# Update an organization domain

`PATCH /v1/organization-domains/{domain_id}` · permission `organization-domains:write`

Updates the domain's capture and SSO routing settings with a JSON merge patch (RFC 7396, `Content-Type: application/merge-patch+json`). Both can only be turned on for a `verified` domain. A patch that changes nothing does not change the version.

## Request

| Field | Type | Required | Description |
|---|---|---|---|
| `domain_id` | path | yes | Organization domain ID (`odm_…`). |
| `If-Match` | header | no | Optional. When sent it must match the `ETag` of the last read (`"<version>"`). |
| `capture_mode` | string | no | `off`, `suggest` or `auto_join`: what happens when a user with an email address on this domain signs in. |
| `sso_routing_enabled` | boolean | no | Route sign-ins with this domain to the organization's SSO connection. |

Request body:

```json
{
  "capture_mode": "suggest",
  "sso_routing_enabled": true
}
```

## Response

`200 OK` with the updated domain and its new `ETag`.
