01Lead delivery reliability
The controls that keep a captured lead intact, unique, observable, retryable, and verifiably delivered from an authorized source to its intended business system.
LeadProof behaviorLeadProof standardizes normalization, idempotency, bounded retries, destination response verification, receipts, and safe replay around that handoff.
02Stable idempotency key
A source-derived identifier reused for every attempt to deliver the same event, allowing a receiver to recognize a retry instead of creating a duplicate.
LeadProof behaviorProduction delivery requires an Idempotency-Key and returns the existing receipt when the same event is submitted again.
03Eligible transient failure
A temporary transport or destination condition—such as a timeout, rate limit, or eligible server error—that may succeed after a bounded delay.
LeadProof behaviorLeadProof retries only eligible temporary failures; permanent request or validation failures are returned without blind replay.
04Bounded retry
A retry policy with a finite attempt count and controlled delay, preventing an unavailable destination from creating an endless delivery loop.
LeadProof behaviorLeadProof records each attempt and ends with a delivered or delivery_failed receipt after the configured bounds are exhausted.
05Destination verification
Evaluation of the destination HTTP response against the delivery contract instead of treating the outbound request itself as proof of success.
LeadProof behaviorLeadProof records the final response status. It does not claim CRM-specific object creation unless the destination response itself proves that outcome.
06Delivery receipt
A portable record of a delivery event’s identifier, final status, attempt count, destination, timing, and payload fingerprint.
LeadProof behaviorLeadProof returns a receipt to the caller and exposes metadata-only receipt history in the private customer dashboard.
07Payload fingerprint
A one-way SHA-256 digest used to compare request content without intentionally retaining the complete production lead payload.
LeadProof behaviorLeadProof stores the fingerprint with operational metadata and uses it to verify that a replay matches the original failed delivery.
08Safe replay
A new delivery attempt that preserves the original idempotency key and requires matching payload and destination fingerprints.
LeadProof behaviorLeadProof permits replay only for a final failure, only with an explicit replay header, and only when the protected fingerprints match.
09Metadata-only receipt history
Operational delivery history that retains status, timing, source, destination hostname, response, and fingerprints without becoming a second lead database.
LeadProof behaviorLeadProof’s customer dashboard shows operational evidence and never displays stored complete production payloads.
10Public HTTPS destination
An internet-routable HTTPS endpoint without embedded URL credentials, localhost, private-network, link-local, or internal host addressing.
LeadProof behaviorLeadProof rejects production destinations that do not satisfy this boundary before attempting delivery.
11Automatic purchase fulfillment
The assignment of purchased access only after a payment processor sends an authentic event confirming the subscription state.
LeadProof behaviorLeadProof verifies signed Stripe webhook events, assigns the paid plan, and lets the matching verified identity reveal its API key once.
12Subscription access suspension
Automatic disabling of production credentials when the associated paid subscription is no longer active or trialing.
LeadProof behaviorLeadProof suspends access for canceled, unpaid, paused, incomplete, or otherwise inactive subscription states reported by Stripe.
