Onboarding Integration for MBE

Updated: Feb 3, 2026
The Meta Business Extension (FBE) is a click-through popup interface available to approved partners that allows a Facebook user to create and connect business assets (for example, Business Manager, Facebook Page, product catalog, and so on) and set up ads and product shops on different surfaces (Facebook/Instagram).
The onboarding process includes:
  • Creation of the commerce account
  • Asset creation/selection
  • Distribution channel setup
  • Initial inventory synchronization setup
  • Default product collections setup
In this context, onboarding is the creation or selection of assets, commerce account creation, and distribution channel setup.

Before You Start

  • You can set up Facebook Shops without anything at hand, except an eligible Instagram account. This means that any of your sellers can start an MBE flow without an existing catalog, Business Manager, ads account, and so on. Sellers can create all required assets within the MBE flow.
  • To use Instagram Shopping, the account must satisfy our requirements⁠.
  • You can perform your setup via the MBE click-through popup UI. This UI allows sellers to create and select assets and select product and distribution channels.

How it Works

The MBE product contains a click-through installation, FBE management view, and FBE API set.
The MBE flow is outlined in the next steps.

Step 1: Initiate the MBE Click-Through Popup

Initiate the MBE click-through popup to complete the MBE install. Sellers can select assets and select products they want to work with (ads, offsite, Facebook Shops, Instagram, and so on). MBE clicks through a popup redirect seller into your surface after a successful installation.

  "access_token": "<system user token>"
}

    {
      "shop_setup": "SETUP",

            "message": "Your account is not eligible for Facebook Shops at this time.",
            "help_url": "https://www.facebook.com/help/contact/481136396104354"
          }
        ]
      }
    }
  ]
}

Step 5: Monitor Commerce Account Status Changes

Use our commerce webhook to monitor commerce account status changes. For example, to see if sellers enable new channels, make changes to Checkout on Facebook/Instagram to Checkout on another website or vice versa, complete the setup, pass our integrity review, and so on.
To change the commerce setup for sellers, direct them to the MBE management view.
