Restricting GAM API Access by Advertiser

[Pasha]

Hi Team,

I’d like to clarify if the Ad Manager API can be restricted at an advertiser level. Specifically, we want to know whether it’s possible to configure API access for a user (or service account) so that:

• The user can only query data related to a specific advertiser.

• They are unable to access data, reports, or entities belonging to other advertisers within the same GAM network.

We are aware that roles and teams can be used to limit access in the GAM UI, but we’d like to confirm if the same level of restriction applies consistently when accessing data through the API.

Could you please confirm whether this is supported, and if so, share the best-practice steps to configure it?

Thank you for your guidance.

Thanks,

Chand

Hi,

Thank you for contacting the Ad Manager API support team.

The roles and teams restrictions that are configured in the Ad Manager UI apply to the Ad Manager API also. If a user or service account is assigned to a team that only has access to a specific Advertiser, then when using the API that account will also be restricted to querying only the data they are allowed see in the UI.

They will not be able to pull reports or entities related to other advertisers outside their assigned teams. You may refer to this article for more information.

Thanks,
 

Ad Manager API Team
