# Search ValidationRules

> Search and list ValidationRule records with filtering, sorting, and pagination.

A **ValidationRule** defines a custom business rule that validates data before it is saved. Rules can be applied to various record types (coworkers, bookings, contracts, visitors, etc.) and enforce custom conditions beyond the standard field validations.

## Authentication

<Note>
  This endpoint requires OAuth2 authentication. Include a valid bearer token in the `Authorization` header.
  The authenticated user must be a full unrestricted administrator or have the **`ValidationRule-List`** role.

## Response

### 200

<ResponseField name="Records" type="ValidationRule[]">
  The list of ValidationRule records matching the query. See the [Get one ValidationRule](/rest-api/sys/get-validationrules-by-id) endpoint for the full list of properties returned for each record.
</ResponseField>

<Warning>
  **Partial records** — The listing endpoint returns a summary representation of each ValidationRule. The following fields are **not populated** in the `Records[]` response: `Formula`, `Description`, `ErrorMessage`.

  To get all fields, fetch the full record using the [Get one ValidationRule](/rest-api/sys/get-validationrules-by-id) endpoint.

  **Important for updates:** When updating a record via `PUT`, always retrieve the full record with a `GET` request first, apply your changes to that complete data, and then send the updated record. Do not use data from a listing response as the base for a `PUT` request, as missing fields may be unintentionally cleared.
