Steps From the Dev Dashboard, configure a webhook on your app with an HTTPS endpoint URL and select event types such as entry_sign_in Receive the POSTed JSON body, which contains an 'event' name and a 'payload' representing the Entry or Invite object Recompute a SHA-256 HMAC of the raw request body using your app's client secret and compare it (base64) against the X-Envoy-Signature header Parse the Entry payload for signee name, email, and sign-in responses when the event is entry_sign_in Respond with a 2xx status promptly to acknowledge receipt and avoid retry storms Known gotchas Signature verification must be computed over the exact raw request body — re-serializing the parsed JSON before hashing will produce a mismatch The event catalogue includes many types beyond sign-in (entry_sign_out, invite_created, qr_code_sent, etc.); filter for the ones you actually need
