving XeroFlow.
Map each feed to the exact XeroFlow client and dealership source before it can be delivered. New, demo, and used inventory stay separated, while server-side validation checks the source URL, vehicle counts, client identity, and feed health instead of trusting values copied into a browser form.
XeroFlow reuses the Meta OAuth connection already mapped to the client and checks the permissions Meta actually granted. Catalogue discovery and delivery become available when Meta grants the required catalogue permissions. If app review or a Business Manager role is missing, the platform identifies that exact gate rather than repeatedly asking the operator to reconnect.
When a catalogue already has the intended product feed, operators can select that exact feed by ID. XeroFlow verifies it belongs to the chosen catalogue and fails closed instead of creating a duplicate. The schedule change still requires explicit confirmation, followed by an immediate import and provider readback.
Every attachment records tenant, client, connection, catalogue, source feed, upload identity, schedule, and sanitized provider-readback evidence. Tokens are never copied into the feed ledger. Meta app approval and business-role requirements remain explicit operator gates, and attaching inventory never claims to activate or spend from an advertising campaign.
