patch https://api.developers.deliveroo.com/menu/brands//catalogue//item_unavailabilities/
Once a catalogue is sent to our platform, all the items for the site are theoretically "available", therefore a customer can order them.
This endpoint allows you to set items as "available" or "unavailable", e.g. reflecting items that are out of stock
As unavailabilities will be different for every site, we need both the external ID provided during catalogue upload, and the specific Site ID.
Rate Limit
This endpoint is rate limited at 1 request per second per brand.
