Copy an app into a new private app owned by the caller
Creates the caller a private copy of an app they can edit, or of a Template they may copy, without sending its source. A Template copy records the source as its origin (copyKind: "template"). The copy keeps the source code, styles, icon, and network settings; it never carries sharing, Public, signed-in access, Template or Listed state, tokens, secrets, Routines, Webhooks, custom domains, or version history. Without manifest_id the copy takes the next free manifest id after the source’s (<id>-2, <id>-3); a manifest_id the caller already holds is refused with 409 rather than replacing that app. include_data: true also copies the stored data and assets in the same transaction that creates the copy, so a copy exists with all of its data or not at all; it needs owner access to a personally owned source (a team app’s data is not copied into a personal account), and the data must fit the 24 MiB a copy carries, the per-app caps, and the caller’s storage allowance. Without idempotency_key every call creates a new copy and answers 200 with it; a retry with the same key answers with the copy, or the pending build, the first call made, and the same key with a different source, include_data, or manifest_id answers 409 idempotency_conflict. A 409 manifest_id_conflict names the app holding the id in existingAppId when one does. An ESM app copies through a build; a build that does not publish at once answers 202 with its build status, and the data copies when it publishes. secretsNotCopied names the source secrets to set on the copy; it is reported only to callers who can manage the source’s secrets.
/app/{id}/copyAuthorizationBearer token (chrm_user_*) · headerrequiredUser-scoped personal access token. Mint via POST /api/token after signing in, or via the device-pairing flow at POST /api/pair/start. Accepted by every operation that lists userToken in its security; operations that list only sessionCookie refuse it with 401 unauthorized.
idstringrequiredapplication/jsonmanifest_idstringManifest id for the copy. Must be free for the caller. Omit it to take the next free id.
display_namestringDisplay name for the copy. Defaults to the source's. Refused for ESM apps, which take their name from manifest.meta.name.
idempotency_keystringNames this copy so a retry returns it instead of making another. The same key with a different source, include_data, or manifest_id answers 409 idempotency_conflict.
include_databooleanAlso copy the stored data and assets. Defaults to false. Needs owner access to a personally owned source; a team app’s data is not copied.

freeprobusinessenterpriselimitstring | integerWhich ceiling the call met, keyed by kind. A plan refusal (*_limit_exceeded) names the countable that ran out — version_history, routines_per_app, routines_per_owner, webhooks_per_app, webhooks_per_owner — and pairs it with max. An app_busy refusal names the bound it met and pairs it with observed and allowed; no plan lifts any of them. Two are per-app run bounds, concurrent_runs and runs_per_window; the third, render_token_refresh, is the page render asking for a new render-token secret, held by 10 per app per client IP and 60 per app across every address in a 60 second window, and observed/allowed name whichever of those two refused. An edits_too_large rejection carries the numeric cap that was exceeded instead of a name.
rungstringOn an app_busy refusal, how hard the app's own refusal ladder is refusing: throttled is the plain ceiling breach above; parked means a caller kept calling inside a wait it was given, so the server mints its own Retry-After (doubling from 60s to a 300s cap) and refuses until a quiet window passes even once the ceiling clears; closed is the same, plus the response closes the connection. Absent on every other kind.
