User identification

The different modes of identifying users with walker.js
You can add more information about the user by using three different levels of identification:
  1. 1.
    ID: e.g. user id from your CRM system
  2. 2.
    Device: e.g. a random value stored on a cookie
  3. 3.
    Hash: e.g. a session id
import { elb } from '@elbwalker/walker.js';
​
elb("walker user", {
id: "userid", // optional
device: "deviceid", // optional
hash: "sessionid" // optional
});
This example will lead to the following event:
{
"event": "entity action",
"user": {
"id": "userid",
"device": "deviceid",
"hash": "hashid"
}
// other properties omitted
}
We highly recommend only using fully anonymized & arbitrary ids by default and checking your options with persistent user IDs with your data protection officer.
