# Get an SMS outbound operation's full delivery/reconciliation tree

`GET /v1/sms/operations/{operation_id}`

## Path parameters

## Response `200`

Successful Response

- SmsOutboundOperationDetail — Full operation -> chunks -> attempts -> events tree for ``GET /sms/operations/{operation_id}``. ``outcome`` doesn't exist on the ORM operation directly (derived) — defaulted here so ``model_validate`` succeeds, then always overwritten by the router before the response is returned.
