https://partners.viber.com/account/create-bot-account

Developer Documentation

https://developers.viber.com/docs/

Node.JS Bot API => https://developers.viber.com/docs/api/nodejs-bot-api/

For Node.JS,

Create a file .env in main directory and add this below text

VIBER_ACCESS_TOKEN=Your Viber Access Token Add HERE
MONGODB_URI=Your Mongo DB Connection String Add Here
WEBHOOK_URL=Your Heroku URL like https://yourappname.herokuapp.com
PORT=3000

For local testing

Install ngrok globally with command

npm install -g ngrok

Clone project with

git clone https://github.com/YavorGrancharov/viber_bot.git

Install all dependencies with

npm install

Then, inside app.js file, replace this block of code:

app.listen(settings.port, async () => {
  try {
    console.log(`Application running on port: ${settings.port}`);
    bot.setWebhook(`${process.env.WEBHOOK_URL}/viber/webhook`);
  } catch (error) {
    console.log('Can not set webhook on following server.');
    console.error(error);
    process.exit(1);
  }
});

with this one:

app.listen(settings.port, async () => {
  try {
    const publicUrl = await getPublicUrl();
    console.log(`Application running on port: ${settings.port}`);
    console.log('publicUrl => ', publicUrl);
    bot.setWebhook(`${publicUrl}/viber/webhook`);
  } catch (error) {
    console.log('Can not set webhook on following server.');
    console.error(error);
    process.exit(1);
  }
});

and run project using commands npm run ngrok and npm run start on two separate terminals

You can see it running on localhost:3000
