Event is not defined nodejs

I am receiving a webhook from patreon, and when I fire the test, I get this error:

(node:636) UnhandledPromiseRejectionWarning: ReferenceError: event is not defined

This is the code I have

const express = require('express');
const bodyParser = require('body-parser');
const app = express();

app.post('/', async (req, res) => {
    let crypto = require('crypto');

    let hash = event.headers['X-Patreon-Signature'],
        hmac = crypto.createHmac("md5", 'patreon-secret-removed ;)'); 

    hmac.update(event.body);

    let crypted = hmac.digest("hex");

    if (crypted === hash) {
        console.log("That's good hash! " + hash);
    } else {
        console.log("Bad hash! " + hash + " crypted " + crypted);
    }
})
app.listen(8080)

How would I replace event or define it?

Solution

  • let hash = event.headers['X-Patreon-Signature'] << what is event?

    Maybe it's a req, not an event.
