POST http://localhost:3000/service_management/saveInstances
Content-Type: application/json

Creates a new service instance or update an existing service instance.

Reference: https://docs.itential.com/itential-platform/2023-2/api-reference/service-management/service-cog-save-instances

## Authentication

- `Authorization` header (basic auth, required) — Basic authentication of the form `Basic <base64(username:password)>`.

## Request

### Body (application/json)

This endpoint expects an object.

- `instance` (object, optional)
  - `servicePath` (list of object, optional) — The servicePath key is a service model's XPATH. The value is an array of objects. Each array element represents an instance of a service model.
- `options` (object or object, optional)
  - Service Instance Options
    - `skip-validation` (any, optional) — Required to enable commit flag support.
    - `dryrun` (object, optional) — Use dryrun commit flag. If not dryrun is not set when running testInstances, it will be added with outformat defaulting to native.
      - `outformat` (enum, optional)
        - Allowed values: `cli`, `native`, `xml`
      - `reverse` (any, optional) — Used with native outformat, this flag displays device commands for getting back to current running state in the network if the commit succeeds.
    - `commit-queue` (object, optional)
      - `tag` (string, optional) — User defined opaque tag which is present in all notifications and events sent referencing the specific queue item. This property must be placed first inside the commit-queue property if being used.
      - `sync` (object or object, optional) — Uses sync mode for commit queue. Cannot be used with async or bypass mode.
        - object
          - `timeout` (integer, optional) — Maximum number of seconds to wait for transaction to be committed.
        - object
          - `infinity` (any, optional) — Use this format for infinite wait time.
      - `async` (any, optional) — Uses async mode for commit queue. Cannot be used with sync or bypass mode.
      - `bypass` (any, optional) — Uses bypass mode for commit queue. Cannot be used with sync or async mode.
      - `block-others` (any, optional) — The commit-queue-block-others flag will block subsequent queue items, which use any of the devices in this queue item, from being queued.
      - `lock` (any, optional) — The commit-queue-lock flag will place a lock on the resulting queue item.
      - `atomic` (boolean, optional) — The commit-queue-atomic sets atomic behavior of resulting queue item.
      - `error-option` (enum, optional) — The commit-queue-error-option flag determines behavior on error.
        - Allowed values: `continue-on-error`, `rollback-on-error`, `stop-on-error`
    - `no-deploy` (any, optional) — The no-deploy flag makes a commit without invoking the service create method.
    - `no-revision-drop` (any, optional) — Uses no-revision-drop flag. Forces NSO to not silently drop data set operations.
    - `no-networking` (any, optional) — The no-networking flag does not send data to the devices.
    - `no-out-of-sync-check` (any, optional) — The no-out-of-sync-check flag continues with a transaction even when NSO detect an out of sync device. Can't be used with no-overwrite flag.
    - `no-overwrite` (any, optional) — The no-overwrite flag checks that the data that should be modified has not changed on the device compared to NSO's view of the data. Can't be used with no-out-of-sync-check.
    - `use-lsa` (any, optional) — The use-lsa flag forces handling of LSA nodes as such. Propogates the following flags, if used, to LSA nodes but not upper NSO node: dry-run, no-networking, no-out-of-sync-check, no-overwrite, no-revision-drop.
    - `no-lsa` (any, optional) — The no-lsa flag will not handle LSA nodes as such.
  - Save Instance Options (old)
    - `sync` (boolean, optional) — Set to false to use commit-queue async mode if global Commit Queue property is set to true (default).
    - `commit-sync` (boolean, optional) — Use commit-queue sync mode.
    - `no_overwrite` (boolean, optional) — Use no-overwrite commit flag.
    - `staging` (boolean, optional) — Use no-networking commit flag.
    - `force` (boolean, optional) — Use no-out-of-sync-check commit flag.
