Express.js দিয়ে SMS Sending API

নিচে একটি simple SMS sending API তৈরি করা হলো, যেখানে client POST request পাঠালে Twilio SMS পাঠাবে।

const express = require("express");
const twilio = require("twilio");
require("dotenv").config();

const app = express();
app.use(express.json());

// Twilio Client Setup
const client = twilio(
    process.env.TWILIO_ACCOUNT_SID,
    process.env.TWILIO_AUTH_TOKEN
);

app.post("/send-sms", async (req, res) => {
    const { to, message } = req.body;

    try {
        const sms = await client.messages.create({
            from: process.env.TWILIO_PHONE,
            to,
            body: message
        });

        return res.json({
            success: true,
            message: "SMS Sent Successfully!",
            sid: sms.sid
        });

    } catch (error) {
        return res.status(500).json({
            success: false,
            error: error.message
        });
    }
});

app.listen(5000, () => console.log("Server running on port 5000"));

Example Client Request (POSTMAN / Frontend)
