Manual check-in fails because it depends on someone available at the wrong time — often after 10pm, between Airbnb threads and a key box.
Automation is not “more WhatsApp”. It is order: booking → pre-check-in link → opt-in + phone → access template → delivery proof → fallback if the channel blocks.
OTA iCal gives dates, rarely phones. First touch stays in OTA messaging: paste the Kyvvio link. Guests fill in; Cloud API takes over after.
Ops gain: fewer code calls, visible states in /ops, Relancer without improvisation. Premium includes plan B when Meta rejects a template.
