I searched the page for any kind of technical information, and found a very discrete, almost invisible link to the "API documentation" in the footer of the page.
The link leads to a github README, that informs me I have to post JSON to a certain URL.
Just by chance I checked out their other github repos and noticed that they already have client libraries for iOS, ruby, node and Android.
I've only checked out the iOS version, but it has a pretty nice interface, and would take literally minutes to add to my project. It even posts the report automatically on fatal errors.
Why was this not a prominent feature box on the front page?
I understand they market it to project managers an the like, but it seems useful to try to get the developers on board from the beginning. Often, it will be the job of the developer to find a suitable solution anyway.
