Handle inbound SMS

Handling inbound calls with Nexmo is easy. You just need to create a webhook endpoint and configure your number or account to point to the endpoint.

Prerequisites

• Rent a virtual number

Implement a webhook endpoint

// GITHUB: https://github.com/nexmo-community/nexmo-node-quickstart/blob/master/sms/receive-express.js
// Lines: ALL LINES

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

app.use(bodyParser.json())
app.use(bodyParser.urlencoded({ extended: true }))

app
  .route('/webhooks/inbound-sms')
  .get(handleInboundSms)
  .post(handleInboundSms)

function handleInboundSms(request, response) {
  const params = Object.assign(request.query, request.body)
  console.log(params)
  response.status(204).send()
}

app.listen(3000)

Run your server

Save this file to your machine and run it using the node command:

$ node app.js

You'll need to expose your server to the open internet. During development you can use a tool like Ngrok to do that.

Configure your SMS endpoint with Nexmo

From Nexmo Dashboard go to Settings and enter your endpoint in the field labeled Webhook URL for Inbound Message.

Send your Nexmo number an SMS

Now when you send your Nexmo number an SMS you should see it logged in your console.
