In Display & Video 360, you can use various audience types to specify a subset of users to which ads are served. Through the Display & Video 360 API, you can retrieve available audiences and use them in resource targeting. You can also create certain types of audiences using first-party data.

This guide describes the different types of audiences available through the Display & Video 360 API and how to utilize them in your ad serving.


Before you start working with Display & Video 360 API services, you'll need to complete the following steps:

  1. Create and authorize an API project as outlined in our Getting Started guide.

  2. Ensure your Display & Video 360 user profile, identified by a user or service account email address, has Read & write user role permissions for the necessary advertiser or partner. Contact an existing Read & write user on your team to have these permissions enabled, if necessary.
