Creates a new secret key to be used to sign all webhook requests.
All subsequent wehook requests sent will include a HMACSHA256 hash that has been Base64 encoded in the X-HMAC-SHA256-Signature
header. Comparing this hashed value against a SHA256 hash of the request body (using the secret as a key) enables you to verify the payload has not been tampered with.
