# Update an organization

`PATCH /v1/organizations/{org_id}` · permission `organizations:write`

Updates an organization with a JSON merge patch (RFC 7396, `Content-Type: application/merge-patch+json`). Fields that are not sent do not change; a patch that changes nothing does not change the version. `name` and `slug` cannot be cleared.

## Request

| Field | Type | Required | Description |
|---|---|---|---|
| `org_id` | path | yes | Organization ID (`org_…`). |
| `If-Match` | header | yes | Required. The `ETag` of the last read (`"<version>"`). |
| `name` | string | no | Display name, 1-256 characters, no control characters. |
| `slug` | string | no | New slug (same format). Can change once every 30 days; the old slug stays reserved for 90 days. |
| `external_id` | string \| null | no | Your own identifier, up to 255 characters; unique in the environment. `null` clears it. |
| `metadata` | object \| null | no | Merged into the current object (RFC 7396): a member set to `null` is removed; `null` for the whole field resets it to `{}`. |
| `brand_color` | string \| null | no | Brand color `#RRGGBB`; stored in upper case. `null` clears it. |
| `max_memberships` | integer \| null | no | Membership cap, at least 1; `null` means unlimited. |
| `default_zoneinfo` | string \| null | no | Default IANA time zone (for example `Europe/Istanbul`), used for sign-up, invitation, JIT SSO and SCIM in the organization context when the browser or IdP supplies none. `null` clears it (the environment default applies). |
