Audience Segment Endpoints

Introduction

Audience Segments represent groups of users, defined either explicitly through Contact Lists provided externally or by User Events intent behaviors automatically collected through our retailers integrations.

Multiple Audience Segments can be combined together using logical Algebra Nodes to defined the desired target audience for your campaigns.

🚧
Note on Audience Computation
Audience updates are processed daily at 0h UTC and 12h UTC and can take around 5 hours to reflect on a live campaign. This is important for audiences that are frequently updated as changes should be ready for processing prior to these two times.

Note on Audience Computation
Audience updates are processed daily at 0h UTC and 12h UTC and can take around 5 hours to reflect on a live campaign. This is important for audiences that are frequently updated as changes should be ready for processing prior to these two times.
