# Create or update custom properties for an enterprise

`PATCH /enterprises/{enterprise}/properties/schema`

Creates new or updates existing custom properties defined for an enterprise in a batch.

If the property already exists, the existing property will be replaced with the new values.
Missing optional values will fall back to default values, previous values will be overwritten.
E.g. if a property exists with `values_editable_by: org_and_repo_actors` and it's updated without specifying `values_editable_by`, it will be updated to default value `org_actors`.

To use this endpoint, the authenticated user must be an administrator for the enterprise.
