# Four51

Order Desk can connect to your [Four51](https://public.four51.com/) shopping cart and download your orders. This guide explains how to setup and use the Four51 integration.

### Setup

To begin, click on **Manage Integrations** from the left sidebar in Order Desk. Under the **Shopping Carts** tab, find and enable Four51.

#### Receive Orders

Enable or disable order import from Four51 into Order Desk. For orders to import, you must put the provided Webhook URL into your Four51 account.

#### Sync Tracking Numbers

If enabled, shipment details will be passed back to the original order in Four51 as they are added to Order Desk.

#### Folder for New Orders

Choose the folder where new orders should be placed as they come in from Four51. You can use the default New folder, or create your own custom folder from your [Store Settings](/start-here/getting-started-series/quick-start-overview.md#working-with-folders).

#### SKU Source

Choose which Four 51 item field should be used as the SKU. You can select either the **Supplier Part Auxiliary ID** or **Supplier Part ID**.

#### Webhook URL

If you skipped the first step in the setup section, you will need to set this webhook URL in your Four51 account for Order Desk to download your orders.

#### Order Prefix

If you would like to set a prefix on all orders brought into Order Desk from Four51, set that here.

# 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://help.orderdesk.com/integration-setup-guides/sales-channels/four51.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.
