Website verification allows us to validate a merchant's ownership of the website. Claiming allows us to create an exclusive link between the website and Merchant Center account. [Learn more why and how this process works](https://support.google.com/merchants/answer/176793).\n\n### UX Guidance\n\n*** ** * ** ***\n\nSurface error message if the domain is connected to another Merchant Center account. Allow merchants to transfer domain but inform merchants about the consequence of transferring domain upfront.\n\n### Tech Guidance\n\n*** ** * ** ***\n\nWe recommend the ability to verify and claim their website within your integration using our [Site Verification](https://developers.google.com/site-verification/v1/webResource) and [Content API](https://developers.google.com/shopping-content/reference/rest/v2.1/accounts/claimwebsite).\n\n#### Initially verifying and claiming a website\n\nThe merchant's website should currently not be linked to any Merchant Center account. Ensure that it is the same Google account which initiates verification and performs claiming ([Learn more](https://support.google.com/merchants/answer/7527436)). All new merchants center accounts and existing merchant center accounts need to follow the steps below:\n\n1. **Check if the website is claimed already:** The [account statuses](https://developers.google.com/shopping-content/reference/rest/v2.1/accountstatuses) website Claimed property will equal TRUE if the website is claimed or the account is exempted from the claim requirement. If not, move forward with verifying and claiming.\n\n2. **Verify:** use the [insert method](https://developers.google.com/site-verification/v1/webResource/insert) to verify the website ([Learn more](https://developers.google.com/site-verification/v1/webResource)). Make sure to first place the authenticated user's verification token on their website or domain.\n\n3. **Claim:** use [accounts.claim](https://developers.google.com/shopping-content/reference/rest/v2.1/accounts/claimwebsite) to claim the merchant's website\n\nIn some cases, the website could be already claimed by another MC account. See the section below if the website is claimed by another GMC.\n\n#### Ongoing verifying and claiming a website\n\nIn August 2022, we launched a new feature that allows merchants 60 days to keep their claim if they lose their verification. Merchants lose their verification for different reasons. Most of them removed the identifying meta tag from their sites. (See [More details on potential root causes](https://support.google.com/merchants/answer/7527436)).\n\nIn a case where a merchant loses their verification, they will need to reverify their website and claim again (if it's lost). Please see the technical steps below to check the verification status and attempt a reverification.\n\n- To find if a merchant has the verification for their site, you should call the site verification API ([list](https://developers.google.com/site-verification/v1/webResource/list)) for that user and check that the URL is in the returned list.\n\n| **Note:** do not use Content API for this, since it only returns [claim status](https://developers.google.com/shopping-content/reference/rest/v2.1/accountstatuses#AccountStatus) with \"websiteClaimed\", not verification status.\n\n- If a given merchant requires verification, you could re-verify the site by calling [getToken](https://developers.google.com/site-verification/v1/webResource/getToken) to get the tag to add on the site, then inject that on the site and finally call [insert](https://developers.google.com/site-verification/v1/webResource/insert) to trigger a verification. Consider asking merchants permission to do this, but this is your decision.\n\n- Claim (if needed): use [accounts.claim](https://developers.google.com/shopping-content/reference/rest/v2.1/accounts/claimwebsite) to claim the merchant's website\n\nWe recommend building an automated functionality that checks the verification status of a merchant, reverify and claim the merchants' website if needed.\n\n#### Website is already claimed by another GMC account\n\nIt can happen that a website is claimed by an unknown MC account which prevents you from claiming the website. In this case we recommend:\n\n- Ask your mechant to manually overwrite the claim in Merchant Center\n\n- If the above is not possible, reach out to your Google POC\n\n| **Tip:** If your Merchant Center accounts use the same top domain and their landing pages are subdomains of the top domain, you can use [accounts.custombatch](https://developers.google.com/shopping-content/reference/rest/v2.1/accounts/custombatch#authorization-scopes) to retrieve, claim, insert, update, and delete multiple accounts in a single request.\n| **Warning:** The claiming Merchant Center account may have a claim at a higher level, which covers uses at all lower levels, and so lower levels cannot be separately claimed. For example, a Merchant Center claiming http://example.com means that another Merchant Center cannot claim http://merchant.example.com, and a claim of http://marketplace.example.com means that http://marketplace.example.com/store cannot be separately claimed.\n\nHTTP request: [accounts.claimwebsite](https://developers.google.com/shopping-content/reference/rest/v2.1/accounts/claimwebsite) \n\n POST https://shoppingcontent.googleapis.com/content/v2.1/{merchantId}/accounts/{accountId}/claimwebsite\n\nResponse: [AccountsClaimWebsiteResponse](https://googleapis.dev/java/google-api-services-content/latest/com/google/api/services/content/model/AccountsClaimWebsiteResponse.html)"]]
