WhatsApp Trivia Game

This is a project that I worked on during Vonage OneHack 2020. It's a simple trivia game that downloads questions from the Open Trivia Database API and presents them to the user. It uses the Vonage Sandbox WhatsApp account.

It could do with some work - the error checking isn't fit for purpose and you might want to implement categories, difficulty levels, etc. See here for details.

To run it

  1. Clone this repo to your local machine.

  2. In your working directory, create a Nexmo application:

    nexmo app:create "WA Trivia App" --capabilities=messages --messages-inbound-url=https://example.com/webhooks/inbound-message --messages-status-url=https://example.com/webhooks/message-status --keyfile=private.key

    This downloads a private.key file containing your authentication details and a .nexmo-app file that contains those together with your APPLICATION_ID.

  3. Copy example.env to .env and fill in the blanks. The FROM_NUMBER is your Nexmo virtual number. The TO_NUMBER is the number that identifies your WhatsApp account. The pre-filled WHATSAPP_NUMBER is for the Sandbox account. The APPLICATION_ID is the one you generated in the preceding step.

  4. Run ngrok to get some temporary tunnel URLs:

    ngrok http 5000

  5. Visit the Messages Sandbox and follow the instructions to whitelist your TO_NUMBER.

  6. Enter the following URLs in the "Webhooks" section:

    • Inbound: NGROK_URL/webhooks/inbound
    • Status: NGROK_URL/webhooks/status

  7. With ngrok running, launch your app:

    npm start

  8. Send the word quiz to the WhatsApp Sandbox account and the quiz should start!
