NextJS Twilio Typescript example

text.ts

import { NextApiResponse, NextApiRequest } from "next";
const twillio = require('twilio');
const authToken = process.env.TWILIO_AUTH_TOKEN;
const accountSid = process.env.TWILIO_ACCOUNT_SID;
const myCellPhoneNumber = process.env.MY_NUMBER;
const superSecretAPIKey = 'ABCD1234';

export default async (req: NextApiRequest, res: NextApiResponse) => {
    const client = twillio(accountSid, authToken);
    const auth = req.headers.authorization;
    if (auth === superSecretAPIKey) {
        await client.messages
            .create({
                body: `\n

                from: '+12694754126', // my twilio testing number
                to: `+1${myCellPhoneNumber}`
            })
            .then((message: String) => res.json(message), (err: Error) => res.json(err));
    } else {
        return res.status(401).end();
    }
}

Update: I use tryslater for cron jobs in Next.js now instead.
