Frequently asked

The moment a customer’s message matches this flow’s trigger keyword(s) — not after every message in the conversation, and not tied to a specific button or question inside the flow.
Yes — Forward Data to Webhook and Sync Data to Google Sheets are separate fields in the same Data & Integrations section and can both be filled in.
No — this fires on the keyword match itself. A button inside the flow has its own separate webhook field — see Webhook on Button Click.
