The app handles 2 billion messages per day and is deeply embedded in Vietnamese daily life, revolutionizing communication for both individuals and businesses.\n\nZalo also offers an API platform for developers to build chatbots and automation tools directly within the app. This opens up powerful opportunities for creating AI-powered assistants, customer support bots, and real-time notification systems.\n\n### What is a Zalo Bot?\n\nA Zalo Bot is provided by Zalo that allows developers to build automated chat experiences using Zalo\u2019s API. These bots can receive and respond to user messages, making them ideal for use cases like news updates, customer service, appointment booking, and more.\n\nZalo Bots are now supported by n8n, enabling you to build intelligent workflows that connect Zalo with AI models, RSS feeds, databases, and other services.\n\nFollow these steps to create your bot and retrieve the token needed to authenticate API requests:\n\n### Step 1: Access Zalo Bot Creator\n- Open the Zalo app on your mobile device.\n- Use the search bar to find **\"Zalo Bot Creator\"**.\n- Tap to open the Official Account page.\n\n### Step 2: Create a New Bot\n- Tap the **\"Create Zalo Bot Account\"** button.\n- Fill in the required details:\n - Your bot\u2019s name must start with the prefix `\"Bot\"` (e.g., `Bot AI News Assistant`).\n - Add a description and profile image if needed.\n\n### Step 3: Receive Your Bot Token\n- Once the bot is successfully created, Zalo will send a message to your personal account.\n- This message contains your **Bot Token**\u2014a unique string used to authenticate API calls.\n- **Important:** Save this token securely. It will only be shown once.\n\n---\n\n## \u26a0\ufe0f Notes & Limitations\n- Zalo Bots currently **do not support voice messages, images, or file attachments**.\n- The bot name must follow Zalo\u2019s naming convention (starting with `\"Bot\"`).\n- You\u2019ll need the Bot Token to configure HTTP Request nodes in your n8n workflow.\n\n---\n\nOnce you have your Bot Token, you're ready to set up your webhook and start building your Zalo-powered automation with n8n!\n" }, "typeVersion": 1 } ], "connections": { "rss_read": { "ai_tool": [ [ { "node": "Summarize AI News", "type": "ai_tool", "index": 0 } ] ] }, "Send Zalo Message": { "main": [ [ { "node": "Send Zalo Message1", "type": "main", "index": 0 } ] ] }, "Summarize AI News": { "main": [ [ { "node": "Extract, Clean and Chunk Message Text", "type": "main", "index": 0 } ] ] }, "MongoDB Chat Memory": { "ai_memory": [ [ { "node": "Summarize AI News", "type": "ai_memory", "index": 0 } ] ] }, "Receive Zalo Webhook": { "main": [ [ { "node": "Summarize AI News", "type": "main", "index": 0 }, { "node": "Send Typing Action to Zalo", "type": "main", "index": 0 } ] ] }, "Gemini Language Model": { "ai_languageModel": [ [ { "node": "Summarize AI News", "type": "ai_languageModel", "index": 0 }, { "node": "Parse Structured AI Output", "type": "ai_languageModel", "index": 0 } ] ] }, "Parse Structured AI Output": { "ai_outputParser": [ [ { "node": "Summarize AI News", "type": "ai_outputParser", "index": 0 } ] ] }, "Extract, Clean and Chunk Message Text": { "main": [ [ { "node": "Send Zalo Message", "type": "main", "index": 0 } ] ] } } }
