Payloads are signed using asymmetric A.K.A. public-key cryptography to guarantee the authenticity of delivered callbacks. Each callback delivery request includes an X-Signature header field. This field contains a base64-encoded RSA PKCS#1 v1.5 signature of the SHA256 digest of the request body buffer. You can obtain the public key forDocumentation Index
