- Get an api key from openai.com. Store it as OPENAI_API_KEY.
- Start the Flask app with
python3 app.py. - Create an ngrok account to make your app public. Run:
ngrok http 5002 --region us. It is important to choose the us location. Otherwise Meta will block your ngrok forwarding. - Add the ngrok url as a webhook to your WhatsApp Business App as explained here.

- Run:
python3 chatbot.py --new-number 49174xxxxxx", where you add the phone number you want to chat with here. This will send a hello world template message to your phone number. Now you can use this chat to chat with the bot. - If you want to restart the chat, just send "new chat" in the chat.
