Index Workspace Files

Index files the workspace already stores, without re-uploading their bytes. Each reference is authorized against the file it names, so a reference the caller cannot read, one over the 100 MB document limit, or one whose type is not supported is reported in failed while the rest are queued — a partial outcome is a 200, not a multi-status. A queued document starts in the pending processing state; the entries returned here carry only its identity, so read GET /api/v2/knowledge/{knowledgeBaseId}/documents/{documentId} for its current state. A workspace API key is rejected with 403; use a personal API key.

POST/api/v2/knowledge/{knowledgeBaseId}/documents/from-workspace-files

Authorization

apiKey
X-API-Key<token>

Your Sim API key, personal or workspace-scoped. Generate one under Settings, then API Keys. Operations that reject workspace keys say so in their own description.
