Wait — do I need a separate “OnceHub integration” in RevSquared?

No. RevSquared has one generic Zapier integration. You paste one Catch Hook URL into it and you're done on the RevSquared side. The OnceHub part lives entirely inside the Zap you build in Zapier.

Do I need a Zapier account?

Yes. Zapier's free tier covers ~100 tasks/mo.

Can callers complete the booking inside the call?

Most teams pair the AI's verbal scheduling with a follow-up booking link via SMS so the caller finishes picking a time on their phone.

What does the webhook payload look like?

Full call JSON: caller name, phone, email, transcript, AI summary, sentiment, outcome, captured custom fields, recording URL.

Can I customize what data goes where?

Yes — inside Zapier you map any field from the webhook payload to any OnceHub field with point-and-click.

1 hookup

RevSquared has one Zapier integration. Paste one Catch Hook URL and every call posts to it forever.
