Our REST API is the main channel for getting data out of Kissmetrics. We have endpoints for account-level data (like the names of your events, properties, report names, etc), but more importantly, we offer a slew of ad-hoc query options for you to query your product data that is stored in your Kissmetrics instance.
The REST API is in beta!
Please take note that the REST API is still under heavy development and subject to regular changes. These changes could result in breaking changes for developers. We will try our best to notify the community of any breaking changes and help ensure a smooth transition if necessary.
