Send text, audio, or image messages via WhatsApp\n2. Security filter validates authorized phone numbers\n3. Message router identifies content type\n4. Content is processed:\n - **Text**: Saved directly to Google Doc\n - **Audio**: Transcribed by Google Gemini AI, uploaded to Drive, transcription saved to Doc\n - **Images**: Uploaded to Drive, link saved to Doc\n5. Confirmation sent back via WhatsApp\n\n## Setup steps\n\n1. Configure WhatsApp Business API credentials\n2. Set up Google Service Account credentials\n3. Replace `YOURNUMBERPHONE(1/2/3)` in the security filter with authorized phone numbers (international format, no + sign)\n4. Replace `YOUR_GOOGLE_DOC_URL` in all Google Docs nodes\n5. Replace `YOUR_AUDIO_FOLDER_ID` and `YOUR_IMAGE_FOLDER_ID` in Google Drive nodes\n6. Replace `YOUR_WHATSAPP_PHONE_NUMBER_ID` in all confirmation nodes\n7. Configure Google Gemini API credentials for audio transcription\n\n**Test by sending a message to your WhatsApp Business number!**"
