- `PUT` `/platform/configuration/networking/deployment_domain_name`

- [Basic auth](/elastic/docs-builder/docs/4371/api/doc/cloud-enterprise/v4/authentication#basicauth)
- [Api key auth](/elastic/docs-builder/docs/4371/api/doc/cloud-enterprise/v4/authentication#apikey)

## Description

Saves the default Deployment Domain Name configuration value.

## Query String Parameters

- `version` (string)
  If specified, then checks for conflicts against the version stored in the persistent store (returned in 'x-cloud-resource-version' of the GET request). If not specified, will unconditionally upsert.
- `skip_cascading_operations` (boolean · default: false)
  Whether or not to skip cascading operations, such as re-provisioning the Security Deployment.

## Request Body

`application/json`

Data containing the Deployment Domain Name to set

- `value` (string) — required
  The domain name for all deployments. The hostname of an application in a deployment is constructed from the application ID and the domain name (for example, 1234567890.example.com).

## Responses

#### `200`
