The latest release of the Data Manager API introduces features that simplify audience management, enhance ingestion workflows with field-level warnings, and enable more granular user-provided data for Google Analytics.

Remove all audience members

Use the new RemoveAllAudienceMembers method to clear all members from specified user lists in a single operation. The optional removeAsOfTime parameter lets you target only those members added before a specific timestamp.

This is particularly useful when you need to perform a full refresh (or "replace all") of your audience data, allowing you to clear the existing list and populate it with a new set of users.

Ingestion field warnings

Data Manager API ingestion responses now include detailed field-level warnings for validation issues on optional fields. If the API detects validation issues with optional fields, your ingestion request will succeed and the rest of your ingestion data will still be processed. Validation failures for required fields will continue to fail the entire request following the fast-fail model.

If any optional field you provide is invalid, the response from IngestEventsRequest or IngestAudienceMembersRequest includes a field_warnings field with a list of FieldWarning objects. Each warning provides a specific reason (WarningReason), a descriptive message, and the location of the field in the request where the issue occurred.

Additional address data for Google Analytics events

You can now provide additional user address information when ingesting events to Google Analytics destinations. Along with the given_name, family_name, region_code, and postal_code fields, AddressInfo resource now supports:

• address_line (street address)
• city
• administrative_area (state or province)

Also, you can now use the existing user-provided data (user_data) field to meet the Identifiers requirement for multi-source events sent to web data streams. This gives you another option when you don't have the ad_identifiers.gclid, user_id, or client_id for a multi-source event.
