用户体验指南
您可以就关联 Google Ads 帐号之目的提供更多信息。您可以参考下面的示例，了解这一过程可能是什么样子。
用户可能对 Google Ads 帐号拥有不同级别的访问权。由于用户只能关联他们拥有修改权限的 Google Ads 帐号，因此请通知用户访问权限出现问题的情况。以下是一个示例。
现有 Google Ads 帐号可能存在多个问题。如果某个 Google Ads 帐号被中止，请不要将其添加到用户可选择的列表中。
对于现有 Google Ads 帐号，应会显示以下问题：需要进行两步验证，需要更新结算信息，并且转化跟踪已就绪。下面概述了在选择 Google Ads 帐号后应显示的所有消息（如果适用）。如需了解详情，请参阅 4.5 错误处理部分。

It also streamlines the review process, and reduces the number of times\nyou need to go through the authentication process to manage your accounts using\nthe API. For details, see\n[Link your Merchant Center and Google Ads accounts](https://support.google.com/google-ads/answer/6159060).\n\nLink each Merchant Center client account with the merchant's Google Ads\nadvertiser account. You can also link multiple Google Ads accounts to a single\nMerchant Center account, and a single Google Ads account can be linked to\nmultiple Merchant Center accounts, but this is not recommended as part of the\nFoundational Pillar.\n\n### UX guidance\n\n*** ** * ** ***\n\nYou may provide more information about the purpose of connecting a Google Ads\naccount. You can find below an example of how this might look.\n\nA user may have different levels of access to a Google Ads account. Because the\nuser can only connect Google Ads accounts for which they have edit access,\ninform them about cases when access is an issue. An example of how this might\nlook is below.\n\nMultiple issues may be associated with existing Google Ads accounts. If a Google\nAds account is suspended, don't include it in the list a user may choose from.\nThe following issues should be displayed for existing Google Ads accounts:\n2-Step Verification required, billing information needs to be updated and\nconversion tracking already in place. Below is an overview of all the messages\nwhich should be surfaced if applicable after selecting a Google Ads account.\nFor more details, see section [*4.5 Error handling*](/merchant/storebuilder/online/sections/4_5_error_handling).\n\n### Tech Guidance\n\n*** ** * ** ***\n\nTo link a merchant's Google Ads advertiser account to the merchant's Merchant\nCenter client account, request a link from the Merchant Center. You can ask your\nmerchant to do this manually in Merchant Center, or do it automatically using\nthe Content API for Shopping. Note that:\n\n- You need to be a Merchant Center user with the role set\"Admin\" to initiate\n the linking request.\n\n- You need to have [*admin access*](https://support.google.com/google-ads/answer/9978556) to your Google Ads account to link\n Google Ads and Merchant Center accounts.\n\nFollow these two steps to link a Google Ads account to a Merchant Center\naccount:\n\n1. [Send a link request from Merchant Center](https://developers.google.com/google-ads/shopping/full-automation/articles/t15#automatic_steps) to Google Ads, using the\n Content API.\n\n2. [Accept the link through Google Ads](https://developers.google.com/google-ads/shopping/full-automation/articles/t16#automatic_steps), using the Ads API.\n\nWe recommend implementing retry logic for both the sending and accepting of the\nlink request in the event that either one of them fails during this process.\nThat is because a link between Merchant Center and Google Ads is required in the\nfuture API call to create a Performance Max for Retail campaign, and an error of\nresource not found may occur if the link was not established.\n| **Notes:**\n|\n| - The merchant receives a confirmation email from Google once you link the account on its behalf.\n| - When displaying the list of existing Google Ads accounts, you should filter out Google Ads manager accounts, as they cannot be linked to Merchant Center accounts."]]
