Unsafe retry rules
Retrying permanent client errors can create load without making delivery more likely.
Webhook retry API
Retry failed lead webhooks without creating duplicate records.
Use a bounded webhook retry API with stable idempotency, destination verification, receipts, and an explicit recovery path.
A successful automation run is not proof of delivery.
A generic HTTP retry can make a temporary outage worse. Retrying every response wastes capacity, while generating a new event ID on every attempt can create duplicate contacts and notifications. A reliable policy must distinguish temporary failures, preserve event identity, and record the final destination outcome.
Form, agent, or automation -> retry API -> CRM or public HTTPS webhookDuplicate side effects
A repeated request without stable identity may create the same contact or task more than once.
No final outcome
A retry loop without a receipt leaves operators unable to prove which attempt succeeded.
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 →- Assign one durable Idempotency-Key to the original source event.
- Send the lead and public HTTPS destination to the LeadProof production endpoint.
- Let LeadProof retry eligible network, rate-limit, and server failures with bounded attempts.
- Store the returned receipt and use explicit fingerprint-verified replay only after a final failure.

}Questions
What teams ask before adding LeadProof.
Which responses should be retried?
LeadProof retries network failures, 429 rate limits, and server errors. It does not repeatedly send most permanent 4xx responses.
How many attempts are made?
The production endpoint uses up to three total attempts for an eligible new delivery.
How do I retry a final failure?
Resubmit the identical body and destination with the original Idempotency-Key and X-LeadProof-Replay: true. LeadProof verifies the stored fingerprints first.
