Starter code to integrate sarufi with heyoo. This is a blueprint for deploying sarufi chabot on WhatsApp using WhatsApp Cloud API. In this blueprint, we shall set up a webhook to receive whatsapp messages. There are several ways you can set up a webhook. We shall be working on how to use ngrok and Replit in the deployment.

To get started using this blueprint for your sarufi bot, you will need TOKEN and TEST WHATSAPP NUMBER obtained from Facebook Developer Portal.

Here are steps to follow for you to get started:

• Go to your apps.
• create an app.
• Select Business >> Business.
• It will prompt you to enter basic app informations.
• It will ask you to add products to your app. Add Whatsapp.
• Right there you will see a your TOKEN and TEST WHATSAPP NUMBER and its phone_number_id.
• Lastly verify the number you will be using for testing on the To field.

Make sure you have ngrok installed in your working machine.

Have sarufi package installed on your machine before launching your whatsapp bot.

• Creae a project folder and virtual environment

  Lets Make a project folder named whatsapp-bot. Navigate into it to create virtual environment whatsapp-bot-env Activate the environment. Run the command to make the magic 🔥 happen.

  • For unix based systems [Linux and Mac]

    • Install virtual environment

      This step is optional as you may have python virtual environment already installed. If not, you can install it by running the command below.

      sudo apt install python3-venv

    • Create project folder and virtual environment

      mkdir whatsapp-bot
      cd whatsapp-bot
      python3 -m venv whatsapp-bot-env
      source  whatsapp-bot-env/bin/activate

  • For windows

    • Install virtual environment

      This step is optional as you may have python virtual environment already installed. If not, you can install it by running the command below.

      pip install virtualenv

    • Create project folder and virtual environment

      mkdir whatsapp-bot
      cd whatsapp-bot
      python -m venv whatsapp-bot-env
      whatsapp-bot-env\Scripts\activate.bat
      

• Create a file named .env

  In your working folder, create .env file to hold environment variables using your text editor.

  With the file created, add the following credentials. With whatsapp cloud api, instructions are at the top where as for sarufi, please read on how to get sarufi credentials.

   SARUFI_API_KEY  = Your API KEY
   SARUFI_BOT_ID   = Your Bot Id
   WHATSAPP_TOKEN  = Your Whatsapp token
   PHONE_NUMBER_ID = whatsapp phone number id
   VERIFY_TOKEN    = Your verify token

  Note: The verification token is a random string. You can just create a random string and use it as your verification token. It will be used to verify your webhook.

• Once you have environment variables set, you are ready to fire 🚀 your main.py in activated virtual envirnoment.

  1. Fire up your python script

  python3 main.py

  2. Start ngrok

  ngrok http 8000

  Note: keep the port number the same as used in main.py

• Finish up.

  After running the command, you will have to copy the url ngrok provides. The url looks like https://xxxxxxxxxxx.ngrok.io

  With the provided url, follow simple steps at Setting whatsapp webhook

  Open main.py, copy the VERIFY_TOKEN--> paste into verify token in your whatsapp cloud --> verify and save.

  We are heading a the best part of this journey. Just take time to subscribe to message topic. When done ,you are good to go... fire up your bot in whatsapp by sending text.

  🏁 When done with saving the token and url, go on to text your bot. Check out the sample below.

• Log into your Replit account.

  Fork the repo Whatsapp bot using sarufi API and heyoo into your account.

  Navigate to Tools--> Secrets to create environment variables. We have discussed on how to get whatsapp cloud api at the introduction part where as for sarufi view instructions here get sarufi credentials.
