​
Overview

Typing indicators and read receipts provide real-time feedback to users, making conversations feel more natural and interactive. These features help users understand when you’re responding and confirm when their messages have been seen.

​
Key Features

  • Typing Indicators: Show when you’re composing a response
  • Read Receipts: Mark messages as read to acknowledge receipt
  • Smart Duration: Customizable typing indicator duration (up to 25 seconds)
  • Message Context: Link typing indicators to specific messages
  • Automatic Management: Built-in timeout and state management

​
How It Works

​
Typing Indicators

When you send a typing indicator, the user sees the familiar “typing…” animation in their chat, similar to regular WhatsApp conversations. This provides immediate feedback that their message was received and you’re preparing a response.

​
Read Receipts

Read receipts show blue checkmarks next to messages, indicating they’ve been read. This helps users know their messages were seen, even if you don’t respond immediately. User’s View: 
[Their message] ✓✓ (delivered)
[Their message] ✓✓ (read - blue checkmarks)
[Typing indicator] You are typing...

​
Types and Interfaces

// Enum additions
export enum WhatsAppMessageType {
  // ... existing types
  TYPING_INDICATOR = 'typing_indicator',
  READ_RECEIPT = 'read_receipt',
}

// Typing indicator message structure
export interface TypingIndicatorMessage {
  messaging_product: 'whatsapp';
  recipient_type?: 'individual';
  to: string;
  message_id?: string;
  status?: 'read';
  typing_indicator: {
    type: 'text';
  };
}

// Read receipt message structure
export interface ReadReceiptMessage {
  messaging_product: 'whatsapp';
  status: 'read';
  message_id: string;
}

// Response interface
export interface TypingIndicatorResponse {
  success: boolean;
  messageId?: string;
  error?: string;
}

Methods

​
Typing Indicators

// Basic typing indicator (25 seconds default)
async sendTypingIndicator(to: string, messageId?: string): Promise<TypingIndicatorResponse>

// Typing indicator with custom duration
async sendTypingIndicatorWithDuration(
  to: string,
  duration: number = 25000,
  messageId?: string
): Promise<TypingIndicatorResponse>

​
Read Receipts

// Mark specific message as read
async markMessageAsRead(messageId: string): Promise<TypingIndicatorResponse>

​
Usage Examples

​
Basic Typing Indicators

import { WhatsAppClient } from 'whatsapp-client-sdk';

const client = new WhatsAppClient(accessToken, phoneNumberId);

// Simple typing indicator
await client.sendTypingIndicator('+1234567890');

// Typing indicator linked to specific message
await client.sendTypingIndicator('+1234567890', messageId);

// Custom duration (15 seconds)
await client.sendTypingIndicatorWithDuration('+1234567890', 15000);

// Custom duration with message context
await client.sendTypingIndicatorWithDuration('+1234567890', 20000, messageId);

​
Read Receipts

// Mark a message as read
await client.markMessageAsRead('wamid.HBgLMTY1MDM4Nzk0MzkVAgARGBJDQjZCMzlEQUE4OTJCMTE4RTUA');

​
Intelligent Conversation Flow

async function handleUserMessage(message) {
  // 1. Immediately mark as read
  await client.markMessageAsRead(message.id);

  // 2. Show typing indicator while processing
  await client.sendTypingIndicator(message.from, message.id);

  // 3. Simulate processing time
  await new Promise(resolve => setTimeout(resolve, 3000));

  // 4. Send response
  await client.sendText(message.from, 'Thanks for your message! How can I help you?');
}

​
Webhook Integration

​
Smart Response System

const webhookProcessor = client.createWebhookProcessor({
  onTextMessage: async (message) => {
    // Mark as read immediately
    await client.markMessageAsRead(message.id);

    const query = message.text.toLowerCase();

    if (query.includes('help') || query.includes('support')) {
      // Show typing for support queries
      await client.sendTypingIndicatorWithDuration(message.from, 10000, message.id);

      // Process support request
      const supportResponse = await processSupportQuery(query);

      await client.sendText(message.from, supportResponse);
    }

    else if (query.includes('order') || query.includes('status')) {
      // Longer typing for order lookups
      await client.sendTypingIndicatorWithDuration(message.from, 20000, message.id);

      // Look up order information
      const orderInfo = await lookupOrder(query);

      await client.sendText(message.from, orderInfo);
    }

    else {
      // Quick acknowledgment
      await client.sendTypingIndicator(message.from, message.id);

      await new Promise(resolve => setTimeout(resolve, 2000));

      await client.sendText(message.from, 'Got it! Let me help you with that.');
    }
  },

  onImageMessage: async (message) => {
    await client.markMessageAsRead(message.id);
    await client.sendTypingIndicator(message.from, message.id);

    // Process image
    await new Promise(resolve => setTimeout(resolve, 5000));

    await client.sendText(message.from, 'Thanks for sharing the image!');
  },

  onButtonReply: async (message) => {
    await client.markMessageAsRead(message.id);

    // Quick response for button clicks
    await client.sendTypingIndicatorWithDuration(message.from, 5000);

    const response = await processButtonAction(message.button.id);
    await client.sendText(message.from, response);
  }
});

Advanced Conversation Management

class ConversationManager {
  private activeTyping = new Map();

  async startTypingSession(userPhone, messageId, expectedDuration) {
    // Prevent multiple typing indicators
    if (this.activeTyping.has(userPhone)) {
      return;
    }

    this.activeTyping.set(userPhone, {
      messageId,
      startTime: Date.now(),
      duration: expectedDuration
    });

    await client.sendTypingIndicatorWithDuration(userPhone, expectedDuration, messageId);

    // Auto-cleanup
    setTimeout(() => {
      this.activeTyping.delete(userPhone);
    }, expectedDuration);
  }

  async handleComplexQuery(message) {
    await client.markMessageAsRead(message.id);

    const complexity = this.analyzeQueryComplexity(message.text);

    // Adjust typing duration based on complexity
    const duration = complexity === 'simple' ? 5000 :
                    complexity === 'medium' ? 15000 : 25000;

    await this.startTypingSession(message.from, message.id, duration);

    // Process based on complexity
    const response = await this.processQuery(message.text, complexity);

    await client.sendText(message.from, response);
  }

  analyzeQueryComplexity(text) {
    const wordCount = text.split(' ').length;
    const hasMultipleQuestions = (text.match(/\?/g) || []).length > 1;
    const hasComplexTerms = /order|refund|technical|problem|issue/.test(text.toLowerCase());

    if (wordCount > 20 || hasMultipleQuestions || hasComplexTerms) {
      return 'complex';
    } else if (wordCount > 10) {
      return 'medium';
    }
    return 'simple';
  }
}

Advanced Use Cases

​
Customer Service Bot

class CustomerServiceBot {
  async handleCustomerMessage(message) {
    // Always acknowledge receipt
    await client.markMessageAsRead(message.id);

  }
}

​
Progressive Response System

class ProgressiveResponder {
  async handleLongProcess(message, processFunction) {
    // Initial acknowledgment
    await client.markMessageAsRead(message.id);
    await client.sendTypingIndicator(message.from, message.id);

    await client.sendText(message.from, 'Processing your request...');

    // Show continued activity
    const processSteps = [
      'Analyzing your request...',
      'Retrieving information...',
      'Preparing response...'
    ];

    for (let i = 0; i < processSteps.length; i++) {
      await client.sendTypingIndicatorWithDuration(message.from, 8000);

      const stepResponse = await client.sendText(message.from, processSteps[i]);

      // React to our own message to show progress
      await client.reactWithCheck(message.from, stepResponse.messages[0].id);

      await new Promise(resolve => setTimeout(resolve, 3000));
    }

    // Final typing before result
    await client.sendTypingIndicatorWithDuration(message.from, 10000);

    const result = await processFunction(message);

    await client.sendText(message.from, result);
  }
}

Smart Retry Logic

class SmartTypingManager {
  async safeTypingIndicator(userPhone, messageId, duration = 25000) {
    try {
      const response = await client.sendTypingIndicatorWithDuration(
        userPhone,
        duration,
        messageId
      );

      if (!response.success) {
        console.log('Typing indicator failed:', response.error);
        // Continue without typing indicator
        return false;
      }

      return true;
    } catch (error) {
      console.error('Typing indicator error:', error);
      // Don't let typing failures break the conversation
      return false;
    }
  }

  async safeReadReceipt(messageId) {
    try {
      const response = await client.markMessageAsRead(messageId);

      if (!response.success) {
        console.log('Read receipt failed:', response.error);
      }

      return response.success;
    } catch (error) {
      console.error('Read receipt error:', error);
      return false;
    }
  }

  async smartConversationFlow(message, responseFunction) {
    // Try to mark as read (non-blocking)
    await this.safeReadReceipt(message.id);

    // Estimate response time
    const estimatedTime = await this.estimateResponseTime(message);

    // Show typing if we have a good estimate
    if (estimatedTime > 2000) {
      await this.safeTypingIndicator(
        message.from,
        message.id,
        Math.min(estimatedTime, 25000)
      );
    }

    // Generate response
    const response = await responseFunction(message);

    // Send response
    await client.sendText(message.from, response);
  }
}

​
Message Structure

​
Typing Indicator Message

{
  messaging_product: 'whatsapp',
  recipient_type: 'individual',
  to: '+1234567890',
  message_id: 'wamid.HBgLMTY1MDM4Nzk0MzkVAgARGBJDQjZCMzlEQUE4OTJCMTE4RTUA', // Optional
  typing_indicator: {
    type: 'text'
  }
}

​
Read Receipt Message

{
  messaging_product: 'whatsapp',
  status: 'read',
  message_id: 'wamid.HBgLMTY1MDM4Nzk0MzkVAgARGBJDQjZCMzlEQUE4OTJCMTE4RTUA'
}

​
Best Practices

​
1. Timing and Duration

// ✅ Good: Match typing duration to actual processing time
const processingTime = estimateProcessingTime(query);
await client.sendTypingIndicatorWithDuration(userPhone, processingTime, messageId);

// ✅ Good: Quick acknowledgment for simple queries
await client.sendTypingIndicator(userPhone, messageId); // 25s default
await processSimpleQuery();

// ❌ Avoid: Overly long typing for simple responses
// ❌ Avoid: No typing indicator for complex processes

​
2. Read Receipt Management

// ✅ Good: Mark as read immediately upon processing
webhookProcessor.onTextMessage = async (message) => {
  await client.markMessageAsRead(message.id); // First thing
  await processMessage(message);
};

// ✅ Good: Mark as read even if auto-responding
if (isAutoResponse(message)) {
  await client.markMessageAsRead(message.id);
  await sendAutoResponse(message);
}

// ❌ Avoid: Forgetting to mark important messages as read
// ❌ Avoid: Marking messages as read without processing them

​
3. User Experience Flow

// ✅ Good: Complete interaction flow
async function completeInteractionFlow(message) {
  // 1. Acknowledge receipt
  await client.markMessageAsRead(message.id);

  // 2. Show activity
  await client.sendTypingIndicator(message.from, message.id);

  // 3. Process
  const response = await processMessage(message);

  // 4. Respond
  await client.sendText(message.from, response);

  // 5. Optional: React to show satisfaction
  if (wasSuccessful(response)) {
    await client.reactWithCheck(message.from, message.id);
  }
}

​
4. Error Handling

async function robustTypingFlow(message) {
  try {
    await client.markMessageAsRead(message.id);
  } catch (error) {
    console.log('Read receipt failed, continuing...');
  }

  try {
    await client.sendTypingIndicator(message.from, message.id);
  } catch (error) {
    console.log('Typing indicator failed, continuing...');
  }

  // Always try to send the actual response
  try {
    const response = await processMessage(message);
    await client.sendText(message.from, response);
  } catch (error) {
    await client.sendText(
      message.from,
      'Sorry, I encountered an error processing your request. Please try again.'
    );
  }
}

​
Limitations

  • Duration Limit: Typing indicators can last maximum 25 seconds
  • One at a Time: Only one typing indicator per conversation at a time
  • Message Age: Can only mark messages as read within 30 days
  • Rate Limits: These actions count toward your messaging rate limits
  • No Persistence: Typing indicators don’t persist across app restarts

​
Configuration Tips

​
Response Time Optimization

class ResponseTimeOptimizer {
  constructor() {
    this.averageResponseTimes = new Map();
  }

  async optimizeTypingDuration(messageType, userPhone) {
    const userHistory = this.averageResponseTimes.get(userPhone) || {};
    const avgTime = userHistory[messageType] || this.getDefaultTime(messageType);

    // Add 20% buffer but cap at 25 seconds
    return Math.min(avgTime * 1.2, 25000);
  }

  getDefaultTime(messageType) {
    const defaults = {
      'simple_text': 3000,
      'complex_query': 15000,
      'order_lookup': 20000,
      'technical_support': 25000
    };

    return defaults[messageType] || 10000;
  }

  recordResponseTime(messageType, userPhone, actualTime) {
    if (!this.averageResponseTimes.has(userPhone)) {
      this.averageResponseTimes.set(userPhone, {});
    }

    const userTimes = this.averageResponseTimes.get(userPhone);
    const currentAvg = userTimes[messageType] || actualTime;

    // Rolling average
    userTimes[messageType] = (currentAvg * 0.8) + (actualTime * 0.2);
  }
}
