Multi Client account and LFP account setup


A multi-client account (MCA) is an accounts container that simplifies the API authentication process, new merchants account creation, day-to-day management and reporting. Since an MCA has a top-level-account to sub-accounts structure, an MCA administrator can have access to all sub-account nested under the MCA. API calls are also authenticated through the MCA account for all the relative sub-accounts and for all API methods available.

  1. Create a Merchant Center account at the Merchant Center sign up page or use an existing one if it was already created.
  2. When creating a Merchant Center account we recommend making a Google account that's unique to your business instead of using your personal account. Because this account is for your business, you may want to consider its name carefully.
  3. Next, file a request with the support team to convert the account to a "Multi Client Account" (MCA), also known as an advanced account, in the Merchant Center advanced settings.
  4. Once the MCA is created, create a new sub-account in the partner's name. This account is exclusively used to submit inventory, sales or store data for merchants. This account will be referred to as an "Lfp provider account" throughout this guide.

Quota Management


For Merchant Center sub-accounts created under your MCA, these merchants are subject to your MCA's quota. These are quotas such as sub accounts, offers, and feeds. For offer quotas increases, it is imperative to ensure you keep your MCA's total product disapproval to a range 10-20% to avoid any issues with future increases. Once your MCA hits the max quota of your account, you are not able to add more offers or sub-accounts to your account.

For quota increase requests, file a request in the Quota Request form. We recommend keeping an eye on your quota as it takes time to process.


In order to send data as a Local Feed Partnership Provider, your retailers' Merchant Center accounts need to be linked to the LFP provider account. To achieve full deployment Google recommends using the API as it offers many advantages in scalability and automating common tasks.

Alternatively, the Merchant Center UI can be used in the earlier version of Merchant Center

Linking the merchant account to the Local Feed Provider can be achieved using liasettings.setposdataprovider.
