Sandboxes · 2 November 2026

API keys limited to a compartment reach only that compartment's sandboxes

On Runtime 2.0, a key limited to one compartment (project) now lists only that compartment's sandboxes, and GET, DELETE, :exec, files, processes and every other sandbox route return 404 for a sandbox in another compartment, the same response as for a sandbox that does not exist. A sandbox created on Runtime 2.0 before this change has no recorded compartment: a compartment's key reaches it only if that key created it. Account-wide keys still reach every sandbox in the account. A create with a name that a sandbox the key cannot reach holds returns 409 name_taken without naming that sandbox, and getOrCreate never returns it.
