Aliasing Users

Method URL:

• http://trk.kissmetrics.com/a
• https://trk.kissmetrics.com/a

Parameters (GET)

Parameters	Format	Necessary?	Description
_k	string	Yes	Your API key
_p	255 char string	Yes	One of the person’s identities
_n	255 char string	Yes	Another of the person’s identities

Example

http://trk.kissmetrics.com/a?_k=api-key&_p=bob&_n=bob%40bob.com

This tells us to treat bob and bob@bob.com as the same person. If you log events or properties to either ID, they all refer back to the same one person. (bob@bob.com is passed as bob%40bob.com because the @ needs to be URL-encoded.)
You most frequently use this to connect a person’s ID when they are anonymous with the same person’s ID when they are known (that is, to connect a randomly generated ID with their username, an email address, Facebook ID, whatever).
It’s OK to call this more than once with the same pair of identities. It’s also OK if a person has more than one alias.
