Find removed documents with `GET /vaults/{id}/documents?include_deleted=true`. Restoring works on the upload, so every row that shares this row's `file_id` comes back with it. A restore that would put the vault over its document limit is refused whole with `403`, and nothing comes back. Restoring a document that is already live returns `200`, so a retried call is safe. Requires the `editor` or `owner` role in the vault and the organization-level permission to manage vaults. Requires a user-scoped API key (`u:gcai_...`). A vault is shared with named people, so an organization-scoped key has no identity to resolve vault access with. ## OpenAPI ````yaml POST /vaults/{id}/documents/{documentId}/restore openapi: 3.0.3 info: title: GC AI External API version: 1.0.0 description: >- The GC AI External API allows programmatic access to GC AI's chat capabilities. It's designed for integration with workflow automation tools like Zapier, Make, n8n, or custom applications. ## Authentication All API requests must include an API key in the `Authorization` header: ``` Authorization: gcai_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx ``` API keys can be created in the GC AI app under **Settings → API**. ## Multi-turn Conversations Conversations can span multiple turns: pass the `chat_id` returned by a completion back on your next request to continue the same chat. See [Multi-turn Conversations](/api-reference/concepts/multi-turn). ## Current Limitations The following is not yet available via API: - **Interactive clarification**: the model cannot pause to ask the caller a follow-up question; the `askUserQuestions` tool is disabled on the API surface ## Usage Usage is tracked and viewable in the GC AI app under **Settings → API → View Usage**. ## Support For API support, contact [support@gc.ai](mailto:support@gc.ai) or reach out to your account representative. contact: email: support@gc.ai servers: - url: https://app.gc.ai/api/external/v1 description: Production server security: [] tags: - name: Async Jobs description: Poll the status and result of asynchronous API jobs - name: Chat description: AI chat completion endpoints - name: Chats description: Chat management, message history, and sharing endpoints - name: Contract Intelligence description: Vault discovery and document ingestion endpoints for Contract Intelligence - name: Files description: File upload and management endpoints - name: Folders description: Folder management endpoints - name: Playbooks description: Playbook review endpoints - name: Profiles description: Personal and company profile endpoints - name: Projects description: Project management endpoints - name: Skills description: Skill library management endpoints - name: Utility description: Health check and connectivity endpoints - name: Usage description: Usage and credit/billing reporting endpoints paths: /vaults/{id}/documents/{documentId}/restore: post: tags: - Contract Intelligence summary: Restore a removed document description: >- Bring a removed document back into the vault table with the values it already had.
