A contactless Secret Santa game built with Python, Flask and Twilio!

• A Twilio account. Sign up here
• ngrok
• Python >= 3.6

1. Clone this repo

git clone git@github.com:sjbitcode/secret-santa-twilio.git

2. Create a .env in the project root with cp .env.example .env
3. Copy your account sid, auth token, and Twilio phone number from your Twilio account to the .env file
4. Enter players in numbers.csv file. Check numbers.csv.example for phone number formatting

Note: If you're on a Twilio trial account, these numbers need to be verified with Twilio (see here)

1. From the project root, run make tunnel to create an ngrok tunnel on port 8000
2. Copy the Forwarding ngrok host to configure your Twilio SMS webhook, ex. http://998ad344.ngrok.io/sms (see here)
3. In another terminal, cd into the project root and run make app to run the Flask server on port 8000
4. Any player can start the game by texting start123 to the TWILIO_SENDING_NUMBER

Note: Check out this Medium article for help on getting the Twilio settings and configuring the webhook with ngrok

• TWILIO_ACCOUNT_SID - (required)
• TWILIO_AUTH_TOKEN - (required)
• TWILIO_SENDING_NUMBER - (required)
• DEBUG - Allows extended visibility into app logs (default False)
• DOLLAR_BUDGET - Secret Santa budget (default 30)

Note: The START_TRIGGER setting (start123) is not configurable and is case-sensitive!

The Secret Santa game is triggered by a phrase (start123) that anyone can send to the Twilio phone number.

Once the game has started, an SMS message is sent to everyone asking for their wishlist.

Confirmation SMS messages are sent to players as soon as they send their wishlist.

After all players enter their wishlist, the matches are calculated, and everyone receives a message with their Secret Santa's name, wishlist, and the budget amount.

The game is reset and can be played again.

Check out this flowchart for more detail.

The app makes use of Twilio's SMS webhook and REST API.

When an SMS message is sent to the Twilio number, Twilio sends a POST request to the webhook (see here).

The app logic will use Twilio's REST Client to send SMS messages to recipients (instead of using TwiML).
