# Get a configuration deployment by ID

`GET /api/unstable/fleet/deployments/{deployment_id}`

Retrieve detailed information about a specific deployment using its unique identifier.
This endpoint returns comprehensive information about a deployment, including:
- Deployment metadata (ID, type, filter query)
- Total number of target hosts
- Current high-level status (pending, running, succeeded, failed)
- Estimated completion time
- Configuration operations that were or are being applied
- Detailed host list: A paginated array of hosts included in this deployment with individual
  host status, current package versions, and any errors

The host list provides visibility into the per-host execution status, allowing you to:
- Monitor which hosts have completed successfully
- Identify hosts that are still in progress
- Investigate failures on specific hosts
- View current package versions installed on each host (including initial, target, and current
  versions for each package)

Pagination: Use the `limit` and `page` query parameters to paginate through hosts. The response
includes pagination metadata in the `meta.hosts` field with information about the current page,
total pages, and total host count. The default page size is 50 hosts, with a maximum of 100.

## Path parameters

- `deployment_id` string, required

## Query parameters

- `limit` integer
- `page` integer

## Response `200`

OK

- FleetDeploymentResponse — Response containing a single deployment.
  - `data` FleetDeployment — A deployment that defines automated configuration changes for a fleet of hosts.
    - `attributes` FleetDeploymentAttributes, required — Attributes of a deployment in the response.
      - `config_operations` FleetDeploymentOperation[] — Ordered list of configuration file operations to perform on the target hosts.
        - `file_op` 'merge-patch' | 'delete', required — Type of file operation to perform on the target configuration file. - `merge-patch`: Merges the provided patch data with the existing configuration file. Creates the file if it doesn't exist. - `delete`: Removes the specified configuration file from the target hosts.
        - `file_path` string, required — Absolute path to the target configuration file on the host.
        - `patch` object — Patch data in JSON format to apply to the configuration file. When using `merge-patch`, this object is merged with the existing configuration, allowing you to add, update, or override specific fields without replacing the entire file. The structure must match the target configuration file format (for example, YAML structure for Datadog Agent config). Not applicable when using the `delete` operation.
      - `estimated_end_time_unix` integer — Estimated completion time of the deployment as a Unix timestamp (seconds since epoch).
      - `filter_query` string — Query used to filter and select target hosts for the deployment. Uses the Datadog query syntax.
      - `high_level_status` string — Current high-level status of the deployment (for example, "pending", "running", "completed", "failed").
      - `hosts` FleetDeploymentHost[] — Paginated list of hosts in this deployment with their individual statuses. Only included when fetching a single deployment by ID. Use the `limit` and `page` query parameters to navigate through pages. Pagination metadata is included in the response `meta.hosts` field.
        - `error` string — Error message if the deployment failed on this host.
        - `hostname` string — The hostname of the agent.
        - `status` string — Current deployment status for this specific host.
        - `versions` FleetDeploymentHostPackage[] — List of packages and their versions currently installed on this host.
          - `current_version` string — The current version of the package on the host.
          - `initial_version` string — The initial version of the package on the host before the deployment started.
          - `package_name` string — The name of the package.
          - `target_version` string — The target version that the deployment is attempting to install.
      - `packages` FleetDeploymentPackage[] — List of packages to deploy to target hosts. Present only for package upgrade deployments.
        - `name` string, required — The name of the package to deploy.
        - `version` string, required — The target version of the package to deploy.
      - `total_hosts` integer — Total number of hosts targeted by this deployment.
    - `id` string, required — Unique identifier for the deployment.
    - `type` 'deployment', required — The type of deployment resource.
  - `meta` FleetDeploymentResponseMeta — Metadata for a single deployment response, including pagination information for hosts.
    - `hosts` FleetDeploymentHostsPage — Pagination details for the list of hosts in a deployment.
      - `current_page` integer — Current page index (zero-based).
      - `page_size` integer — Number of hosts returned per page.
      - `total_hosts` integer — Total number of hosts in this deployment.
      - `total_pages` integer — Total number of pages available.
