TWRAP

• a convenience wrapper for the Twilio PHP library

---

This is a convenience wrapper for the Twilio SDK library because everyone hates working with arrays, and because I got sick of writing middleware to protect incoming webhooks. The aim is to slowly wrap the generated SDK and return objects wherever possible, starting with the most used endpoints.

Creating a Client

You can use the factory method to create a new instance of the TwrapClient:

$client = \Twrap\Factory::create('MYACCOUNTSID', 'MYSUPERSECRETAUTHTOKEN');

Using the Client

Once you have a client, you can use the lovely methods to get objects back from the API, for example to lookup the details of a messages:

var_dump($client->messageDetails('SM322bd06e7c948e05461cc5c5dea3797b'));

class Twrap\Model\Message#11 (20) {
  public string $body =>
  string(45) "Hello, drop me an email at ghockin@twilio.com"
  public int $numSegments =>
  int(1)
  public string $direction =>
  string(14) "outbound-reply"
  public string $from =>
  string(13) "+447123456789"

    string(26) "2021-03-22 16:23:25.000000"
    public $timezone_type =>
    int(1)
    public $timezone =>
    string(6) "+00:00"
  }

  }
} 

Middleware

A PSR-15 middleware is available that automatically checks the Twilio security header for any requests that have it added. This prevents spoofed requests from Twilio and protects your webhooks from being called by anyone unexpected. You can add it anywhere you can use PSR-15 middleware. For example, in Slim Framework:

<?php

use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Factory\AppFactory;

require __DIR__.'/../vendor/autoload.php';

$app = AppFactory::create();

$client = \Twrap\Factory::create(getenv('TWILIO_DEMO_ACCOUNT_SID'), getenv('TWILIO_DEMO_AUTH_TOKEN'));
$middleware = new \Twrap\Middleware\TwilioWebhookMiddleware($client);

$app->post(
    '/',
    function (Request $request, Response $response, $args) {
        $response->getBody()->write("Hello world!");
        $response = $response->withAddedHeader('Content-Type', 'text/plain');
        $response = $response->withStatus(200);
        return $response;
    }
)->addMiddleware($middleware);

$app->run();
