import { verifyPlainWebhook } from "@team-plain/webhooks";

const result = verifyPlainWebhook(rawBody, signature, secret);

if (result.error) {
  console.error(result.error.message);
} else {
  // result.data is fully typed with the event payload
  const event = result.data;
  console.log(event.eventType, event.payload);
}
