Here's how to easily convert your KISSmetrics calls to Segment.io calls.

kissmetrics.js

/**
 * Identify
 * 
 * KISSmetrics' identify and set calls turn into an analytics.identify call.
 */
 
_kmq.push(['identify', 'USER_ID_HERE']);
_kmq.push(['set', {
  name  : 'Achilles',
  email : 'user@example.com'
}]);

analytics.identify('USER_ID_HERE', {
  name  : 'Achilles',
  email : 'user@example.com'
});


/**
 * Track
 * 
 * KISSmetrics' record call turns into an analytics.track call.
 */
 
_kmq.push(['record', 'Sign Up', {
  plan : 'Premium'
}]);

analytics.track('Sign Up', {
  plan : 'Premium'
});
