Webhook & Partner Surface Audit
Stress-test callbacks, partner APIs, and shared secrets that sit on the edge of your payment stack.
Partner webhooks and shared integration endpoints are frequent sources of forged events, secret leakage, and silent privilege expansion.
We review signature verification, replay protection, IP allowlists, secret rotation, and the privileges each partner credential can exercise.
Findings focus on what an attacker or compromised partner could do with a single leaked key or unauthenticated callback.
What is included
- Partner and webhook inventory
- Signature and replay-control review
- Secret lifecycle assessment
- Privilege minimisation recommendations
