Hey mate, that’s def doable in n8n. I’d prob keep it simple:
FB lead trigger → format lead → send SMS via Retell → wait 10 mins → if no reply, trigger AI call → check Google Calendar → book via Cal.com → push lead + appt into JobTread.
Main thing is making sure phone formatting and booking logic are solid so nothing breaks.
do you already have the FB leads hitting n8n, or is that part not set up yet?
