The HelloSign “Go Paperless” Hackathon is calling all developers to rethink legacy print, sign, and scan approval processes with the HelloSign eSignature API

It’s 2022 and much of the world still depends on pen and paper signatures to do business

Use your creativity to identify opportunities where having eSign capabilities can create value for your users. Our SDKs—available across Python, Ruby, PHP, Java, NodeJS, and C#.NET—will help get your projects up and running in a flash. This hackathon is open to individuals and teams alike

What is HelloSign?

HelloSign, a Dropbox company, is the simple and secure way to sign agreements online. Our API makes it easy to get started and integrate eSignatures into your application in just a few hours.

We know firsthand that eSignature has the ability to significantly improve efficiency, sustainability, and productivity for businesses and customers alike. That’s why we focus on creating tools and a best-in-class developer experience that can help us scale that capability as broadly as possible


What to build?

Think big ! Add the HelloSign API in a new (or existing) app, leveraging our new OpenAPI-powered SDKs that recently launched to beta. Put yourself in the shoes of users in a situation where they have to sign something, and reimagine that experience to make it a more meaningful process for your users 

What to Submit 
  • Answer all submission questions completely
  • Demo video – use of Dropbox Capture encouraged 
    • Around 5 minutes (+/- ~10 seconds)
    • Clearly explains features and functionality of your app
  • Demonstrate usage of HelloSign beta SDKs
