# Audiences are lists of users. Use audiences to direct ads towards users or try
to avoid users.

In the Display \& Video 360 API, audiences use different resource types. Target all of them
under the targeting type `TARGETING_TYPE_AUDIENCE_GROUP`. Read about how to
target audiences in the [audience list targeting guide](https://developers.google.com/display-video/api/guides/concepts/targeting/audience-list).

## Audience types

In the Display \& Video 360 API, the audience source determines the resource type.

### Google audiences

Google Audiences are created and managed by Google. Users are grouped by
affinity, life event, or purchase intent.

These are [`GoogleAudience`](https://developers.google.com/display-video/api/reference/rest/current/googleAudiences#GoogleAudience) resources in the API. Get these
audiences using the `googleAudiences` service. These audiences can't be created
or updated with the API.

> [!CAUTION]
> **Caution:** [Extended Demographic audiences](https://developers.google.com/display-video/api/reference/rest/current/googleAudiences#GoogleAudienceType.ENUM_VALUES.GOOGLE_AUDIENCE_TYPE_EXTENDED_DEMOGRAPHIC) aren't fully supported by the Display \& Video 360 API. They can't be added or retrieved in assigned targeting.

### First-party and partner audiences

> [!IMPORTANT]
> **Important:** [Upgrade your Customer Match workflows to the Data Manager
> API](https://developers.google.com/data-manager/api/devguides/audiences/display-video/customer-match/upgrade) for an improved developer experience and access to additional features. We don't recommend implementing new Customer Match workflows using the Display \& Video 360 API.

First-party and partner audiences are user lists that use provided data. The
[audience type](https://developers.google.com/display-video/api/reference/rest/current/firstPartyAndPartnerAudiences#AudienceType) defines the data used to build the audience.

These are [`FirstPartyAndPartnerAudience`](https://developers.google.com/display-video/api/reference/rest/current/firstPartyAndPartnerAudiences#FirstPartyAndPartnerAudience) resources in the API.
Get these audiences using the `firstPartyAndPartnerAudiences` service. The
service will only give access to audiences available to the given advertiser or
partner.

> [!NOTE]
> **Note:** [Estimated audience size fields](https://developers.google.com/display-video/api/reference/rest/current/firstPartyAndPartnerAudiences#FirstPartyAndPartnerAudience.FIELDS.display_audience_size) will only be included when using the [`get`](https://developers.google.com/display-video/api/reference/rest/current/firstPartyAndPartnerAudiences/get) method.

The Display \& Video 360 API supports creating and updating Customer Match audiences. See
more in the [Upload a Customer Match Audience guide](https://developers.google.com/display-video/api/guides/tasks/upload-customer-match-audience/overview).

### Custom lists

[Custom lists](https://support.google.com/displayvideo/answer/7583366) are built in Display \& Video 360 and are based on
given inputs. They group users by interest or purchase intent. They are built in
the Display \& Video 360 UI.

These are [`CustomList`](https://developers.google.com/display-video/api/reference/rest/current/customLists#CustomList) resources in the API. Get these
audiences using the `customLists` service. These audiences can't be created or
updated with the API.

### Combined audiences

[Combined audiences](https://support.google.com/displayvideo/answer/9001225) are created by joining many audiences using
logic operators. They are built in the Display \& Video 360 UI.

These are [`CombinedAudience`](https://developers.google.com/display-video/api/reference/rest/current/combinedAudiences#CombinedAudience) resources in the API. Get
these audiences using the `combinedAudiences` service. These audiences can't be
created or updated with the API.
