# Source/Medium customization

Littledata enables you to set a **source and medium** to customize how orders get attributed in Google Analytics, based on a set of rules.

You can create custom rules based on:

* **Order sales channel**
* **Order payment gateway**
* **Order tags**

{% hint style="info" %}
If Source / Medium customization is set up, it will override any other attribution for that order session.
{% endhint %}

#### How to use source / medium customization

All the session enrichment settings are located in the **Session enrichment** tab, in the Google Analytics 4 connection settings.

Navigate to the **Session enrichment**, add a rule, fill in the necessary information, and save.

**Custom conditions**

If you wish to add custom channels, tags, or gateways, there will be instructions provided on how to do it once you click `Create custom channel / Create custom gateway`.
{% endhint %}

#### Sales channel

If you want to add a rule for a sales channel/app, you can pick from a list of the most popular sales channels.

Click **Add Custom Value** if you can't find the desired channel in the list, and you can enter an App ID.

For example, if you're using **Recharge** to manage recurring orders, you can set the source/medium `recharge / recurring` for all orders Recharge generates. Littledata would already have tracked recurring purchases, but previously `source` would be Not Set if the subscription was set up before Littledata was installed.

Below is a list of the most popular sales channels and Littledata's recommendations for a custom source/medium:

{% hint style="info" %}
Some of these sources might still fall under the Unassigned default channel. However, adding custom sources for these channels will allow you to have visibility on Source/Medium data that would have otherwise been (not set).
{% endhint %}

#### Order tag

If you want to customize source/medium based on a specific order tag, you can select Order Tag as your criteria.

For example, if you have a custom tag appended to your orders, you can group those orders under a single source/medium in Google Analytics by selecting Order Tag and adding your custom value.

#### Payment gateway

Littledata offers a few standard options for Payment Gateway: **stripe, paypal,** and **klarna.** If none of these is your prefered gateway, you can add a new one by clicking **add payment gateway.**

To find your preferred payment gateway name, navigate to your **Shopify admin**. Go to **Orders** -> **click on an order** that was made via your preferred gateway -> at the end of the **URL**, add `.json` . Your URL should look similar to this:

![add .json to order in shopify admin](/files/748SqmoZ6y39DjEdi8xs)

Then scroll down (or use the find tool from your browser) to search for the gateway. Copy the value from `payment_gateway_names` and paste it in the **Value for payment gateway** field in the Littledata app .
