Webhooks Lie by Omission
A webhook is a promise a platform makes in the moment, and like most promises made in a hurry, it occasionally does not arrive. Endpoints time out, deploys eat events, a retry queue gives up quietly at 3 a.m. None of this is malice. All of it means the same thing for a system built on events alone: your picture of reality has holes, and the holes are exactly where the weird failures live.…
Webhooks are a promise made by platforms, often incomplete or absent. Endpoints can time out, deployments can consume events, and retry queues may fail silently in the middle of the night. This lack of information creates gaps in a system that relies solely on events. Recovery processes must account for these gaps, as a missed failure event means a subscriber failed to be saved.
Swipe Again handles events as the primary path, but also incorporates reconciliation sweeps to read platform records and compare them to their own. These sweeps run ninety days after connection, establishing a factual baseline before any live events occur. By acknowledging that webhooks may omit information, Swipe Again ensures that any resulting system may appear calm and green, but is actually accurate.
The recovery flow assumes that all inputs are missing information, creating a redundant backup source of truth. This meticulous approach allows the system to present reliable numbers.
