# Batch Retrieve Inventory Changes

Returns historical physical counts and adjustments based on the
provided filter criteria.

Results are paginated and sorted in ascending order according their
`occurred_at` timestamp (oldest first).

BatchRetrieveInventoryChanges is a catch-all query endpoint for queries
that cannot be handled by other, simpler endpoints.

```php
function batchRetrieveInventoryChanges(BatchRetrieveInventoryChangesRequest $body): ApiResponse
```

## Parameters

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

## Response Type

[`BatchRetrieveInventoryChangesResponse`](../../doc/models/batch-retrieve-inventory-changes-response.md)

```php
$body = new Models\BatchRetrieveInventoryChangesRequest();
$body->setCatalogObjectIds(['W62UWFY35CWMYGVWK6TWJDNI']);
$body->setLocationIds(['C6W5YS5QM06F5']);
$body->setTypes([Models\InventoryChangeType::PHYSICAL_COUNT]);

# Batch Retrieve Inventory Counts

Returns current counts for the provided
[CatalogObject](../../doc/models/catalog-object.md)s at the requested
[Location](../../doc/models/location.md)s.

Results are paginated and sorted in descending order according to their
`calculated_at` timestamp (newest first).

When `updated_after` is specified, only counts that have changed since that
time (based on the server timestamp for the most recent change) are
returned. This allows clients to perform a "sync" operation, for example
in response to receiving a Webhook notification.

# Retrieve Inventory Changes

**This endpoint is deprecated.**

Returns a set of physical counts and inventory adjustments for the
provided [CatalogObject](../../doc/models/catalog-object.md) at the requested
[Location](../../doc/models/location.md)s.

You can achieve the same result by calling [BatchRetrieveInventoryChanges](../../doc/apis/inventory.md#batch-retrieve-inventory-changes)
and having the `catalog_object_ids` list contain a single element of the `CatalogObject` ID.

Results are paginated and sorted in descending order according to their
`occurred_at` timestamp (newest first).

There are no limits on how far back the caller can page. This endpoint can be
used to display recent changes for a specific item. For more
sophisticated queries, use a batch endpoint.

```php
function retrieveInventoryChanges(
    string $catalogObjectId,
    ?string $locationIds = null,
    ?string $cursor = null
): ApiResponse
```

## Parameters

| Parameter | Type | Tags | Description |
