Receiver - Upstash Documentation

When receiving a message from QStash, you should verify the signature. The QStash Typescript SDK provides a helper function for this.

import { Receiver } from "@upstash/qstash";const receiver = new Receiver({  currentSigningKey: "YOUR_CURRENT_SIGNING_KEY",  nextSigningKey: "YOUR_NEXT_SIGNING_KEY",});// ... in your request handlerconst signature = req.headers["Upstash-Signature"];const body = req.body;const isValid = await receiver.verify({  body,  signature,  url: "YOUR-SITE-URL",});
