VerifyMyContent Video Moderation PHP SDK

PHP SDK to use the VerifyMyContent Video Moderation service.

Installation

composer require verifymycontent/video-moderation

Get Started

The main class to handle the moderation integration process is the VerifyMyContent\VideoModeration\Moderation. It will abstract the HMAC generation for the API calls.

Start a Moderation

Use the start method to create a moderation, like the example below:

<?php

require(__DIR__ . "/vendor/autoload.php");

$moderation = new VerifyMyContent\VideoModeration\Moderation(getenv('VMC_API_KEY'), getenv('VMC_API_SECRET'));
//$moderation->useSandbox();

$response = $moderation->start(new \VerifyMyContent\SDK\ContentModeration\Entity\Requests\CreateStaticContentModerationRequest([
  "content" => [
    "type" => "video",
    "external_id" => "YOUR-VIDEO-ID",
    "url" => "https://example.com/video.mp4",
    "title" => "Uploaded video title",
    "description" => "Uploaded video description",
  ],
  "webhook" => "https://example.com/webhook",
  "customer" => [
    "id" => "YOUR-CUSTOMER-UNIQUE-ID",
    "email" => "person@example.com",
    "phone" => "+4412345678"
  ]
]));

// save $response->id if you want to call the moderation status endpoint later

// redirect uploader to check identity
header("Location: {$response->redirect_url}");

Retrieve Moderation by ID

Retrieves a specific moderation to get current status. Example:

<?php

require(__DIR__ . "/vendor/autoload.php");

$moderation = new VerifyMyContent\VideoModeration\Moderation(getenv('VMC_API_KEY'), getenv('VMC_API_SECRET'));
//$moderation->useSandbox();

$response = $moderation->get($moderationID);

// Printing current status
echo "Status: {$response->status}";

Live Stream

To moderate a live stream broadcast you'll need to use different APIs as described below.

Create a Live Stream Moderation

Use the createLivestream method to create a live stream moderation, like the example below:

<?php

require(__DIR__ . "/vendor/autoload.php");

$moderation = new VerifyMyContent\VideoModeration\Moderation(getenv('VMC_API_KEY'), getenv('VMC_API_SECRET'));
//$moderation->useSandbox();

$response = $moderation->createLivestream(new \VerifyMyContent\SDK\ContentModeration\Entity\Requests\CreateLiveContentModerationRequest([
  "external_id" => "YOUR-LIVESTREAM-ID",
  "embed_url" => "https://example.com/live/",
  "title" => "Live stream title",
  "description" => "Live stream description",
  "webhook" => "https://example.com/webhook",
  "stream" => [
      "protocol" => "webrtc",
      "url" => "https://example.com/live/",
  ],
  "customer" => [
      "id" => "YOUR-CUSTOMER-UNIQUE-ID",
      "email" => "person@example.com",
      "phone" => "+4412345678"
  ]
]));

// save $response->id to start live stream later

// redirect uploader to check identity
header("Location: {$response->login_url");

Start a created Live Stream Moderation

When you receive the webhook with the status Authorised, it means you can now start to broadcast a live stream, you can then use the startLivestream method to trigger the moderation:

<?php

require(__DIR__ . "/vendor/autoload.php");
    
$moderation = new VerifyMyContent\VideoModeration\Moderation(getenv('VMC_API_KEY'), getenv('VMC_API_SECRET'));
//$moderation->useSandbox();

$success = $moderation->startLivestream($_GET['id'], new \VerifyMyContent\SDK\ContentModeration\Entity\Requests\StartLiveContentModerationRequest([
    "embed_url" => "https://example.com/live-stream-embed",
    "stream" => [
        "protocol" => "rtmps",
        "url" => "rtmps://your-server:443/your-video-stream"
    ],
]));
var_dump($success === true);

Note: You'll have a limit of time to send this request after you received the webhook notifying the user was authorised to start the broadcast.

Updating Live Stream moderation rules

This endpoint allows you to update the moderation rules for a specific live stream

<?php

require(__DIR__ . "/vendor/autoload.php");
    
$moderation = new VerifyMyContent\VideoModeration\Moderation(getenv('VMC_API_KEY'), getenv('VMC_API_SECRET'));
//$moderation->useSandbox();

$success = $moderation->changeLivestreamRule($_GET['id'], new \VerifyMyContent\SDK\ContentModeration\Entity\Requests\ChangeLiveContentRuleRequest([
  "rule" => "no-nudity"
]));
var_dump($success === true);

Complaint Resolution

To start a complaint for previously uploaded content. You need to send the original content and the violations raised by the user.

Create a Complaint Moderation

Use the createComplaintModeration method to create a complaint moderation, like the example below:

<?php

require(__DIR__ . "/vendor/autoload.php");

$moderation = new VerifyMyContent\VideoModeration\Moderation(getenv('VMC_API_KEY'), getenv('VMC_API_SECRET'));
//$moderation->useSandbox();

$response = $moderation->createComplaintModeration(new \VerifyMyContent\SDK\Complaint\Entity\Requests\CreateStaticContentComplaintRequest([
   "content" => [
      "description" => "Your description", 
      "external_id" => "YOUR-VIDEO-ID", 
      "tags" => [
          "VIOLATION_1" 
      ], 
      "title" => "Your title", 
      "type" => "video", 
      "url" => "https://example.com/video.mp4" 
   ], 
   "customer" => [
      "id" => "YOUR-USER-ID" 
   ], 
   "webhook" => "https://example.com/webhook" 
]));

var_dump($response);

Create a Live Stream Complaint Moderation

Use the createComplaintLivestream method to create a live stream complaint moderation, like the example below:

<?php

require(__DIR__ . "/vendor/autoload.php");

$moderation = new VerifyMyContent\VideoModeration\Moderation(getenv('VMC_API_KEY'), getenv('VMC_API_SECRET'));
//$moderation->useSandbox();

$response = $moderation->createComplaintLivestream(new \VerifyMyContent\SDK\Complaint\Entity\Requests\CreateLiveContentComplaintRequest([
   "complained_at" => "2022-11-04T12:04:08.658Z", 
   "customer" => [
      "id" => "YOUR-USER-ID" 
   ], 
   "stream" => [
      "external_id" => "YOUR-LIVESTREAM-ID", 
      "tags" => [
        "VIOLATION_1" 
      ]
   ], 
   "webhook" => "https://example.com/webhook" 
]));

var_dump($response);

Create a Consent Complaint

Use the createComplaintConsent method to create a complaint consent moderation, like the example below:

<?php

require(__DIR__ . "/vendor/autoload.php");

$moderation = new VerifyMyContent\VideoModeration\Moderation(getenv('VMC_API_KEY'), getenv('VMC_API_SECRET'));
//$moderation->useSandbox();

$response = $moderation->createComplaintConsent(new \VerifyMyContent\SDK\Complaint\Entity\Requests\CreateConsentComplaintRequest([
   "content" => [
      "external_id" => "YOUR-VIDEO-ID" 
   ], 
   "customer" => [
      "id" => "YOUR-USER-ID" 
   ], 
   "webhook" => "https://example.com/webhook"
]));

var_dump($response);

Webhook Security

In order to confirm that a webhook POST was sent from VerifyMyContent, we provide a helper class to validate that the Authorization header was sent correctly. Example:

<?php
require(__DIR__ . "/vendor/autoload.php");

// get request body
$body = file_get_contents('php://input');
// get headers
$headers = getallheaders();
// instantiate VerifyMyContent helper class
$hmac = new VerifyMyContent\Commons\Security\HMAC(getenv('VMC_API_KEY'), getenv('VMC_API_SECRET'));
// validate hmac Authorization
if(!array_key_exists('Authorization', $headers) || !$hmac->validate($headers['Authorization'], $body)) {
  die("This request did not come from VerifyMyContent");
}
// you can do your logic now, the webhook was called from VerifyMyContent.
var_dump($body);
