Delete file version

Permanently remove an earlier version from history and schedule deletion of its stored content. Storage cleanup may retry in the background. The current version returns 409; revert to another version first. A version that does not exist returns 404.

OAuth scope: api:write.

DELETE/api/v2/files/{fileId}/versions/{version}

Authorization

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.

In: header

Request examples use an API key. For OAuth, replace the X-API-Key header with Authorization: Bearer YOUR_ACCESS_TOKEN.
