Google Workspace Integration Guide

Connect Google Workspace services such as Gmail, Drive, Calendar, Sheets, and Admin SDK to enterprise applications through REST APIs, OAuth 2.0, and service-specific push notifications.

Google Workspace integration options at a glance

Google Workspace provides service-specific REST APIs for Gmail, Drive, Calendar, Sheets, Docs, Admin SDK, Chat, Meet, and other services. OAuth 2.0 supports user-authorized access, while service accounts with domain-wide delegation support approved organization-wide workflows. Drive, Gmail, Calendar, and selected other services provide push or event-style notifications, although there is no universal Workspace webhook stream. Martini can consume these APIs, receive supported notifications, process Pub/Sub-delivered messages, and run scheduled reconciliation workflows. File uploads, downloads, exports, Gmail attachments, pagination, batch requests, and incremental synchronization can be orchestrated with mappings, business rules, retries, and protected environment configuration.

Integration pointSupported by Google Workspace?Common use casesHow Martini supports it
REST APIsYesGmail, Drive, Calendar, Sheets, Docs, Admin SDK, Chat, and Meet integrations use service-specific JSON-over-HTTPS APIs with pagination, filtering, and partial responses.Martini can consume Google Workspace REST APIs from workflows, map JSON payloads, apply business rules, and expose controlled APIs for upstream systems.
Webhooks and outbound callbacksLimitedDrive, Gmail, Calendar, and selected other services provide resource-specific push or event subscriptions. Coverage is not universal.Martini can expose endpoints or receive supported notification messages, then retrieve the current resource because notifications commonly signal a change rather than contain the full object.
Bulk, asynchronous, and batch APIsLimitedSome Google APIs support HTTP batch requests, while Gmail history, Drive change tokens, and Pub/Sub support incremental or asynchronous processing patterns.Martini can orchestrate batches, pagination, queues, checkpoints, and controlled concurrency, subject to each Google API's supported methods and limits.
File and attachment APIsYesDrive supports multipart and resumable uploads, downloads, metadata updates, permissions, and exports; Gmail supports MIME messages and attachment retrieval.Martini can retrieve, transform, route, and store file content or metadata and can coordinate large-file processing with downstream applications.
AuthenticationYesOAuth 2.0 supports user-authorized access, while service accounts with domain-wide delegation support approved server-to-server and organization-wide workflows.Martini can keep OAuth client details, refresh tokens, service-account credentials, delegated subjects, and scopes in protected environment configuration.
Database and analytics accessLimitedAdmin SDK Reports provides activity and usage analytics, while Google Sheets can act as a document-based data source; Google Workspace does not provide direct relational database access.Martini can consume Reports and Sheets APIs or write normalized data to an appropriate database, without treating Sheets as a transactional database by default.
GraphQL APIsNot confirmedGoogle Workspace documentation is centered on service-specific REST APIs; no general Workspace GraphQL API was confirmed.Martini can use REST APIs instead; GraphQL should not be assumed for Google Workspace services.
SOAP APIsNot confirmedCurrent Workspace integration guidance uses REST APIs and service-specific event mechanisms rather than SOAP.Martini can consume SOAP services generally, but no Google Workspace SOAP integration should be assumed from the supplied research.

How Google Workspace exposes data and business events

Google Workspace REST APIs

Google Workspace services expose separate REST APIs for Gmail, Drive, Calendar, Sheets, Docs, Admin SDK, Chat, Meet, and other products. These APIs generally use JSON over HTTPS and provide resource-specific methods, pagination, filters, and partial responses.

Martini implementation pattern

Martini implementation pattern: a workflow authenticates with OAuth 2.0 or delegated service-account credentials, calls the relevant service API, follows page or synchronization tokens, maps the response, applies business rules, and writes the result to a target system.

Implementation sequence

Authenticate with the required OAuth scopes
Call the service-specific Google Workspace API
Follow pagination or incremental synchronization tokens
Map the Google JSON payload to the target model
Apply validation and business rules
Write the result and record the checkpoint

Google Workspace push notifications

Drive, Gmail, Calendar, and selected other services support resource-specific push or event-style notifications. Gmail notifications can indicate mailbox history changes, while Drive and Calendar notifications indicate that resource state should be retrieved.

Martini implementation pattern

Martini implementation pattern: expose an appropriate endpoint or receive supported Pub/Sub-delivered messages, validate notification context, retrieve current data from Google, and process the changed objects rather than treating the notification as a complete payload.

Implementation sequence

Receive the Google notification or Pub/Sub message
Validate the channel, subscription, or notification context
Retrieve changed Messages, Files, or Events from Google
Deduplicate using stable identifiers or cursors
Map and process the current resource state
Persist the cursor and schedule channel renewal or reconciliation

Google Workspace batch processing

Some Google APIs support HTTP batch requests, and Google services provide incremental or asynchronous mechanisms such as Gmail history identifiers, Drive change tokens, and Pub/Sub buffering. Supported operations and limits vary by API.

Martini implementation pattern

Martini implementation pattern: a workflow divides work into bounded pages or batches, controls concurrency, processes successful and failed items separately, and records checkpoints so a later run can resume without duplicating completed work.

Implementation sequence

Determine the API-supported batch or incremental method
Partition work into bounded requests
Submit requests with controlled concurrency
Process successful and failed responses independently
Persist progress and retry eligible failures
Reconcile incomplete or interrupted batches

Google Workspace files and attachments

Drive provides multipart and resumable uploads, downloads, metadata updates, permissions, and exports. Gmail provides MIME messages, message parts, drafts, threads, and attachment retrieval through its own API.

Martini implementation pattern

Martini implementation pattern: retrieve file or attachment metadata, download or export content when required, transform it into the downstream format, and transfer it to the target while handling large payloads and permission failures.

Implementation sequence

Retrieve file or message-part metadata
Download or export the required content
Validate size, format, and access permissions
Transform content or metadata for the target
Upload or deliver the result
Record source identifiers and processing status

Common Google Workspace integration patterns

Pattern 1: Synchronize directory users and groups

When to use this pattern

Use this pattern when Workday, Okta, Microsoft Entra ID, or ServiceNow must be aligned with Google Workspace directory state for onboarding, organizational changes, suspension, or deprovisioning.

Applications commonly integrated with Google Workspace

Google Workspace can be integrated with named enterprise applications to synchronize directory data, automate business processes, exchange files, and distribute notifications. The exact object coverage and direction depend on the APIs and permissions approved for each application.

Application Scenario Direction Martini Pattern
Salesforce Synchronize contacts, leads, cases, calendar activities, and email-driven customer processes. Google Workspace → Martini → Salesforce Use Gmail and Calendar API workflows to retrieve relevant messages or events, map them to Salesforce objects, apply routing rules, and record message or event identifiers for idempotency. Salesforce updates can be published back through controlled API workflows.
ServiceNow Convert monitored Gmail messages into incidents or requests and synchronize directory users or groups with operational workflows. Google Workspace → Martini → ServiceNow Receive a Gmail notification or run a scheduled mailbox workflow, retrieve the changed Message, extract structured data or attachments, and create or update a ServiceNow record with retry and duplicate controls.
Slack Send Workspace processing results, approvals, alerts, or selected event notifications to collaboration channels. Google Workspace → Martini → Slack Consume Workspace API results or event notifications, transform them into channel messages, apply filtering and approval rules, and call Slack APIs through a reusable Martini workflow.
Jira Create issues from Gmail messages or Sheets-based intake and publish issue status to Workspace users or processes. Google Workspace → Martini → Jira Retrieve qualifying Gmail Messages or Sheets rows, validate required fields, map them to Jira issue data, and optionally send status notifications through Gmail or Calendar workflows.
Zendesk Convert Gmail support messages into tickets and exchange customer-service notifications or attachments. Google Workspace → Martini → Zendesk Use Gmail watch notifications or scheduled polling, retrieve message content and attachments, create Zendesk tickets, label successfully processed Gmail messages, and retain stable identifiers.
Workday Synchronize worker lifecycle data with Google Workspace Users and Groups for provisioning, suspension, and organizational changes. Workday → Martini → Google Workspace Schedule a workflow that compares Workday worker changes with Admin SDK Users and Groups, applies approved lifecycle rules, and calls Google APIs using constrained administrative authorization.
Okta Coordinate identity lifecycle and provisioning between Okta and Google Workspace directory accounts. Okta → Martini → Google Workspace Expose or consume controlled REST APIs for lifecycle events, validate identity state, map users and groups to Admin SDK objects, and maintain an audit trail for provisioning outcomes.
NetSuite Move spreadsheet, Drive, or Gmail-based operational data into finance and order-management processes. Google Workspace → Martini → NetSuite Retrieve Drive Files, export or parse Sheets data, validate and transform rows, then invoke NetSuite APIs with batch handling, reconciliation, and error routing.

Authentication and security considerations

OAuth 2.0 and delegated access

Google Workspace APIs primarily use OAuth 2.0. User-authorized workflows should request only the scopes they require. Organization-wide workflows can use a service account with administrator-approved domain-wide delegation and a constrained impersonated subject.

Scope and permission governance

OAuth scopes do not replace Google Workspace permissions, sharing settings, or administrator roles. Gmail and Drive scopes may be sensitive or restricted and can require consent-screen configuration, verification, or additional security review.

  • Store client credentials, refresh tokens, service-account credentials, delegated subjects, and scopes in protected Martini environment configuration.
  • Grant only the scopes and delegated users required by each workflow.
  • Review delegated access and avoid using an administrator account as a general-purpose integration identity.

Operational considerations for Google Workspace integrations

Quotas and pagination

Google Workspace APIs apply project-level, user-level, and service-specific quotas. Workflows should handle HTTP 429 responses, quota-related 403 responses, retry guidance, exponential backoff, and per-user versus per-project limits. List operations should continue until page tokens are exhausted.

Incremental processing and notifications

Push channels and subscriptions can expire, notifications can be duplicated or delayed, and notifications commonly do not contain complete resource data. Persist channel identifiers, expiration times, history IDs, change tokens, synchronization tokens, and processed identifiers, then retrieve current resources and run reconciliation when necessary.

Data and API behavior

  • Account for permission differences across Gmail, Drive, Calendar, and directory resources.
  • Use resumable transfers or bounded processing for large Drive files and Gmail attachments.
  • Expect service-specific fields, versions, date-time formats, omitted partial-response fields, and evolving enums.
  • Do not retry invalid scopes, missing permissions, malformed requests, or other configuration errors as if they were transient failures.

Why use Martini instead of scripts or point-to-point integrations?

Orchestration instead of isolated scripts

Martini provides a maintainable workflow layer around Google Workspace APIs, notifications, files, and downstream systems. Teams can separate notification intake, resource retrieval, transformation, business rules, target writes, checkpoints, and reconciliation rather than embedding the entire process in a single script.

Reusable integration assets

Martini can consume REST APIs, expose controlled APIs, receive supported webhook-style events, map data between models, and reuse workflow logic across Gmail, Drive, Calendar, Sheets, and Admin SDK scenarios.

  • Centralize protected authentication and environment configuration.
  • Apply consistent pagination, idempotency, retry, validation, and error-routing patterns.
  • Support real-time, event-driven, scheduled, and batch processing in the same integration architecture.
  • Monitor workflow outcomes and retain checkpoints for operational recovery.

Frequently asked questions

How can Google Workspace be integrated with enterprise systems?

Google Workspace can be integrated through service-specific REST APIs for Gmail, Drive, Calendar, Sheets, Docs, Admin SDK, Chat, Meet, and other products. OAuth 2.0, service accounts with domain-wide delegation, selective push notifications, Pub/Sub delivery, scheduled polling, file APIs, and incremental synchronization mechanisms support different integration requirements.

Can Martini integrate with Google Workspace?

Yes. Martini can consume Google Workspace REST APIs, expose controlled APIs for Workspace-related operations, receive supported push notifications or Pub/Sub-delivered messages, process files and attachments, and orchestrate mappings, business rules, retries, and reconciliation workflows.

Do I need a connector to integrate Google Workspace with Martini?

No. A dedicated Google Workspace connector is not required. Martini can use Google Workspace's confirmed native REST APIs, OAuth 2.0 and delegated authentication methods, service-specific notifications, Pub/Sub messages, file APIs, and scheduled workflows.

Is there any extra Lonti cost to integrate Google Workspace with Martini?

Lonti does not charge an additional per-connector or per-vendor fee to integrate Google Workspace. The integration is subject to the provisioned capacity of the Martini environment. Separate costs may apply from Google, cloud infrastructure, or other third-party systems based on subscriptions, API usage, storage, and deployment model.

Which Google Workspace integration methods should be used?

REST APIs are the primary method because each Workspace service exposes its own API and data model. Use OAuth 2.0 for user-authorized access or domain-wide delegation for approved organization-wide operations, and use file APIs, batch methods, or incremental tokens when the service supports them. No general Google Workspace GraphQL or SOAP API was confirmed.

Are Google Workspace webhooks or events available?

Selected services support resource-specific push or event-style notifications. Drive, Gmail, Calendar, and selected other services have different notification models, and Gmail can use mailbox watches with Pub/Sub. These are not a universal Workspace event stream, and notifications generally require a follow-up API call to retrieve current data.

How does synchronization with Google Workspace work?

Martini can run scheduled synchronization or use service-specific incremental mechanisms such as Gmail history identifiers, Drive change tokens, Calendar synchronization tokens, and Reports API filters. Workflows should persist cursors, renew notification channels, handle pagination, and reconcile missed or duplicated notifications.

How does Martini handle Google Workspace mapping, errors, and duplicates?

Martini can map Google JSON, MIME, Sheets, file, and event data into canonical and target-specific models, apply validation and business rules, and route failures for retry or review. Stable identifiers such as Gmail message IDs, Drive file IDs, Calendar event IDs, and synchronization cursors support idempotency. Transient quota and rate-limit responses can use backoff, while permission and scope errors require correction.
