Number Insight Advanced Webhook

This code snippet shows you how to code the webhook handler that receives the data returned by an asynchronous call to the Number Insight Advanced API. See the Number Insight Advanced code snippet to learn how to code the initial request for the insight data.

Before attempting to run the code examples, replace the variable placeholders as instructed in replaceable variables.

Prerequisites

Install dependencies

npm install express body-parser
Initialize your dependencies

Create a file named ni-advanced-async.js and add the following code:

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

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

Write the code

Add the following to ni-advanced-async.js:

Copy to Clipboard
app.post('/webhooks/insight', handleInsight)

function handleInsight(request, response) {
  console.log("params", Object.assign(request.query, request.body))
  response.status(204).send()
}

app.listen(3000)

Prerequisites

Install dependencies

Add the following to `build.gradle`:

compile 'com.nexmo:client:5.2.1'
compile 'com.sparkjava:spark-core:2.7.2'

Write the code

Add the following to the main method of the AsyncInsightTrigger class:

Copy to Clipboard
port(3000);
Spark.post("/webhooks/insight", (req, res) -> {
    AdvancedInsightResponse response = AdvancedInsightResponse.fromJson(req.body());
    System.out.println("Country: " + response.getCountryName());

    res.status(204);
    return "";
});

Run your code

We can use the application plugin for Gradle to simplify the running of our application. Update your build.gradle with the following:

  apply plugin: 'application'
  mainClassName = project.hasProperty('main') ? project.getProperty('main') : ''

Run the following gradle command to execute your application, replacing com.nexmo.quickstart.insight with the package containing AsyncInsightTrigger:

gradle run -Pmain=com.nexmo.quickstart.insight.AsyncInsightTrigger
