  "guid": "cometchat-guid-1",
  "slowDownTimeInMS": 660000
}).then(response => {
  // Success
}).catch(error => {
  // Error
});
Disable Slow Mode 
CometChat.callExtension('slow-mode', 'DELETE', 'v1/configure', {
  "guid": "cometchat-guid-1"
}).then(response => {
  // Success
}).catch(error => {
  // Error
});
Fetch Slow Mode Details 
const guid = "cometchat-guid-1";
CometChat.callExtension('slow-mode', 'GET', `v1/fetch-configuration?guid=${guid}`, null)
  .then(response => {
    // { isSlowed, slowDownTimeInMS, lastMessageSentAtTimestamp }
  });

​
Data Masking Filter

Hide phone numbers, email addresses, and other sensitive information in messages. Settings
  1. Enable the extension
  2. Configure default masks (Emails, SSN, US phone numbers)
  3. Add custom regex patterns for additional masking
Response Format 
{
  "@injected": {
    "extensions": {
      "data-masking": {
        "data": {
          "sensitive_data": "yes",
          "message_masked": "My number is ***** & my email id is ****"
        }
      }
    }
  }
}
Implementation 
var metadata = message.getMetadata();
if (metadata != null) {
  var injectedObject = metadata["@injected"];
  if (injectedObject?.extensions?.["data-masking"]) {
    var dataMaskingObject = injectedObject.extensions["data-masking"]["data"];
    var message_masked = dataMaskingObject["message_masked"];
  }
}

​
Profanity Filter

Mask or hide profanity in messages using a customizable blacklist. Settings
  1. Enable the extension
  2. Optionally enable “Drop messages with Profanity”
  3. Add comma-separated list of words to filter (supports emojis)
Response Format 
{
  "@injected": {
    "extensions": {
      "profanity-filter": {
        "profanity": "yes",
        "message_clean": "This is ****"
      }
    }
  }
}
Implementation 
var metadata = message.getMetadata();
if (metadata != null) {
  var injectedObject = metadata["@injected"];
  if (injectedObject?.extensions?.["profanity-filter"]) {
    var profanityFilterObject = injectedObject.extensions["profanity-filter"];
    var cleanMessage = profanityFilterObject["message_clean"];
  }
}

​
Image Moderation

AI-powered image moderation to detect unsafe content. Images are classified into:
  • Explicit Nudity
  • Suggestive Nudity
  • Violence
  • Visually Disturbing
Response Format 
{
  "@injected": {
    "extensions": {
      "image-moderation": {
        "unsafe": "yes",
        "confidence": "99",
        "category": "explicit_nudity"
      }
    }
  }
}
A confidence value less than 50 is likely a false-positive. Implementation 
const metadata = message.getMetadata();
if (metadata != null) {
  const injectedObject = metadata["@injected"];
  if (injectedObject?.extensions?.["image-moderation"]) {
    const { attachments } = injectedObject.extensions["image-moderation"];
    for (const attachment of attachments) {
      if (!attachment.error) {
        const { unsafe } = attachment.data.verdict;
      }
    }
  }
}

​
Sentiment Analysis

{
  "@injected": {
    "extensions": {
      "sentiment-analysis": {
        "sentiment": "positive",
        "sentiment_score": {
          "positive": 95,

    }
  }
}

Virus & Malware Scanner

Scan uploaded files for malicious content using Scanii. Prerequisites Create a Scanii account and get your API Key and Secret. Response Format 
{
  "@injected": {
    "extensions": {
      "virus-malware-scanner": {
        "attachments": [{
          "data": {
            "url": "https://media.com/file.mp3",
            "verdict": {
              "scan_results": []
            }
          },
          "error": null
        }]

      "xss-filter": {

var metadata = message.getMetadata();
if (metadata != null) {
  var injectedObject = metadata["@injected"];
