2. Download the ngrok agent.

4. Follow the instructions to authenticate your ngrok agent. You only have to do this once.
5. On the left menu, expand Cloud Edge and then click Domains.

How to Run

Run locally

Clone the repository

https://github.com/H4K3R13/KrishiSahay.git

Change the directory

cd KrishiSahay

Setup virtual env

python3 -m python3 -m venv venv
source venv/bin/activate

Install the modules

pip3 install -r requirements.txt

Change directory to bots

cd python-whatsapp-bot

Run flask app

flask --app run.py --debug run

Run ngrok

Once your app is running successfully on localhost, let's get it on the internet securely using ngrok!

ngrok http 8000 --domain your-domain.ngrok-free.app

8. ngrok will display a URL where your localhost application is exposed to the internet (copy this URL for use with Meta).

Configure of Webhooks

In the Meta App Dashboard, go to WhatsApp > Configuration, then click the Edit button.

1. In the Edit webhook's callback URL popup, enter the URL provided by the ngrok agent to expose your application to the internet in the Callback URL field, with /webhook at the end (i.e. https://myexample.ngrok-free.app/webhook).
2. Enter a verification token. This string is set up by you when you create your webhook endpoint. You can pick any string you like. Make sure to update this in your VERIFY_TOKEN environment variable.
