Booked but invisible
The calendar contains the meeting while the assigned seller never receives a CRM record.
Calendly CRM handoff
Make every booked meeting arrive in the sales system exactly once.
Protect booking-to-CRM workflows with stable event identity, contact normalization, bounded retries, and delivery evidence.
A successful automation run is not proof of delivery.
A meeting can be booked while the follow-up CRM workflow times out, rejects a field, or runs twice after a replay. Calendar success is not the same as verified contact and opportunity creation.
Calendly booking event -> LeadProof -> CRM, enrichment, or sales automationReschedule complexity
Invite, cancel, and reschedule events need durable identities and explicit business rules.
Duplicate follow-up
Repeated webhook attempts can create duplicate contacts, tasks, or notifications.
Implementation
Put LeadProof in the delivery path.
Keep the tools that create and process the lead. Standardize only the fragile handoff between them.
Open sandbox instructions →- Send the relevant booking event from your authorized Calendly integration to LeadProof.
- Use the event URI or another durable booking identifier as the Idempotency-Key.
- Set the CRM or sales-automation webhook as the destination.
- Keep the receipt ID beside the booking event for support and reconciliation.

}Questions
What teams ask before adding LeadProof.
Does LeadProof manage the calendar?
No. Calendly remains the booking system; LeadProof protects the downstream lead handoff.
How should reschedules be handled?
Treat each distinct source event according to your workflow rules and use its durable event identifier for idempotency.
Can booking questions be forwarded?
Yes. Include the approved destination fields in the data object sent with the normalized contact.
