A successful n8n execution can still end with a lead that never reached the CRM.
In a local n8n 2.47.3 demo with a mock CRM, all eight webhook executions finished with status “success”. One of those requests exhausted all three write attempts. The caller received HTTP 503, no event was stored for that request, and one alert reached the local alert sink. The workflow had handled the failure, so the execution itself completed successfully.
For a lead-intake workflow, test these three outcomes separately: • First delivery: one lead, one event and one review task. • Same event and business data replayed: HTTP 200, outcome “replayed”, still one of each. Compare the stored values too, not only the counts. • All write attempts fail: a failure response to the caller, no unintended write, and an alert someone can act on.
Those were the observed results in this demo. The replay preserved the original lead and event rows; the failure case left the existing records unchanged.
Before handing a workflow to an operations team, agree what “delivered” means in the destination system and test the exhausted-retry path. An execution-success count alone can miss failed deliveries that the workflow handles deliberately.
