What it does for you
Signed incoming webhooks, no duplicates or replays
A poorly protected webhook accepts fake messages or processes the same payment twice. This Skill writes or audits your endpoint in the right order: HMAC signature, timestamp, unique ID, fast reply, with tested Node.js and Python templates.
- Reject forged calls and replayed messages
- Handle each event only once, never twice
- Start from tested, dependency-free templates
