  5. Enter the “API Key” in the Lou destination settings in Segment.


If you aren’t familiar with the Segment Spec, take a look at the Identify method documentation to learn about what it does. An example call would look like:

analytics.identify('userId123', {
  company: 'Company A',
  permissions: 'admin',

Segment sends traits in Identify calls to Lou as properties that can be used in Custom Segments to group users into different audiences.

Lou does not accept any personally identifiable information (PII) fields from Identify calls. These fields are automatically filtered out so they do not reach Lou’s servers. For a full list of PII fields that Lou removes from Identify calls, see Lou’s Segment integration documentation.


If you aren’t familiar with the Segment Spec, take a look at the Track method documentation to learn about what it does. An example call would look like:

analytics.track('Login Button Clicked')

Segment sends Track calls to Lou as Events that can be used to define Goals.


You can send computed traits and audiences generated using Engage to this destination as a user property. To learn more about Engage, schedule a demo.

For user-property destinations, an identify call is sent to the destination for each user being added and removed. The property name is the snake_cased version of the audience name, with a true/false value to indicate membership. For example, when a user first completes an order in the last 30 days, Engage sends an Identify call with the property order_completed_last_30days: true. When the user no longer satisfies this condition (for example, it’s been more than 30 days since their last order), Engage sets that value to false.

When you first create an audience, Engage sends an Identify call for every user in that audience. Later audience syncs only send updates for users whose membership has changed since the last sync.

Real-time to batch destination sync frequency

Real-time audience syncs to Lou may take six or more hours for the initial sync to complete. Upon completion, a sync frequency of two to three hours is expected.


Segment lets you change these destination settings from the Segment app without having to touch any code.
