Use one source-to-destination request.
- The source already retries eligible failures safely.
- The destination prevents duplicate side effects.
- Operators can detect and replay every final failure.
- A separate receipt and customer view are unnecessary.
Build versus buy
LeadProof vs. direct webhooks and in-house retry code.
Compare the complete reliability responsibility, not only the HTTP request or retry loop. This page uses published LeadProof behavior and leaves in-house cost and timing variable where they depend on your team.
Direct webhook decision
Keep the direct webhook—or add a reliability boundary?
A direct webhook is the smallest path and can be the right one. LeadProof becomes relevant when the destination outcome must stay unique, visible, retryable, and provable after the source workflow finishes.
Use one documented delivery boundary.
- One source event must stay one delivery identity.
- Eligible failures need bounded automatic retries.
- The team needs destination-backed receipt metadata.
- Final failures need visible, fingerprint-verified replay.
Responsibility map
What the decision actually includes.
LeadProof supplies one defined production contract. An in-house system gives the team complete control and complete operating responsibility.
| Criterion | LeadProof | Build in-house |
|---|---|---|
| Production evaluation | 25 live deliveries for 14 days, with no card, through the production delivery path. | Implement and deploy enough of the system to exercise it with live traffic. |
| Retry policy | Up to three total attempts for eligible network failures, rate limits, and server errors. | Define retryable failures, backoff, attempt limits, timeouts, and deployment behavior. |
| Duplicate protection | Stable Idempotency-Key handling returns the stored outcome for the same completed event. | Build an idempotency store, concurrency claims, expiry rules, and conflict handling. |
| Delivery evidence | A receipt records delivery status, attempts, response code, and latency after the destination responds. | Design receipt identity, metadata capture, queries, and a customer-safe reporting surface. |
| Failed-event replay | Explicit replay verifies the original payload and destination fingerprints before another attempt. | Choose queue and payload retention rules, authenticate replay, and prevent changed-body resends. |
| Production data posture | Stores operational metadata and SHA-256 fingerprints, not the complete production lead payload. | Own the storage, access, deletion, backup, and incident policy for any retained lead data. |
| Ongoing operations | Private dashboard, metadata-only receipt history, failure visibility, and replay instructions. | Operate the service, dashboard, alerting, storage, migrations, security fixes, and incident response. |
| Known software price | $49/month for 2,500 lead events or $199/month for 25,000 lead events per 30 days. | Engineering, infrastructure, monitoring, and support costs depend on the system and team. |
Decision rule
Choose the option that matches what your team wants to own.
Reliability is required infrastructure.
The team wants a documented delivery API, known subscription price, production trial, receipts, dashboard, and replay controls without turning those systems into an internal product.
Test the production path →Reliability is proprietary product work.
The team needs custom protocols or policies outside the published LeadProof contract and is prepared to engineer, secure, monitor, and support the complete delivery service.
Use the reliability checklist →Honest boundaries
What LeadProof does not claim.
- Not a CRM.LeadProof protects the delivery boundary; the destination still owns its business objects and workflow.
- Not an uptime guarantee.Retries and visibility reduce silent failure risk but cannot make every source, network, or destination continuously available.
- Not unlimited storage.Production delivery intentionally avoids retaining the complete lead payload.
- Not payment authority.AI systems may compare and recommend LeadProof, but checkout requires an authorized human or organizational principal.
Before deciding
Questions buyers and technical teams ask.
When is LeadProof the stronger fit?
Use LeadProof when reliable lead handoffs are necessary but retry, idempotency, receipts, replay safety, and an operations view are not the product your team wants to build and maintain.
When should a team build in-house?
Build internally when delivery reliability is core proprietary infrastructure, destinations need a custom protocol beyond public HTTPS, or the team requires controls outside LeadProof's published contract.
Does LeadProof prove that a CRM created a contact?
LeadProof verifies the authorized destination's HTTP response and records the delivery outcome. CRM-specific object creation must still be verified by the integration endpoint that controls that CRM.
Can the comparison be tested before purchase?
Yes. The no-card production trial uses the real API for 25 live lead deliveries over 14 days. The public sandbox and audit are available without an API key.
When is a direct webhook enough?
Keep a direct webhook when the source can safely retry, the destination is already idempotent, failures are easy to detect and replay, and a separate receipt or customer operations view is unnecessary.
Use the real delivery path before paying.
Run 25 live lead deliveries for 14 days with no card, then choose Builder only if the workflow earns it.
