Create File Upload Part URLs

Create signed URLs for a bounded set of multipart upload part numbers.

POST/api/v2/files/uploads/{uploadId}/parts

Authorization

apiKey
X-API-Key<token>

Your Sim API key, personal or workspace-scoped. Generate one from the Sim dashboard under Settings > API Keys. A workspace API key is not accepted everywhere: operations that act on behalf of a specific human — administrative reads, secret access, and irreversible or governance-affecting writes — always reject it, whatever role the key carries. Each such operation says so in its own description, and the rejection surfaces as 403 unless the operation conceals unauthorized resources, in which case it is reported as 404. Use a personal API key for those.
