Introduction to Caller-ID

The Caller-ID API is an essential tool for applications that need to manage, identify, and authenticate incoming calls. This guide will explore various APIs provided by Caller-ID and how you can integrate them into your application seamlessly.

API Examples

1. Fetch Caller Information

This API retrieves detailed information about the caller based on the phone number provided.

  GET /api/callerinfo?phoneNumber=
  Response:
  {
    "name": "John Doe",
    "location": "New York, USA",
    "carrier": "Verizon"
  }

2. Block Specific Callers

This API allows you to block specific phone numbers to prevent them from calling your application.

  POST /api/blockCaller
  Body:
  {
    "phoneNumber": ""
  }
  Response:
  {
    "status": "Success",
    "message": "Caller blocked successfully"
  }

3. Unblock a Caller

If you want to remove a phone number from the block list, use this API.

  POST /api/unblockCaller
  Body:
  {
    "phoneNumber": ""
  }
  Response:
  {
    "status": "Success",
    "message": "Caller unblocked successfully"
  }

4. Call Recording and Retrieval

You can record calls to analyze or retrieve later with the help of this API.

  POST /api/recordCall
  Body:
  {
    "callSid": ""
  }
  Response:
  {
    "status": "Success",
    "message": "Call recording started"
  }
  ---
  GET /api/recording?callSid=
  Response:
  {
    "recordingUrl": "http://example.com/recordings/.mp3"
  }

App Example with Caller-ID APIs

Let’s create a mini-application that uses the Caller-ID APIs to manage incoming calls.

  const express = require('express');
  const app = express();

  app.get('/callerinfo', (req, res) => {
    const phoneNumber = req.query.phoneNumber;
    // Fetch caller information from caller-id API
    // Mock response
    res.json({
      "name": "John Doe",
      "location": "New York, USA",
      "carrier": "Verizon"
    });
  });

  app.post('/blockCaller', (req, res) => {
    const phoneNumber = req.body.phoneNumber;
    // Block caller using caller-id API
    // Mock response
    res.json({
      "status": "Success",
      "message": "Caller blocked successfully"
    });
  });

  app.post('/unblockCaller', (req, res) => {
    const phoneNumber = req.body.phoneNumber;
    // Unblock caller using caller-id API
    // Mock response
    res.json({
      "status": "Success",
      "message": "Caller unblocked successfully"
    });
  });

  app.listen(3000, () => {
    console.log('Caller-ID app is running on port 3000');
  });

By integrating these APIs, you can enhance the functionality of your application and deliver a better user experience.
