Google Admin SDK Integration Guide
Connect Google Workspace administration data and operations to enterprise systems through REST APIs, OAuth 2.0, selected push notifications, and scheduled workflows.
Google Admin SDK integration options at a glance
Google Admin SDK is primarily a versioned REST and JSON interface covering the Directory, Reports, Data Transfer, Licensing, and related administrative services. Martini can consume these APIs using OAuth 2.0, including service-account domain-wide delegation and administrator impersonation, then handle pagination, transformations, validation, and downstream writes. Selected resources support Google API push notification channels, although coverage is not universal and notifications generally require a follow-up API read. Batch requests and service-specific asynchronous operations are available for supported endpoints. Reports API activity data can be polled and normalized into databases, warehouses, SIEMs, or compliance platforms, while file operations require separate Google Drive APIs.
| Integration point | Supported by Google Admin SDK? | Common use cases | How Martini supports it |
|---|---|---|---|
| REST APIs | Yes | Directory, Reports, Data Transfer, Licensing, and related administrative operations use HTTPS, JSON, resource-oriented URLs, query parameters, and standard HTTP responses. | Martini can consume the documented REST endpoints, manage request configuration, paginate through responses, map JSON resources, and expose reusable APIs or workflows. |
| Webhooks / outbound callbacks | Limited | Google API notification channels provide push-style notifications for selected Directory resources and supported Reports API notification scenarios. They do not cover every administrative change. | Martini can expose an API endpoint or webhook workflow to receive notifications, then retrieve the current resource and reconcile duplicates, missed notifications, and channel renewal. |
| Bulk / async / batch APIs | Limited | Google API batch requests can reduce HTTP overhead for supported clients and operations. Data Transfer and other services may provide service-specific asynchronous or staged operations. | Martini can orchestrate independent requests, bounded concurrency, polling, and per-operation retry handling, without assuming batch requests are transactional. |
| Authentication | Yes | OAuth 2.0 is required for protected administrative operations. Service accounts with domain-wide delegation and administrator impersonation are common for server-side integrations. | Martini can store credentials and configuration securely, consume OAuth-protected APIs, and apply environment-specific scopes and delegated administrator settings. |
| Database / analytics access | Limited | The Reports API provides audit and usage Activities for supported Workspace services, but Google Admin SDK does not provide direct SQL or database access. | Martini can retrieve paginated report data, normalize activity schemas, and write the results to a database, warehouse, SIEM, or compliance repository. |
| SDKs and client libraries | Yes | Google publishes client libraries and discovery-based tooling for its APIs, although the underlying Admin SDK integration remains API-based. | Martini can consume the documented REST endpoints directly and implement reusable workflows for pagination, transformation, retries, and downstream delivery. |
| File / attachment APIs | No | Google Admin SDK is not a general file or attachment API. File migration and synchronization generally require separate Google Drive APIs. | Martini can orchestrate separate Drive API integrations when required, while keeping file operations distinct from Admin SDK administration. |
How Google Admin SDK exposes data and business events
Google Admin SDK REST APIs
Google Admin SDK is primarily delivered through versioned HTTPS REST APIs with JSON request and response bodies. The Directory API covers Users, Groups, Group Members, Organizational Units, Devices, Domains, and related resources, while Reports, Data Transfer, and Licensing APIs address other administrative use cases.
Martini implementation pattern
Martini implementation pattern: Martini authenticates with OAuth 2.0, invokes the appropriate resource endpoint, follows page tokens, validates the response, maps the Google JSON model to a canonical structure, and writes or exposes the result through a controlled workflow or API.
Implementation sequence
Google push notifications
Google API notification channels provide push-style notifications for selected resources and services, including supported Directory changes and Reports API notification scenarios. A notification indicates that data may have changed and does not universally contain the complete changed object.
Martini implementation pattern
Martini implementation pattern: Martini exposes a controlled receiving endpoint, validates the notification and channel context, retrieves the current resource or changes through the Admin SDK, and combines push processing with scheduled reconciliation for missed, duplicate, expired, or unsupported notifications.
Implementation sequence
Reports API activity retrieval
The Reports API provides audit and usage Activities for supported Google Workspace services. Activity availability can be delayed, schemas vary by service, and the API is not direct database access.
Martini implementation pattern
Martini implementation pattern: Martini runs a scheduled workflow over overlapping time windows, follows pagination, normalizes service-specific event parameters, deduplicates activity data, and writes it to a SIEM, warehouse, monitoring platform, or compliance repository.
Implementation sequence
Google API batch requests
Google API batch request patterns can reduce HTTP overhead for supported clients and operations, but they do not necessarily make underlying administrative changes transactional. Support varies by service and endpoint.
Martini implementation pattern
Martini implementation pattern: Martini groups compatible independent operations when appropriate, processes each result separately, applies bounded concurrency, and retains per-operation outcomes so transient failures can be retried without replaying successful work.
Implementation sequence
Common Google Admin SDK integration patterns
Pattern 1: Synchronize Google Workspace users
When to use this pattern
Use this pattern when an identity, HR, or IT platform needs a current view of Google Workspace Users or when approved lifecycle actions must be applied to Google accounts. It supports scheduled reconciliation and optional selected-resource notifications.
Integration direction
Example Mapping
| Google Admin SDK Field | Canonical Field | Target Field |
|---|---|---|
| primaryEmail | user.email | |
| suspended | user.lifecycleStatus | active |
| orgUnitPath | user.organizationalUnit | departmentPath |
| name.fullName | user.displayName | name |
Martini implementation pattern
A Martini workflow retrieves paginated Users, maps profile and lifecycle fields, compares stable identifiers and current state, and applies business rules before upserting the target. Updates back to Google are restricted to approved actions such as suspension or attribute changes, with idempotency checks, authorization validation, and retry handling for transient API responses.
Martini capabilities used
- workflows
- API consumption
- OAuth configuration
- pagination handling
- data mapping
- business rules
- error handling
Pattern 2: Govern Google Groups and membership
When to use this pattern
Use this pattern when an authoritative identity or governance system controls Google Groups and Group Members, or when downstream systems need an auditable view of group access. The workflow distinguishes additions, removals, role changes, and externally managed groups.
Integration direction
Example Mapping
| Google Admin SDK Field | Canonical Field | Target Field |
|---|---|---|
| group.address | ||
| description | group.description | description |
| members[].email | group.members[].principal | memberEmail |
| members[].role | group.members[].role | role |
Martini implementation pattern
Martini receives or retrieves the desired membership state, reads current Google membership, computes a safe difference, and invokes only necessary changes. It protects managed groups with policy checks, records correlation identifiers, handles duplicate requests idempotently, and sends authorization or conflict failures to an exception path.
Martini capabilities used
- workflows
- API consumption
- data mapping
- set comparison
- business rules
- validation
- retry and exception handling
Pattern 3: Build a Google Workspace audit activity pipeline
When to use this pattern
Use this pattern when security, compliance, or analytics teams need normalized Google Workspace audit and usage data. It is appropriate for recurring Reports API collection where activity may arrive late and service-specific event schemas differ.
Integration direction
Example Mapping
| Google Admin SDK Field | Canonical Field | Target Field |
|---|---|---|
| id.time | activity.occurredAt | event_timestamp |
| actor.email | activity.actor | principal |
| events[].name | activity.eventType | event_type |
| events[].parameters | activity.attributes | event_attributes |
Martini implementation pattern
A scheduled Martini workflow polls overlapping time windows, follows page tokens, normalizes Activities and nested event parameters, and deduplicates by activity identifier or a composite key. It writes durable checkpoints only after successful delivery and retries transient quota or server errors without replaying confirmed records.
Martini capabilities used
- scheduler triggers
- workflows
- API consumption
- JSON transformation
- data mapping
- deduplication
- checkpointing
- error handling
Pattern 4: Synchronize organizational units and devices
When to use this pattern
Use this pattern when an IT asset, compliance, or reporting platform needs Workspace organizational context and supported managed device inventory. Scheduled reconciliation is preferred because push coverage is not complete for every desired device or organizational-unit change.
Integration direction
Example Mapping
| Google Admin SDK Field | Canonical Field | Target Field |
|---|---|---|
| orgUnitPath | organizationalUnit.path | u_organizational_unit |
| deviceId | device.externalId | u_device_id |
| serialNumber | device.serialNumber | serial_number |
| status | device.lifecycleStatus | install_status |
Martini implementation pattern
Martini retrieves Organizational Units and Devices in separate paginated flows, normalizes resource-specific fields, enriches device rows with organizational context where available, and writes idempotent inventory updates. The workflow controls concurrency, records partial failures, and performs periodic reconciliation to correct missed changes.
Martini capabilities used
- scheduled workflows
- API consumption
- pagination handling
- data mapping
- enrichment
- controlled concurrency
- monitoring
Applications commonly integrated with Google Admin SDK
Google Admin SDK data is often coordinated with identity, service management, collaboration, and reporting platforms. The exact direction and scope depend on the organization’s authoritative system, Google Workspace permissions, and the administrative actions approved for automation.
| Application | Scenario | Direction | Martini Pattern |
|---|---|---|---|
| ServiceNow | Synchronize Google Workspace users, groups, devices, and audit activity with service management, CMDB, access governance, and incident workflows. | Google Admin SDK → Martini → ServiceNow | Martini retrieves paginated Directory and Reports API resources, normalizes them into ServiceNow payloads, applies field and status rules, and writes changes with retry and exception handling. Approved ServiceNow requests can be validated before invoking Google administrative operations. |
| Salesforce | Coordinate Google Workspace user status, ownership metadata, or group-based access information with Salesforce users and operational records. | Google Admin SDK → Martini → Salesforce | A scheduled Martini workflow reads Users, Groups, or relevant Activities, maps stable Google identifiers and lifecycle fields to Salesforce objects, and applies idempotent upsert rules. Separate guarded workflows can process approved downstream-to-Google actions. |
| Okta | Coordinate identity lifecycle, group membership, and application access between Google Workspace and a central identity platform. | Okta → Martini → Google Admin SDK | Martini receives or polls approved identity changes, compares desired and current Google state, and updates Users or Group Members only when required. It records correlation data and avoids destructive actions without explicit business rules. |
| Microsoft Entra ID | Support coexistence, directory synchronization, and identity governance between Microsoft and Google environments. | Microsoft Entra ID → Martini → Google Admin SDK | Martini maps user and group attributes between the two directory models, resolves ownership and lifecycle conflicts, and orchestrates bounded updates using OAuth credentials and delegated administrative permissions. |
| Jira | Use Workspace user and group information for account governance, project access administration, or audit reporting. | Google Admin SDK → Martini → Jira | Martini periodically retrieves Google users, groups, and selected Activities, transforms them into Jira administration or reporting payloads, and routes validation failures and API errors to an exception path. |
| Slack | Coordinate user lifecycle, group-based access, and offboarding workflows across Google Workspace and Slack. | Google Admin SDK → Martini → Slack | A Martini workflow detects or reconciles Google user status changes, applies policy checks, and calls Slack APIs for approved lifecycle actions while preserving stable identifiers and retrying only transient failures. |
| Google Drive | Combine administrative user, group, domain, and sharing governance with separate Google Drive file and permission APIs. | Google Admin SDK → Martini → Google Drive | Martini orchestrates Admin SDK and Drive API calls in one workflow, using Admin SDK resources for identity and organizational context while using Drive APIs for file or sharing operations. The workflow applies least-privilege scopes and audit logging. |
| Gmail | Correlate Workspace user administration and audit activity with mailbox-related operational or compliance workflows. | Google Admin SDK → Martini → Gmail | Martini combines Directory or Reports API data with separately authenticated Gmail API calls, transforms the results into a controlled downstream model, and restricts mailbox-related operations through explicit authorization rules. |

Common Google Admin SDK data objects used in integrations
| Object | Typical Use | Common target systems | Martini handling |
|---|---|---|---|
| Users | Synchronize Workspace identities, profiles, aliases, organizational information, suspension state, and account lifecycle changes. | Okta, Microsoft Entra ID, ServiceNow, Salesforce, Slack | Martini retrieves paginated Users, uses stable identifiers, maps optional fields, compares desired and current state, and applies guarded updates or downstream upserts. |
| Groups | Govern Google Groups, access collections, collaboration structures, and group-level administration. | Okta, Microsoft Entra ID, ServiceNow, Slack, Jira | Martini retrieves Groups, normalizes names and identifiers, applies ownership and governance rules, and routes approved changes through idempotent workflows. |
| Group Members | Manage or report user, group, and other membership relationships within Google Groups. | Identity platforms, access governance systems, ServiceNow, compliance repositories | Martini checks current membership before adding, removing, or changing roles, records operation outcomes, and handles duplicate or out-of-order notifications. |
| Organizational Units | Represent the Workspace administrative hierarchy used to apply policies and organize users and devices. | ServiceNow, identity governance platforms, reporting databases | Martini retrieves and maps organizational paths and identifiers, validates hierarchy-dependent rules, and synchronizes normalized organizational context. |
| Devices | Inventory supported ChromeOS, mobile, and other managed device resources for compliance and asset processes. | ServiceNow, asset platforms, compliance repositories, data warehouses | Martini performs scheduled retrieval, follows page tokens, normalizes device-specific fields, and sends inventory updates with reconciliation and retry controls. |
| Activities | Capture Google Workspace audit and usage activity from the Reports API for security, compliance, and operational analysis. | SIEMs, data warehouses, monitoring platforms, compliance repositories | Martini polls overlapping time windows, follows pagination, deduplicates by activity identifiers or composite keys, and persists a processing checkpoint. |
Authentication and security considerations
OAuth 2.0 and delegated administration
Google Admin SDK protected operations use OAuth 2.0. Server-to-server integrations commonly use a service account with Google Workspace domain-wide delegation and administrator impersonation.
- Request only the scopes required for each workflow.
- Confirm that the delegated administrator has the required Workspace privileges.
- Store service-account credentials and OAuth configuration in Martini secrets or secure environment configuration.
- Separate development, test, and production projects and domains where practical.
- Restrict logs and retained data because identity, device, and audit information may be sensitive.
Operational considerations for Google Admin SDK integrations
Quotas, pagination, and retries
Google APIs apply project, user, customer, and service-specific quotas. Workflows should use controlled concurrency, follow page tokens, and apply bounded exponential backoff for 429 and transient 5xx responses.
Push notification reliability
Selected notification channels can expire, duplicate notifications, arrive out of order, or miss changes. Use follow-up reads and periodic reconciliation rather than treating notifications as a complete event ledger.
Reports and schema management
Reports API Activities may arrive late and contain service-specific event parameters. Use overlapping polling windows, durable checkpoints, deduplication, optional-field handling, and version-aware mappings.
Safe administrative changes
Compare current and desired state before changing Users, Groups, Group Members, or Devices. Apply explicit authorization, idempotency, approval, and exception rules for consequential operations.
Why use Martini instead of scripts or point-to-point integrations?
Orchestration beyond one-off scripts
Martini provides a maintainable workflow layer for authentication, pagination, transformation, business rules, downstream delivery, and exception handling around Google Admin SDK APIs.
Reusable integration assets
Teams can expose controlled Martini APIs, reuse mappings and validation logic, and combine Google administration with databases, applications, files, or other APIs without duplicating point-to-point code.
Operational control
Scheduled reconciliation, selected push-notification handling, checkpoints, bounded retries, and monitoring provide a more reliable operating model than isolated scripts. Martini also keeps administrative write operations behind explicit validation and authorization rules.
Frequently asked questions
Google Admin SDK is integrated primarily through HTTPS REST APIs using JSON and OAuth 2.0. Enterprise workflows can consume Directory, Reports, Data Transfer, Licensing, and related administrative resources, use selected Google push notification channels, and run scheduled reconciliation for resources without complete event coverage.
Yes. Martini can consume Google Admin SDK REST APIs using OAuth 2.0, including service-account domain-wide delegation and administrator impersonation. It can also receive selected Google push notifications, orchestrate scheduled synchronization, transform Google JSON resources, and deliver results to applications, databases, or APIs.
No. A dedicated Google Admin SDK connector is not required. Martini can integrate using the Admin SDK’s native REST APIs, OAuth 2.0 authentication, selected push notification channels, and service-specific batch or reporting endpoints.
Lonti does not charge an additional per-connector or per-vendor fee to integrate Google Admin SDK. The integration is subject to the provisioned capacity of the Martini environment. Separate costs may apply from Google, Google Cloud, infrastructure providers, or other third parties based on subscription, usage, and deployment model.
Use the REST APIs as the primary integration method. OAuth 2.0 is required for protected administrative operations, with domain-wide delegation commonly used for server-side administration. Selected resources support push notification channels, while Reports API collection and broader reconciliation are typically scheduled.
Google supports push notification channels for selected resources and services, but not a universal event stream for every administrative operation. Notifications generally indicate that a resource may have changed, so Martini should retrieve the current resource and use reconciliation to handle duplicates, missed notifications, expiration, and limited coverage.
Martini can retrieve paginated Users, Groups, Group Members, Organizational Units, Devices, or Activities, map them to a canonical model, apply business rules, and write target-specific payloads. Scheduled workflows can persist checkpoints, use overlapping Reports API windows, and compare current and desired state before administrative updates.
Martini workflows can distinguish authorization, validation, missing-resource, conflict, quota, and temporary server errors. Transient 429 and 5xx responses should use bounded exponential backoff, while non-transient failures should be routed for correction. Idempotent comparisons, stable identifiers, activity keys, and checkpoints help prevent duplicate effects.
