"content": "How to obtain Whatsapp API?\n\n\n### ✅ Prerequisites\nBefore you begin, make sure you have:\n- A **Meta Business Account**\n- A **Facebook Developer Account**\n- A **Verified Business**\n- A **Phone Number** to link to WhatsApp\n- Access to **Meta's Graph API Explorer** or **Meta for Developers portal**\n\n---\n\n### 🪜 STEP 1: Create a Meta App\n\n1. Go to [{{ $env.WEBHOOK_URL }}]({{ $env.WEBHOOK_URL }}\n2. Click **“Create App”**\n3. Choose **\"Business\"** as the app type, then click **Next**\n4. Give your app a name and enter a contact email\n5. Choose your Business Account (or create one)\n6. Click **Create App**\n\n---\n\n### 🪜 STEP 2: Add WhatsApp Product\n\n1. In your app dashboard, scroll down to **\"Add a Product\"**\n2. Find **\"WhatsApp\"** and click **“Set Up”**\n3. Link your **Business Manager Account**\n\n---\n\n### 🪜 STEP 3: Create a WhatsApp Business Account (if needed)\n\n1. If you haven’t already, go to [{{ $env.WEBHOOK_URL }}]({{ $env.WEBHOOK_URL }}\n2. Click **“Create Account”**, and complete your business information\n3. Go to **Business Settings > Accounts > WhatsApp Accounts**\n4. Add a **Phone Number** (you'll receive a verification code)\n\n---\n\n### 🪜 STEP 4: Generate a Temporary Access Token (for development)\n\n1. In the **App Dashboard**, go to **WhatsApp > Getting Started**\n2. Choose your test phone number\n3. Copy the **temporary access token** (valid for 24 hours)\n4. Copy the **Phone Number ID** and **WhatsApp Business Account ID**\n\n✅ Save these 3 values:\n- **Access Token**\n- **Phone Number ID**\n- **WABA ID**\n\n📝 Tip: For production, you will later need to create a **permanent token** (see step 7).\n\n---\n\n### 🪜 STEP 5: Set Up a Webhook URL (n8n)\n\n1. In n8n, set up a **Webhook node** (or use the `WhatsApp Trigger` node)\n2. Copy the webhook URL\n3. In the Meta Developer Dashboard:\n - Go to **WhatsApp > Configuration**\n - Click **“Edit Callback URL”**\n - Paste your n8n webhook URL and add a random **verify token**\n4. In n8n, configure your webhook to respond to the verification request\n\n---\n\n### 🪜 STEP 6: Subscribe to Webhook Fields\n\n1. Still under **WhatsApp > Configuration**, click **\"Manage Subscriptions\"**\n2. Enable:\n - `messages`\n - `message_status`\n - (Optionally `message_template_status_update`)\n\n---\n\n### 🪜 STEP 7: (Optional but recommended) Generate a Permanent Token\n\n1. Go to [{{ $env.WEBHOOK_URL }}]({{ $env.WEBHOOK_URL }}\n2. Select your app\n3. Click **Get Token > System User Token**\n4. Select the permissions:\n - `whatsapp_business_management`\n - `whatsapp_business_messaging`\n - `business_management`\n5. Click **Generate Token**\n6. Copy and securely store this token\n\n---\n\n### 🪜 STEP 8: Configure Credentials in n8n\n\n1. Go to **n8n > Settings > Credentials**\n2. Create new credentials of type **HTTP Header Auth**\n - **Name:** WhatsApp\n - **Header Name:** `Authorization`\n - **Value:** `Bearer <your_access_token>`\n3. Save\n\nThen, in your workflows:\n- Use the HTTP Request node or WhatsApp node\n- Set the `phone_number_id` in the node parameters\n- Connect it to your WhatsApp credential\n\n---\n\n### 🧪 STEP 9: Test the Connection\n\n1. Use a WhatsApp number to send a message to your business phone\n2. Your n8n workflow should be triggered\n3. You can now send and receive messages programmatically 🎉\n"
