Secure your AI agent's webhook against forged requests

Verifies every incoming request's signature and freshness before your AI agent processes it, blocking forged or replayed calls.

How the work actually flows

It branches. Exactly one path is taken.

The problem it solves

If you expose an AI agent through a public web address, anyone who finds it can send fake or altered requests, and standard login checks won't catch a tampered payload or an old request being replayed. That leaves your automation open to abuse.

Who it fits

Businesses running an AI agent or automation that's reachable from the internet.

How it works

  1. An incoming request arrives with a signature and timestamp
  2. The system checks that the timestamp is recent, rejecting old or replayed requests
  3. The request's signature is verified to confirm it hasn't been tampered with
  4. The payload is checked against a strict list of allowed fields
  5. Only requests that pass every check are handed to your AI agent
What you get

Forged requests that never get through

Your AI agent's webhook checks every incoming request's signature and freshness, so forged or replayed calls never get processed.

What you get

A verified, untampered request reaching your AI agent, or a rejection for anything suspicious.

What you need

Your existing webhook setup plus a shared secret key and an OpenAI API key.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
