Audiences Endpoints

Introduction

Audiences give the ability to advertisers to define subsets of retailer visitors to be targeted in their campaigns.

Audiences are built of one or multiple audience segments that can be combined using logical Algebra Nodes to define target campaigns' audiences.

⚠️
The corresponding App should have the "Audiences Manage" permission enabled for all endpoints on this page.

🚧
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.

📘
The endpoints and functionalities covered in this page refers to features available exclusively in Preview for now, which doesn't mean that they are the only ones available for this domain/scope.
For more complete information about our API capabilities, check the Stable version in Welcome to Criteo Retail Media API

📘
Partial Approvals
Bulk operations (create, update, delete) use a partial approval model. Even if some items in the request fail, the response will return 200 OK. Any failed items will be listed in the error section of the response with an error code and details.
Examples of possible error codes:

audience-not-found → Audience is not found.

name-must-be-unique → Audience name must be unique.

name-must-not-be-empty → Audience name property must not be empty.

This list is not exhaustive. Additional warnings may be returned depending on the request context.
