The [latest release of the Data Manager API](https://developers.google.com/data-manager/api/reference.md.txt?utm_source=googleblog-adsdevs&utm_medium=blog&utm_campaign=adr-dm-api-r6&utm_content=learnmore-changelog#2026-07-30_v18)
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**

<br />


Use the new
[RemoveAllAudienceMembers](https://developers.google.com/data-manager/api/reference/rpc/google.ads.datamanager.v1.md.txt#google.ads.datamanager.v1.IngestionService.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](https://developers.google.com/data-manager/api/devguides/concepts/understand-errors.md.txt?utm_campaign=adr-dm-api-r6&utm_source=googleblog-adsdevs&utm_medium=blog&utm_content=learnmore-fastfail#fast-fail).


If any optional field you provide is invalid, the response from
[IngestEventsRequest](https://developers.google.com/data-manager/api/reference/rpc/google.ads.datamanager.v1.md.txt?utm_campaign=adr-dm-api-r6&utm_source=googleblog-adsdevs&utm_medium=blog&utm_content=learnmore-refdocs#ingesteventsrequest)
or
[IngestAudienceMembersRequest](https://developers.google.com/data-manager/api/reference/rpc/google.ads.datamanager.v1.md.txt?utm_campaign=adr-dm-api-r6&utm_source=googleblog-adsdevs&utm_medium=blog&utm_content=learnmore-refdocs#ingestaudiencemembersrequest)
includes a `field_warnings` field with a list of
[FieldWarning](https://developers.google.com/data-manager/api/reference/rpc/google.ads.datamanager.v1.md.txt?utm_campaign=adr-dm-api-r6&utm_source=googleblog-adsdevs&utm_medium=blog&utm_content=learnmore-refdocs#fieldwarning)
objects. Each warning provides a specific reason ([WarningReason](https://developers.google.com/data-manager/api/reference/rpc/google.ads.datamanager.v1.md.txt?utm_campaign=adr-dm-api-r6&utm_source=googleblog-adsdevs&utm_medium=blog&utm_content=learnmore-refdocs#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](https://developers.google.com/data-manager/api/reference/rpc/google.ads.datamanager.v1.md.txt?utm_campaign=adr-dm-api-r6&utm_source=googleblog-adsdevs&utm_medium=blog&utm_content=learnmore-refdocs#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](https://developers.google.com/data-manager/api/devguides/events/send-events#web-data-stream). This gives you another option when you don't have the
`ad_identifiers.gclid`, `user_id`, or
`client_id` for a multi-source event.
