# Update URL mapping configuration file

The Azure URL mapping function uses a configuration file called *url-mapping-config.json* that is stored inside a Mappings container in the storage account that is created within Azure.

To update the URL mapping configuration file:

1. Log into your [Microsoft Azure](https://portal.azure.com/#home) portal page.
2. Open the storage account created above for the URL mapping (that is *stimageproxydev001*).
3. In the left pane, click the Storage browser (preview).
4. Click **Blob containers**.
5. Click **mappings** in the right pane containers.
6. Next to the url-mapping-config.json file. click **...** to view and edit the file. The JSON file contains the following settings.

    ```json
    {
     "ProductUrl": "/Products/{ProductNumber}_000_{SequenceNumber}.png",
     "ProductVariantUrl": "/Products/{ProductNumber} ^ {Style} ^ {Size} ^ {Color} ^_000_{SequenceNumber}.png",
     "ProductVariantWithConfigurationUrl": "/Products/{ProductNumber} ^ {Configuration}_000_{SequenceNumber}.png",
     "ContentHubGraphQLProductFieldToQuery": "ProductNumber"
    }
    ```

7. As required, update the Product URLs regular expressions or change the target field to query for a Product in Sitecore Content Hub.
8. Click **Save** and then click X to close the file.

> [!note]
> The **ContentHubGraphQLProductFieldToQuery** field value must match the exact *M.PCM.Product* field name, must be a string field type, and must have the **Include in content** switch set to active (On) in Content Hub. The only exception is when you want to use an Identifier field.
