Answer a question

I had cloned these file as per facebook instructions

And then Step 1: Create a biz Directory for the Setup Scripts

mkdir ~/biz; cd ~/biz;

Step 2: Get the WhatsApp Business API Client Configuration Files

   db.env

docker-compose.yml

multiconnect-compose.yml

Step 3: Set the WA_API_VERSION Environment Variable

export WA_API_VERSION=2.31.5

Step 4: Start the WhatsApp Business API Client

docker-compose up -d

The resulting output should look like the following:

Recreating whatsbusinessapi_db_1 ... done
Creating whatsbusinessapi_wacore_1 ... done
Creating whatsbusinessapi_waweb_1  ... done

Step 5: Verify Containers Are Running

docker-compose ps

output :

          Name                         Command               State                     Ports                   
---------------------------------------------------------------------------------------------------------------
whatsbusinessapi_db_1       docker-entrypoint.sh -p 54 ...   Up      5000/tcp, 5432/tcp, 0.0.0.0:5000->6000/tcp
whatsbusinessapi_wacore_1   /opt/whatsapp/bin/wait_on_ ...   Up      6250/tcp, 6251/tcp, 6252/tcp, 6253/tcp    
whatsbusinessapi_waweb_1    /opt/whatsapp/bin/wait_on_ ...   Up      0.0.0.0:9090->443/tcp

By default, the Webapp container will be running on port 9090 (https://localhost:9090) as per facebook but when i tried https://localhost:9090

So anyone have idea please.

The WhatsApp Web Business Tool is deprecated since v2.29.1 You can only interact with your instance via REST API. You can leverage our Postman collection for this https://github.com/fbsamples/WhatsApp-Business-API-Postman-Collection

Sounds like you are ready to proceed with Step 6
