KISSmetrics API

The KISSmetrics API enables developers to add key metrics to their application quickly and easily. KISSmetrics is an analytics solution that provides a visual representation of a user's customer lifecycle. The API's most common functions include:

record events that take place within your product
set properties on a person without recording an event
set the identity of the current person using your product
associate one identity with another

The JavaScript API also has extra provisions for:

Automatically tracking identities using a variety of technologies
Automatically aliasing users anonymous identities with named identities you provide
Automatically tracking common web events (e.g. search engine traffic)
A/B Testing

A REST API is also available and an API key is required for use.
