sign static method

String sign({ required String secret, required String id, required DateTime timestamp, required String body, })

Computes the webhook-signature value for a delivery: v1, followed by the base64 signature.

Use it to build signed test requests for your webhook handler.

Implementation

static String sign({
  required String secret,
  required String id,
  required DateTime timestamp,
  required String body,
}) {
  final hmac = _hmacFor(secret);
  final seconds = _unixSeconds(timestamp);
  return 'v1,${_compute(hmac, id, seconds, utf8.encode(body))}';
}
