How this service works
BitBooth Webhook Signature Verify: pay 0.005 USDC, verify a webhook signature against the provider's canonical HMAC scheme. Supports stripe, github, vercel, cdp, slack, and generic HMAC-SHA256. Constant-time compare, clock-skew tolerance on timestamp-bearing providers (Stripe / Slack / CDP). Stateless — caller supplies their secret in the request body, we never store it.
Output
Returns a structured JSON response indicating whether the webhook signature is valid (boolean), the provider matched, and any error detail if the verification fails. Uses constant-time comparison to prevent timing attacks and applies clock-skew tolerance for timestamp-bearing providers like Stripe, Slack, and CDP.
Example use cases
Stripe payment webhook authenticity check
“I just received a webhook from Stripe and want to make sure it's legitimate before processing the payment — can you verify it using the raw body, the Stripe-Signature header 't=1714050000,v1=def456...', and my webhook secret 'whsec_testABC'?”
GitHub Actions event validation
“Verify this GitHub webhook payload for me — the raw body is the JSON push event, the X-Hub-Signature-256 header is 'sha256=abc123def456', and my GitHub webhook secret is 'gh_secret_myrepo'.”
Slack event subscription verification
“I'm getting Slack events sent to my endpoint and need to confirm they're really from Slack — can you validate the signature using the raw body, the X-Slack-Signature header 'v0=abc...', the X-Slack-Request-Timestamp '1714050000', and my Slack signing secret 'slack_signing_secret_xyz'?”
Technical details
Endpoint
POSThttps://app.heinrichstech.com/v1/cdp/webhook-sig-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to cryptographically verify that an incoming webhook genuinely originated from a known provider (Stripe, GitHub, Vercel, CDP, Slack) or any generic HMAC-SHA256 scheme. It is stateless, meaning your secret never persists server-side. Prefer this over rolling your own HMAC verification when you need constant-time comparison and built-in timestamp/clock-skew handling for Stripe, Slack, and CDP.
Side effects
- Invalid or mismatched signature returns verification failed with false result
- Expired timestamp (outside tolerance window) returns clock-skew error for Stripe/Slack/CDP
- Unsupported provider name returns error indicating unknown scheme
- Malformed or missing signature header returns parsing error
- Wrong secret supplied returns signature mismatch without exposing the correct secret
