profiles can take closer to one minute or longer, especially during network incidents and outages.

```php
function listCustomers(
    ?string $cursor = null,
    ?int $limit = null,
    ?string $sortField = null,
    ?string $sortOrder = null,
    ?bool $count = false
): ApiResponse
```

## Parameters

| `limit` | `?int` | Query, Optional | The maximum number of results to return in a single page. This limit is advisory. The response might contain more or fewer results.<br>If the specified limit is less than 1 or greater than 100, Square returns a `400 VALUE_TOO_LOW` or `400 VALUE_TOO_HIGH` error. The default value is 100.<br><br>For more information, see [Pagination](https://developer.squareup.com/docs/build-basics/common-api-patterns/pagination). |
