+# Messaging Systems Integration
+
+This document provides a comprehensive guide for integrating with our messaging services, covering individual messaging, group messaging, WhatsApp integration, and thread management. It is intended for developers and product managers who need to understand and utilize our messaging APIs.
+
+## Introduction
+
+Our platform offers a variety of messaging endpoints to facilitate communication with users across different channels. This document aims to unify the documentation and provide practical integration examples to streamline the development process.
+

+
+## WhatsApp Integration
+
+This section details how to integrate with WhatsApp using our platform.
+
+### Endpoint
+
+`/v1/wa/whatsapp/incoming`
+
+### Description
+
+This endpoint receives incoming WhatsApp messages.  You will need to configure a webhook in your WhatsApp Business Account settings to point to this endpoint.
+
+### Webhook Setup Guide
+
+1.  **Configure Webhook URL:** In your WhatsApp Business Account settings, configure the webhook URL to point to `/v1/wa/whatsapp/incoming`.
+2.  **Verify Token:**  Set up a verification token in your WhatsApp Business Account settings and ensure your application can handle the verification request.
+3.  **Subscribe to Events:** Subscribe to the `messages` event to receive incoming message notifications.
+
+### Incoming Message Payload (Example)
+
+```json
+{
+  "object": "whatsapp_business_account",
+  "entry": [
+    {
+      "id": "whatsapp_business_account_id",
+      "time": 1666886666,
+      "changes": [
+        {
+          "value": {
+            "messaging_product": "whatsapp",
+            "metadata": {
+              "display_phone_number": "+15550000000",
+              "phone_number_id": "whatsapp_phone_number_id"
+            },
+            "contacts": [
+              {
+                "profile": {
+                  "name": "John Doe"
+                },
+                "wa_id": "+15551234567"
+              }
+            ],
+            "messages": [
+              {
+                "from": "+15551234567",

+        }
+      ]
+    }
+  ]
+}
+```
+
+### Responding to WhatsApp Messages

+## Integration Tutorials
+
+### Example: Sending a Welcome Message via WhatsApp
+
+This tutorial demonstrates how to send a welcome message to a new user via WhatsApp when they sign up for your service.
+
+1.  **User Signup:**  When a new user signs up, collect their phone number.
+2.  **Format Phone Number:** Ensure the phone number is in the correct format (e.g., +15551234567).
+3.  **Send Welcome Message:** Use the `/v1/messages/individual/{accountId}/send` endpoint to send a welcome message to the user's WhatsApp number.  You may need to use a WhatsApp template for this.
+
+```python
+import requests
+import json
+
+account_id = "your_account_id"
+recipient = "+15551234567"
+template_name = "welcome_message" # Replace with your template name
+template_language = "en_US"
+
+url = f"/v1/messages/individual/{account_id}/send"
+headers = {
+    "Content-Type": "application/json",
+    "Authorization": "Bearer YOUR_API_KEY" # Replace with your API key
+}
+
+data = {
+    "recipient": recipient,
+    "template": {
+        "name": template_name,
+        "language": template_language,
+        "components": [
+            {
+                "type": "body",
+                "parameters": [
+                    {
+                        "type": "text",
+                        "text": "User's Name" # Replace with the user's actual name
+                    }
+                ]
+            }
+        ]
+    }
+}
+
+response = requests.post(url, headers=headers, data=json.dumps(data))
+
+if response.status_code == 200:
+    print("Welcome message sent successfully!")
+    print(response.json())
+else:
+    print(f"Error sending welcome message: {response.status_code} - {response.text}")
+```
