The local inventory service within the Merchant API allows creating and updating local inventory instances for physical store locations, linked to existing product resources. Prerequisites include setting up a Business Profile, linking it to Merchant Center, verifying the business, and enrolling in a local program. The service supports `localinventory.insert` to create a single instance and `localinventory.custombatch` for multiple instances and only `storeCode` and `productId` are required for all requests.\n"],null,["# Local inventory service\n\nThe local inventory service allows you to create and update instances of the\n[local inventory resource](/shopping-content/reference/rest/v2.1/localinventory#resource:-localinventory),\nwhich contain fields that can have different values\nfor different physical store locations. Each local inventory instance is a child\nof an existing [product resource](/shopping-content/reference/rest/v2.1/products#resource:-product),\nand inherits the product data fields from the\nparent resource. For example, you might have a product that has a different\nprice and quantity in different stores, but shares an ID, description, and other\nproduct data across all stores. Local inventory data is used for the\n[Local surfaces across Google](//support.google.com/merchants/answer/9825611)\nand [Local Inventory Ads](//support.google.com/merchants/answer/3057972)\nprograms.\n\nThis guide explains what you need before you start using the local inventory\nservice, describes the available fields and methods, and provides an example of\na service request.\n| **Note:** In v2.1 of the Content API, the local inventory service and supplemental feeds replace the inventory service in v2. To perform partial updates to non-local product data with API v2.1, use [supplemental feeds](/shopping-content/guides/products/supplemental-feeds). To make supplemental local product updates, use the [`localinventory`\n| service](/shopping-content/guides/products/local-inventory).\n\nPrerequisites\n-------------\n\n- In order to use the local inventory service, you must [create a Business Profile](//support.google.com/business/answer/6300717), [link your Business Profile to your Merchant Center account](/shopping-content/guides/how-tos/lia/link-gmb), [verify your business](//support.google.com/business/answer/6300716), and [set up your Business Profile store codes](//support.google.com/business/answer/4542487).\n- Your Merchant Center account must be enrolled in a local program: either\n **Local surfaces across Google** or **Local inventory ads** . For more\n information about using local inventory ads via the Content API, see\n [Get Started with Local Inventory Ads](/shopping-content/guides/how-tos/lia/get-started).\n\n | **Note:** If your Merchant Center account is not enrolled in a local program, setting a product's `channel` field to `local`, via the [`Products.insert`](/shopping-content/reference/rest/v2.1/products/insert) method, results in the error: \"\u003cvar translate=\"no\"\u003echannel\u003c/var\u003e Invalid channel: local\".\n- The local inventory service creates local inventory instances for existing\n local products You must first create local products, using either the Content\n API [products](/shopping-content/reference/rest/v2.1/products) service or\n Merchant Center [datafeeds](//support.google.com/merchants/answer/7439882), by\n setting the `channel` field to `local`. You can then use the local inventory\n service to create local inventory instances for each Business Profile\n `storecode` where the product is sold.\n\nFields\n------\n\nEach local inventory instance contains a set of fields that is associated with a\nspecific store location via the `storeCode` field (which you define in your\nBusiness Profile). Only\n[`storecode`](/shopping-content/reference/rest/v2.1/localinventory#LocalInventory.FIELDS.store_code)\nand\n[`productId`](/shopping-content/reference/rest/v2.1/products#Product.FIELDS.id)\nare required for all requests. All other fields are optional:\n\n- Required for all requests: `storeCode`, `productId` (in URL)\n- Optional: `quantity`, `price`, `salePrice`, `salePriceEffectiveDate`, `availability`, `pickupMethod`, `pickupSla`, `instoreProductLocation`\n\nFor a complete list of local inventory fields and their descriptions, see the\n[localinventory](/shopping-content/reference/rest/v2.1/localinventory) reference\npage.\n\nMethods\n-------\n\nThe local inventory service only includes two methods:\n\n### localinventory.insert\n\n[`localinventory.insert`](/shopping-content/reference/rest/v2.1/localinventory/insert)\nallows you to create a local inventory instance for a single local product.\n\nThis example demonstrates how to use the local inventory service to\n[create an in-store sale](//support.google.com/merchants/answer/9017019) from\nFebruary 24th, 2021 at 1:00 pm (GMT-8) until February 28th, 2021 at 3:30pm\n(GMT-8). The request also updates the quantity available for the local inventory\ninstance. Unlike\n[supplemental feeds](/shopping-content/guides/products/supplemental-feeds)\nfor non-local product data, fields that are not included in the body of the\nrequest are overwritten by this call: \n\n POST https://shoppingcontent.googleapis.com/content/v2.1/\u003cvar translate=\"no\"\u003emerchantId\u003c/var\u003e/products/\u003cvar translate=\"no\"\u003eproductId\u003c/var\u003e/localinventory\n\n {\n \"storeCode\": \"1235\",\n \"salePrice\": {\n \"value\": \"100.00\",\n \"currency\": \"USD\"\n },\n \"salePriceEffectiveDate\": \"2021-02-24T13:00-0800/2021-02-28T15:30-0800\",\n \"quantity\": 200,\n }\n\n### localinventory.custombatch\n\n[`localinventory.custombatch`](/shopping-content/reference/rest/v2.1/localinventory/custombatch)\nallows you to create multiple local inventory instances for a single\nlocal product in multiple stores, or create local inventory instances for\nmultiple local products.\n| **Note:** It is not possible to retrieve, list, or delete local inventory instances. To view local inventory data in Merchant Center, select a local product in the **All products** page and then expand the **Local inventory** section. The table displays the local inventory data for each store code."]]
