# Batch Update Inventory

It is used to batch update the inventory by using request format.

| Field          | Data Type | Default Value | Description                                                                                                                                                                          |
| -------------- | --------- | ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `ItemNumber`   | string    | NA            | SKU number.                                                                                                                                                                          |
| `DeltaQty`     | decimal   | 0             | Instead of sending a new and old value for inventory an adjustment value can be sent.                                                                                                |
| `OldQty`       | decimal   | 0             | The original stock level that the client believes the product variant has. This should be sent to avoid a race condition when the item being adjusted is simultaneously sold online. |
| `NewQty`       | decimal   | 0             | The number of items in stock for this product variant.                                                                                                                               |
| `LocationDisp` | string    | NA            | Warehouse 3PL location (Provided by the client).                                                                                                                                     |

Note: If New/Old Qty and Delta Qty are both provided then New/Old Qty will take priority and Delta Qty will be ignored.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.xorosoft.com/developers-api/inventory-management/batch-update-inventory.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
