# Attach a child organization to an enterprise

POST https://api.mezmo.com/v1/enterprise/account
Content-Type: application/json

Attaches an existing organization to an enterprise. The `retention` and `owner` field are optional, and will be defaulted if not specified. To specify which child organization to attach, one of its service keys must be supplied through our typical service key authorization schema; either as basic authorization or through the `servicekey` header.

Reference: https://mezmo.ferndocs.com/api-reference/log-analysis/enterprise/create-org

## Authentication

- `enterprise-servicekey` header (required) — When authorizing against our enterprise endpoints, they expect an enterprise service key instead of a regular organization service key. Some endpoints might expect both an enterprise service key and a regular organization service key.
- `Authorization` header (basic auth, required) — (Deprecated) As an alternative to authenticating with a header value, you can also use basic authentication. To use either `apiKey` or `servicekey` as basic authentication, simply pass the key as the username with no password. For example: ``` curl https://api.logdna.com/v1/config/view -u INSERT_API_KEY: ```
- `servicekey` header (required) — (Deprecated) This key is used for v1 and v2 apis with the exception of ingest. Service keys can be used by placing your service key in the `Authorization` header of your api call. *NOTE* Usage of the service key auth mechanism has been deprecated in favor of IAM Access Tokens. Service keys can no longer be created, but can still be used for v1 and v2 apis while the transition takes place

## Errors

### 400 Bad Request Error

A poorly formatted request returns with a `BadRequest` code.

- `error` (string, optional) — A human-readable description of the error
