Webhook ownership: one inbox, one team
Shared webhook endpoints without a named owner become everyone’s problem and nobody’s priority when signatures fail at 2 a.m.
Webhooks look simple: an HTTP endpoint, a signature header, a payload. Operationally they are a product surface. When three squads share one URL “for convenience”, signature rotations and replay handling stall because no backlog owns them.
Name an owner before go-live
OakCore’s cutover checklists include a named owner for each inbound webhook, a documented verification library (not a one-off snippet), and a replay strategy that does not require SSH into production.
Separate receive from process
Receiving and acknowledging quickly, then processing asynchronously, keeps partner retries from stacking on slow downstream work. That pattern belongs in the contract map, not as a late “performance fix”.
If your logs already show signature failures or duplicate deliveries, start with an Integration Audit rather than a full redesign. Often the fix is ownership and a short remediation sprint — not a new architecture story.
