Google has quietly turned Google Analytics access management into a programmable surface. On September 18, 2026, the alpha Google Marketing Platform Admin API gained 14 new methods for user groups, membership and organization-level roles. Google Analytics followed with a release note on October 5 describing the same capability as the “User Groups Admin API.”
What the 14 methods actually do
The methods fall into three buckets:
- User groups — GetUserGroup, ListUserGroups, CreateUserGroup, UpdateUserGroup and DeleteUserGroup manage groups inside a Google Marketing Platform organization.
- Membership — GetUserGroupMember, ListUserGroupMembers, CreateUserGroupMember, UpdateUserGroupMember and DeleteUserGroupMember add, update and remove users or other groups. A member can itself be a group, so hierarchies are possible.
- Admin access bindings — GetAdminAccessBinding, ListAdminAccessBindings, CreateAdminAccessBinding and UpdateAdminAccessBinding grant organization admin, user admin and billing admin roles to a user or group.
Notably, there is no DeleteAdminAccessBinding method in either the changelog or the REST reference. That leaves a real gap for offboarding: you can grant an organization admin role through code, but Google does not document a single call to take one away.
Why it matters for agencies and large teams
This is aimed squarely at organizations that manage access at scale. Instead of adding or removing dozens of users one by one in Analytics settings, a team can create a group once, bind a role to the group, and then update membership as people join or leave. The help page puts it simply:
“User groups simplify the process of managing access for large teams.”
For agencies rotating staff across client properties and in-house teams running joiner-leaver workflows from an identity system, that is a meaningful automation win. It also makes API credentials more valuable: anyone holding User Admin or Org Admin rights can now make org-level changes at script speed.
The API push arrives in a year when Google has tightened access elsewhere: passkeys for sensitive Google Ads actions and second-admin approval for user removals. This Analytics update removes manual work rather than adding friction, but the security trade-off is the same: the credentials that automate access become a bigger target.
The alpha caveat
The API remains in alpha, where Google says method names, fields and behavior may change without the deprecation windows stable versions get. It has been in alpha since March 6, 2024 — 31 months at the time of this update — and no v1beta or v1 has followed.
There are also mismatches between Google’s pages. The developer reference names the service Google Marketing Platform Admin API; the Analytics note calls it a User Groups Admin API. The Analytics note mentions property and account access, while the reference shows all bindings at the organization level. The overview page still describes the API’s older link and service-level functions only.
Before building anything on this, audit who holds User Admin or Org Admin permissions, keep credentials tightly scoped, and confirm how role removal is handled in practice. An API that can assign an org admin faster than it can remove one deserves a careful look.
