When you apply an\ninventory filter to a campaign, only offers that match the filter are\nadvertised. You can create an inventory filter in the [Google Ads UI](https://ads.google.com/).\n\nThe steps in this section use **Custom label** as an example. You can also do\nthis with other supported feed attributes, like Product type, Brand, or\nGoogle product category.\n| **Key Term:** In the Google Ads API, inventory filters are referred to as *listing\n| scopes*.\n\nFilters follow `AND` logic. You only see results that match all of the\ncriteria in your filter.\n\nManual steps\n------------\n\nHere's an example of the manual steps, using the attribute **Custom label**:\n\n1. [Link Merchant Center to Google Ads](/google-ads/shopping/full-automation/articles/t15).\n2. Sign in to the [Google Ads account](https://ads.google.com/).\n3. Click an existing campaign that uses your Merchant Center products, or [create a new one](/google-ads/shopping/full-automation/articles/t18).\n4. Click **Settings** in the left sidebar.\n5. Expand the **Additional settings** dropdown menu.\n6. Click **Inventory filter**.\n7. In the boxes shown:\n 1. Select **Custom label 0** . **Custom label 0-4** are supported.\n 2. Enter a value for the custom label.\n8. To filter by multiple values, click **AND** and repeat the preceding step.\n\nAutomatic steps\n---------------\n\nYou can only apply one listing scope per campaign. Each listing scope can\ninclude multiple product filters.\n\nHere's an example of the automatic steps, using `product_custom_attribute` as an\nexample:\n\n1. Make sure you've successfully created a campaign and have a campaign ID.\n2. Call [`MutateCampaignCriteriaRequest`](/google-ads/api/reference/rpc/latest/MutateCampaignCriteriaRequest) as follows:\n 1. Set the `campaign_criterion_operation` to `create`.\n 2. Set the `product_custom_attribute.index` to `0` (`0`-`4` are supported).\n 3. Set the `product_custom_attribute.value` to your desired value for the custom label.\n 4. Set the `campaign` field to the `resource_name` of the `campaign_criterion` you created in the preceding step.\n\n[Custom label](https://support.google.com/merchants/answer/6324473) values can be 1 to 100 characters in length, and there can\nbe up to 1,000 unique values account-wide for each custom label attribute (up to\n5,000 labels total).\n\nSee the [Google Ads Shopping example](https://github.com/googleads/google-ads-python/blob/main/examples/shopping_ads/add_listing_scope.py) for examples of other kinds of inventory\nfilters and more detail."]]
