I want a fully-automated calling pipeline that links Tabbly with n8n. The flow starts with a CSV upload containing only lead names and phone numbers; the moment I drop that file into a watched folder (or a simple form), n8n should parse it, create individual lead records, and instruct Tabbly to place AI-driven cold calls to each contact. Calls must fire sequentially or in parallel based on a configurable throttle so campaigns scale without hitting rate limits. After every call, n8n should pull the call result, transcript, recording URL, and disposition from Tabbly and write everything back to a central data store—Google Sheets or a lightweight database is fine as long as I can filter, tag, and export results later. Failed numbers need an automatic second attempt after a defined delay, while successful connects should stop further attempts. For campaign management I need: • A dashboard-style sheet or Airtable view showing real-time call status, next-action dates, and basic analytics (contacted, unreachable, converted). • Error handling so malformed rows or missing numbers are logged and skipped without breaking the run. • Simple toggle variables in n8n so I can change the call script ID, daily call cap, and retry logic without touching any code. Deliver the n8n workflow JSON, clear setup instructions, and a quick demo video or screenshare proving the end-to-end loop—from CSV upload to call completion log—runs as intended.
