There may be cases where you need to index some entity data to Klevu where a Magento attribute does not represent that data.

:::hint{type="info"}
If the data needs to be searchable and/or filterable then creating a static attribute is the recommended way to handle that. However, if the data is only to be used on the frontend, then sending it in `additionalDataToReturn` is a simpler approach and a static attribute would not be required.
:::

e.g. For a product you want to send the following data in the entity payload

```json
{
    "name": "Product Name",
    "sku": "SKU-101",
    "some_attribute": "This is not a Magento attribute, but some third-party data"
}
```

Where `some_attribute` is not a Magento attribute but is data pulled from some third-party source.
With the Klevu JSON API, we **must** register `some_attribute` as an attribute before sending data for that attribute in the entity payload.

Klevu provides `StaticAttributeProvider` to accomplish this. Called “static” as they are hardcoded in the `di.xml` and cannot be updated via the admin or the database.

We add attributes to `StaticAttributeProvider` by injecting the required attribute(s) into the attributes argument via `di.xml`.  
e.g.

:::CodeblockTabs
Vendor/Module/etc/di.xml

```xml
<type name="Klevu\IndexingProducts\Service\Provider\StaticAttributeProvider">
    <arguments>
        <argument name="attributes" xsi:type="array">
            <item name="some_attribute" xsi:type="array">
                <item name="attribute_id" xsi:type="number">100001</item> <!-- required -->
                <item name="attribute_code" xsi:type="string">some_attribute</item> <!-- required -->
                <item name="is_searchable" xsi:type="boolean">true</item> <!-- optional: default = false -->
                <item name="is_filterable" xsi:type="boolean">false</item> <!-- optional: default = false -->
                <item name="is_returnable" xsi:type="boolean">true</item> <!-- optional: default = false -->
                <item name="default_label" xsi:type="string">Some Attribute</item> <!-- optional: default = attribute_code with underscores removed and uppercase first letter -->
                <item name="labels" xsi:type="array"> <!-- optional: item names are store ids -->
                    <item name="1" xsi:type="string">Store Label</item>
                    <item name="2" xsi:type="string">Étiquette du magasin</item>
                    <item name="3" xsi:type="string">Store-Etikett</item>
                </item>
                <!-- The following are used to determine what attribute type is created in Klevu -->
                <!-- Klevu attribute types are STRING, NUMBER, MULTIVALUE -->
                <!-- If none of these are set the default attribute type is STRING -->
                <item name="frontend_input" xsi:type="string">select</item> <!-- optional -->
                <item name="backend_type" xsi:type="string">int</item> <!-- optional -->
                <item name="source_model" xsi:type="string">Vendor\Module\Model\Source\SomeAttributeSource</item> <!-- optional -->
                <item name="is_html_allowed_on_front" xsi:type="number">1</item> <!-- optional -->
                <item name="is_global" xsi:type="number">1</item> <!-- optional -->
            </item>
        </argument>
    </arguments>
</type>
```

We can do the same for Categories injecting into `Klevu\IndexingCategories\Service\Provider\StaticAttributeProvider`
