Square’s latest hackathon — Build What’s POS-sible — is now live! While Square is well known for its payments and point-of-sale solutions, there’s so much more. Today, they have APIs that span across every aspect of a business, including customer solutions such as Customers, Invoices, Labor, Loyalty, Team Management, and Gift Cards.

Build your app using at least one of the customer point-of-sale APIs between October 5, 9:00 a.m. Pacific Time to November 22, 1:59 p.m. Pacific Time. Submit before their deadline!

With the Build What’s POS-sible hackathon, developers can utilize one or more of our customer point-of-sale APIs to build useful tools that help sellers scale and grow their business. Plus, you’re also free to use a wide array of the APIs available within the Square developer platform to build more robust apps and integrations–as long as you’re building with at least one of our customer point-of-sale APIs to be eligible for the hackathon. Build what’s possible for a chance to claim your part of $100k in prizes–including a $20k grand prize.

Mention @squaredev and let them know what you’re working on using the hashtag #BuildWhatsPOSsible. Good luck!
