⚙️ Configuration

Environment Setup

Create a .env file in your project root:

# Nango Configuration for WhatsApp Business API
NANGO_CONNECTION_ID=your_nango_connection_id
NANGO_INTEGRATION_ID=whatsapp-business
NANGO_BASE_URL=https://api.nango.dev
NANGO_SECRET_KEY=your_nango_secret_key

# WhatsApp Business Configuration (Optional - can be set per call)
WHATSAPP_PHONE_NUMBER_ID=your_whatsapp_phone_number_id
WHATSAPP_BUSINESS_ACCOUNT_ID=your_whatsapp_business_account_id

Configuration Benefits

Environment Variables: Set your phone number ID and business account ID once in environment variables, then use them across all function calls without needing to specify them each time.

Flexibility: You can still override the environment variables by passing explicit values to individual function calls when needed.

Simplicity: For most use cases, you'll only need to set the environment variables once and then use simpler function calls:

# Simple - uses environment variables
send_text_message(to="+1234567890", message="Hello!")

# Explicit - overrides environment variables  
send_text_message(to="+1234567890", message="Hello!", phone_number_id="different_id")

Getting Nango Credentials

  1. Set up a Nango account
  2. Create a WhatsApp Business integration in Nango
  3. Set up your WhatsApp Business API connection
  4. Get your Nango connection ID and secret key

Getting WhatsApp Credentials

  1. Set up a WhatsApp Business Account
  2. Create a Meta Developer App
  3. Add WhatsApp Business API to your app
  4. Configure the integration in Nango with your WhatsApp credentials
