Our Send Anywhere team is thrilled to announce the first Hackathon with the recently optimized API of our software. We take great pride in providing an unlimited file sharing service but we do not want to stop here. We wish to go a step further by letting skilled developers to give birth to innovative solutions with the core competencies of our service.

Request your Send Anywhere API Key and visit the documentation page to get all the necessary documents and resources you need to build your app.

Hosting the Hackathon will give us an opportunity to see a fresh outlook of what could possibly done on Send Anywhere. Just to mention a few, we are trying to find new solutions how our API could be used in widely used messenging apps, media players, media editor softwares and etc. Send Anywhere sticks out among its competitors due to the following reasons:

-It is compatible in multiple platforms

-There is no limit in file size of file type 

-The digital contents transferred through Send Anywhere are secured because the 6-digit key disppears once its downloaded from the receiving device or the 10 minute limit passes. 

-No sign-up or log-in is required 

We take a lot of pride on the service we provide and thus we believe that with Send Anywhere's API even more creative and innovative solutions can come to light. 

Make sure to tell you friends about the Hackathon and follow us @Send_Anywhere to stay up to date for some new features in the coming weeks.
