Etsy
We definitely encourage hackers to not only think about the Etsy buyer experience but to also consider the experience of our 800,000+ active sellers who are growing their creative, independent businesses from the ground up. One example might be an app that makes it easy for Etsy sellers to create and send thank you notes (with a holiday coupon offer!) to buyers via Sincerely.
Did you know the first item ever pinned on Pinterest was from Etsy? Did you know Etsy is the most popular source for Pins on the internets? Social curation is gaining steam and Etsy's right in the middle of it. How can you make discovering Etsy products more interesting and easy using the social curation that's already happening on Etsy and across the web?
If you owned a small business, wouldn't you want to know where your customers were coming from? CRM tools are hugely popular among Etsy sellers. Use the Etsy API to build maps that let sellers know where their best customers are from.

Using SendGrid's event API, you could monitor for when a user opens up a coupon that has already expired and automatically send them a new one.
If you're a heavy online shopper, it can be hard to manage all the receipts that accumulate in your inbox during a month.
Using SendGrid's parse API, you could aggregate all of a user's purchases during a month and send them a summary. This could be something like a Trip.it for receipts.
Using SendGrid's parse API, analyze a user's purchases and send them email recommendations of other things that they could buy.

Shopify
Shopify is a hosted eCommerce platform powering over 30,000 online stores for the likes of Penny Arcade, Epic Meal Time, Stack Exchange, and Wikipedia. Shopify Apps are web applications that talk to Shopify over our RESTful API that end up making our merchants happy in one way or another. You can write them in any language but we have great adapters for Ruby, Python, PHP, Java, and .NET.
The Shopify API lets your app do almost anything a merchant can with their own store including run sales; gather + analyze customer, sales data; add front-end functionality for customers to use; and post articles or full pages of content.
We've also got Webhooks that allow you to be notified in real time whenever something happens on a shop. Here are some useful links to get you on your way: Get started by signing up for our Partners program: partners.shopify.com; Familiarize yourself with the API: api.shopify.com; Read up on our App Fund and
