# Linking an Incoming Cross-sale to an Outgoing Cross-sale

*Article Topics:* [*Cross Sales*](/getting-started/common-topics/cross-sales.md)*,* [*Up Sales*](/getting-started/common-topics/up-sales.md)*,* [*Programs*](/getting-started/common-topics/programs.md)*,* [*Affiliate*](/getting-started/common-topics/affiliates.md)

{% hint style="info" %}
**Please Note:** This article uses a cross-sale as an example but the process is similar for linking incoming up-sales to outgoing up-sales. 
{% endhint %}

Now that both Outgoing Sales and Incoming Sales have been covered, you will need to know how to link the two. NATS allows you to perform a cross-sale or an up-sale between two sites by providing a tool that generates a **reference code** using data from a specific affiliate, campaign, program, and cross-sale. You can then use this reference code to link the incoming and outgoing cross-sales together. 

In short, reference codes are generated from the **Incoming cross-sale** that corresponds to each **Outgoing cross-sale.** 

You can access this tool by adding "**internal.php?page=xsells**" to your [Linkdomain](/using-nats/nats-admin-features/linkdomain.md) URL on your NATS installation.

## Linking a Cross-sale

To link a cross-sale between two of your NATS Sites,

1\) [Create a new Incoming Cross Sale](/nats-admin/cross-up-sales/common-questions/how-to-add-and-delete-a-cross-or-up-sale.md)&#x20;

2\) Navigate to the "**<https://domain/internal.php?page=xsells>**" page to view the Ref Code.&#x20;

* Please note, you will need to be [overriding as the affiliate](/nats-admin/affiliates/further-reading/affiliate-override.md) account that will receive credit for the cross sale by default.

3\) Copy the Ref Code associated with your Cross Sale.&#x20;

4\) [Create a new Outgoing Cross Sale](/nats-admin/cross-up-sales/common-questions/how-to-add-and-delete-a-cross-or-up-sale.md)&#x20;

5\) Insert the Ref Code into the Biller Details section of your Outgoing Cross Sale.&#x20;

This will create the link between your Outgoing Cross Sale and Incoming Cross Sale. &#x20;
