FAQ

Questions we get

Do I need a developer?

For the raw API, a minimum, yes. Otherwise, the Zapier and Make integrations cover most connections without a single line of code — Google Sheets, Slack, HubSpot, and the rest.

Which events exactly fire a webhook?

Missed call, handled call, completed qualification, appointment created or cancelled, STOP received, follow-up sent. The full list is in the docs, with a sample payload per event.

Is the API included in the $149/mo?

Yes — webhooks and API are included, with no surcharge and no hidden tier. There's a sensible rate limit per line to prevent abuse, but no normal usage ever gets near it.
