Build a connected e-commerce app

What could you create if you had 30 minutes to plan and 4 hours to build? Bree Hall, Anthony D. Mays, Ximena Vila Ferral, and Robbie Wagner took on the Web Dev Challenge to find out.

The Challenge

Come up with ways to connect people’s behavior to e-commerce incentives.

Creating brand loyalty is everything to an e-commerce store. Our friends at Blvck Spades have a great product, and they need help coming up with ways to incentivize users to interact with their brand.

Your challenge is to build software that connects a user’s activity to incentives. Beyond an e-commerce store, many businesses might have an app, partnerships, or physical locations or events — our job is to connect a user’s activity in these other places to incentives in the e-commerce store using the Mailchimp users as the source of truth.

For example, something like “play 10 rounds of our game and get 10% off your order in the store”, or “show up to a local meetup and earn an exclusive, limited edition t-shirt”.

IMPORTANT: You do not have to build the full e-commerce store part of this! In fact, it’s probably not possible given the time constraint. Instead, focus on building the fun interaction thing and making the note in Mailchimp that the user has done the thing that earns the incentive.

The Tools

Apps must use Intuit Mailchimp, an email and marketing automation platform. Specifically, devs are encouraged to use the Members API for managing a given user's accomplishments, coupon codes, or other details.
