Archive removes INBOX; unarchive adds INBOX; mark read removes UNREAD; mark unread adds UNREAD; star adds STARRED; unstar removes STARRED. Supports user label IDs from gmail-labels. Requires gmail.modify, not gmail.labels or gmail.compose. Uses only the calling member's selected connected Google account. Perform writes only when explicitly requested by the user; capability discovery or selection is not authorization. Never automatically retry an uncertain write. ## OpenAPI ````yaml /openapi.json post /v1/capabilities/google-workspace/gmail-message/{messageId}/modify openapi: 3.1.0 info: title: Den API description: >- OpenAPI spec for the Den control plane API. Authentication: - Use `Authorization: Bearer ` for user-authenticated routes that require a Den session. - Use `x-api-key: ` for organization API-key calls. API keys resolve to the issuing user and the organization member they were scoped to when created, so they can call ordinary user and organization routes without a separate signed-in session. Example: `curl https://api.openworklabs.com/v1/me -H "x-api-key: den_..."`. - Session-only flows still require a signed-in user session, including organization creation, invitation acceptance, active-organization switching, and MCP token minting. - Public routes like health and documentation do not require authentication. Swagger tip: use the security schemes in the Authorize dialog to set either `bearerAuth` or `denApiKey` before trying protected endpoints. version: 0.18.46 contact: name: OpenWork url: https://openworklabs.com email: team@openworklabs.com license: name: OpenWork Enterprise Edition License url: https://github.com/different-ai/openwork/blob/dev/ee/LICENSE servers: - url: https://api.openworklabs.com security: - bearerAuth: [] - denApiKey: [] tags: - name: System description: >- Service health, readiness, API documentation, and desktop version metadata. - name: Authentication description: >- Sign-in discovery, administrator bootstrap, OAuth provider connections, and MCP token minting. - name: OAuth description: >- OAuth 2.0 / OpenID Connect authorization-server and protected-resource metadata and dynamic client registration (RFC 8414, RFC 9728, RFC 7591), used by MCP clients. - name: SCIM description: >- SCIM 2.0 provisioning endpoints for identity providers (RFC 7644) and the organization SCIM connector management routes. - name: SSO description: Organization single sign-on connector management routes. - name: Bootstrap description: Agent-first provisional workspace setup routes. - name: Users description: Current user and membership routes. - name: Organizations description: Organization creation, context, brand assets, and install links. - name: Invitations description: Invitation preview, acceptance, creation, and cancellation routes. - name: Members description: Organization member management routes. - name: Roles description: Organization custom role management routes. - name: Teams description: Organization team management routes. - name: API Keys description: Organization API key management routes. - name: Desktop Policies description: Desktop app policies applied to the organization, members, or teams. - name: LLM Providers description: Organization LLM provider catalog, configuration, and access routes. - name: Inference description: Organization inference settings. - name: Cloud description: Organization Cloud instance lifecycle and browser gateway resolution. - name: Workers description: Worker lifecycle, billing, and runtime routes. - name: Worker Runtime description: Worker runtime inspection and upgrade routes. - name: Worker Activity description: Worker heartbeat and activity reporting routes. - name: Automations description: Scheduled Automations, their runs, and desktop runner presence. - name: Workflows description: Saved Workflows (Code Mode scripts), their versions, snapshots, and views. - name: Workflow Runs description: Durable Workflow run history. - name: Codemode Runs description: Generated Artifact views produced by Code Mode runs. - name: Apps description: >- Saved reusable apps built from Workflows and Artifact views, and their sharing. - name: Config Objects description: >- Versioned configuration objects (skills, workflows, and other plugin content). - name: Plugins description: Plugin packages, access grants, and imports. - name: Marketplaces description: Marketplaces that distribute plugins to members and teams. - name: Resources description: >- Aggregated snapshot of the resources and marketplace capabilities available to the caller. - name: Dashboards description: Shared dashboards and their access grants. - name: Capability Sources description: >- Native provider capabilities (Google Workspace, Microsoft 365) and external MCP connections executed as the calling member. - name: Direct uploads description: Multipart uploads that stream workspace files straight to a provider. - name: Connectors description: >- Connector accounts and instances (GitHub and other sources) and their sync state. - name: GitHub description: >- GitHub App installation, repository discovery, and plugin import from GitHub. - name: Diagnostics description: Controlled egress diagnostics for self-hosted deployments. - name: Telemetry description: Telemetry event ingestion and adoption analytics. - name: Webhooks description: Signed inbound webhooks from third-party providers. - name: Admin description: Platform administration routes for allowlisted OpenWork administrators. - name: Deprecated description: Removed features that answer with 410 or an empty result for old clients. paths: /v1/capabilities/google-workspace/gmail-message/{messageId}/modify: post: tags: - Capability Sources summary: >- Archive, unarchive, mark read or unread, star or change Gmail message labels description: >- Changes labels on one message.
