最近、トンネリングツールとしてngrokやserveoの代わりにlocaltunnelを使っています。

npmでインストールします。

npm install -g localtunnel

グローバルインストールするとCLIツールが使えてltコマンドでサクッとトンネリングできます。

lt --port 3000

応答でパブリックなURLが返ります。

your url is: https://example.com

あとはNode.jsでローカルにサーバを立てて

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

app.use(bodyParser.json());
app.post('/', (req, res) => {
    console.log(req.body);
    res.status(200);
})

app.listen(3000);

起動します。

node app.js

localtunnelで発行されたURLをSendGridのEvent Webhookにセットします。

Test Your Integrationボタンを押すとEventを受信できます。お手軽です。
