MailPace Node.js Utils

Utility function for MailPace, a transactional email service.

verifySignature

Webhook requests for events or incoming emails are signed using Ed25519. This is not exactly straight-forward to implement in Node.js.

import { verifySignature } from "mailpace-utils";

const publicKeyBase64 = process.env.MAILPACE_PUBLIC_KEY; // Copy from MailPace dashboard

const message = <Buffer>; // raw request body
const signature = ""; // `x-mailpace-signature` request header

const isValid = verifySignature({ message, signature, publicKey });

if (!isValid) {
  throw new Error("Invalid signature");
}
