# List Customers

Lists customer profiles associated with a Square account.

Under normal operating conditions, newly created or updated customer profiles become available
for the listing operation in well under 30 seconds. Occasionally, propagation of the new or updated
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
): ApiResponse
```

## Parameters

| Parameter | Type | Tags | Description |
|  --- | --- | --- | --- |
| `cursor` | `?string` | Query, Optional | A pagination cursor returned by a previous call to this endpoint.<br>Provide this cursor to retrieve the next set of results for your original query.<br><br>For more information, see [Pagination](https://developer.squareup.com/docs/build-basics/common-api-patterns/pagination). |
| `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). |

| Parameter | Type | Tags | Description |
|  --- | --- | --- | --- |
| `body` | [`SearchCustomersRequest`](../../doc/models/search-customers-request.md) | Body, Required | An object containing the fields to POST for the request.<br><br>See the corresponding object definition for field details. |

# Delete Customer

Deletes a customer profile from a business. This operation also unlinks any associated cards on file.

As a best practice, you should include the `version` field in the request to enable [optimistic concurrency](https://developer.squareup.com/docs/working-with-apis/optimistic-concurrency) control. The value must be set to the current version of the customer profile.

To delete a customer profile that was created by merging existing profiles, you must use the ID of the newly created profile.

```php
function deleteCustomer(string $customerId, ?int $version = null): ApiResponse
```
