# Update user

PATCH https://api.getzep.com/api/v4/users/{user_uuid}
Content-Type: application/json

Reference: https://help.getzep.com/sdk-reference/user/update

## Authentication

- `Authorization` header (required) (prefixed with ` Api-Key  `) — Type "Api-Key" followed by a space and the project API key.

## Request

### Path parameters

- `user_uuid` (string, required) — User UUID

### Body (application/json)

This endpoint expects a v4.PatchUserRequest.

- `disable_default_ontology` (boolean, optional) — When true, disables the default ontology for the user's graph.
- `email` (string, optional) — The email address of the user.
- `first_name` (string, optional) — The user's first name.
- `last_name` (string, optional) — The user's last name.
- `metadata` (V4PatchUserRequestMetadata, optional, nullable) — Metadata to merge onto the user; a key set to null is removed.
- `time_zone` (string, optional) — The user's IANA time zone.

## Response

### 200

OK

- `created_at` (string, optional) — The time the user was created.
- `disable_default_ontology` (boolean, optional) — When true, disables the use of the default fallback ontology for the user's graph.
- `email` (string, optional) — The email address of the user.
- `first_name` (string, optional) — The first name of the user.
- `graph_uuid` (string, optional) — The unique identifier of the user's graph, populated when the user is created.
- `last_name` (string, optional) — The last name of the user.
- `metadata` (map from string to any, optional) — Arbitrary key-value metadata attached to the user.
- `time_zone` (string, optional) — The user's IANA time zone, used to localize dates in generated context.
- `user_id` (string, optional) — An optional external identity identifier, such as an identity-provider subject claim. Zep uses it to match an identity-provider sign-in to this user. It is not an address; use uuid to address the user in v4. It is unique within the project, can contain at most 500 characters, and cannot be changed after creation. v4 sets it on create; v3 users keep their existing value.
- `uuid` (string, optional) — The unique identifier of the user.
