Run a Giveaway with Twilio SMS

You are about to host a giveaway using Twilio SMS on a landing page. To start, create a URL that can create an auto-generated text message once clicked by a user on your landing page. You'll need a Twilio phone number and decide on the content of the pre-populated text message. Use an online URL encoder tool to encode the default message into a link, then add it to the tail end of a URL that will trigger the creation of an SMS message from the user's smartphone. Create a landing page for your giveaway using Milkshake or a self-hosted website, and design the page itself. You'll need to set up an HTTP POST request to respond to Twilio with TwiML instructions on how to handle the incoming message. The webhook will only be sent to the server once the SMS to your Twilio phone number is received, operating as a callback function or webhook. You'll add some useful if else logic to ensure that only users who send the scripted text will be eligible to enter the giveaway. After setting up the port and hosting the server, you can run the code in the command prompt and test your app by accessing the landing page from your smartphone.
