Capture is not delivery
A stored Leadpages submission does not prove the external CRM or follow-up system accepted the same event.
Leadpages form CRM delivery
Keep every Leadpages form submission on a verified path to sales.
Protect Leadpages form webhooks with a secret-checking adapter, stable delivery identity, duplicate-safe retries, and a CRM-bound receipt.

A successful automation run is not proof of delivery.
A Leadpages page can capture and retain a submission while the external webhook or CRM-bound workflow still times out, rejects a field, or is replayed into another record. The team needs a delivery outcome that follows the handoff beyond the landing-page conversion.
Leadpages form submission -> secret-checking adapter -> LeadProof -> CRM, email platform, or sales queueDuplicate recovery
A manual or automated resend can create another destination record when the original submission identity is not preserved.
Exposed ingress
A custom webhook receiver needs to enforce the configured secret before it accepts fields or starts the downstream handoff.
Implementation
Put LeadProof in the delivery path.
Keep the tools that create and process the lead. Standardize only the fragile handoff between them.
Platform reference: Leadpages: Connecting your integrations ↗Open sandbox instructions →- Configure the Leadpages webhook for form-submission events and scope it only to the approved pages.
- Set a Leadpages Secret Key and validate the configured secret in the receiving adapter before mapping any submitted fields.
- Use an immutable submission or webhook event identifier as the LeadProof Idempotency-Key, preserving the same value for every retry.
- Send only approved contact fields to the authorized destination and store the LeadProof receipt beside the originating Leadpages submission.

}Questions
What teams ask before adding LeadProof.
Does LeadProof need the Leadpages Secret Key?
No. Keep the Secret Key inside the receiving adapter or secret manager. LeadProof receives the normalized delivery request and public HTTPS destination, not the Leadpages secret.
Does LeadProof replace Leadpages integrations?
No. Leadpages remains the landing-page and capture system. LeadProof protects the external delivery boundary after the form is submitted.
Can the workflow still use Zapier?
Yes. Keep Zapier or another authorized adapter in the path, preserve one stable submission identity, and use LeadProof for the final duplicate-safe destination handoff and receipt.
