Integration Reconnection After Domain Changes

Updated October 22, 2026

What happens to your YouTube, Meta and Google product links when you switch domains

You don't need to disconnect and reconnect the YouTube Product Shelf or Instagram & Facebook Shop apps when you add or switch to a custom domain. Fourthwall manages the product links it sends to YouTube and Meta. If you also use your own Google Merchant Center account, check its feed URL and domain claim.

Which apps and feeds keep working after a domain change​

The YouTube Product Shelf, Instagram & Facebook Shop and your shop's product feed don't depend on a feed URL tied to your old custom domain:

  • YouTube Product Shelf. Fourthwall sends your products to Google through a Merchant Center account it manages. No feed URL is involved.
  • Instagram & Facebook Shop. Meta reads your catalog from a feed URL based on your shop's ID, not its domain.
  • Your shop's product feed. The feed at your shop's fourthwall.com address keeps working after you add a custom domain.

YouTube Product Shelf after a domain change​

The YouTube Product Shelf doesn't need reconnecting when you add or switch to a custom domain. Fourthwall manages the Merchant Center account and product links it uses for YouTube, including verifying your domain with Google.

Your YouTube products can link to your custom domain or to your shop's fourthwall.com address. A fourthwall.com link doesn't mean the connection is broken. If Google won't let Fourthwall claim your new domain, for example because another Merchant Center account already claimed it, your products link to your fourthwall.com address. To release the earlier claim, see Releasing a previous GMC domain claim.

To check your products' review status in YouTube Studio, click Earn in the left menu, open the Shopping tab, and click Organize on the status card.

Instagram & Facebook Shop after a domain change​

The Instagram & Facebook Shop app doesn't need reconnecting when you add or switch to a custom domain. Meta reads your product catalog from a feed URL based on your shop's ID, not its domain. Fourthwall sets Meta to fetch that feed every hour, and each fetch builds product links from your shop's current domain.

Meta Ads​

Meta Ads is a separate app from Instagram & Facebook Shop in Apps. It connects with the Pixel ID and Access Token for the Conversions API from your Meta Events Manager dashboard, not through the Instagram & Facebook Shop connection.

Google Merchant Center after a domain change​

Google Merchant Center works differently for the account Fourthwall manages and for an account you own. Fourthwall manages the Merchant Center account used for the YouTube Product Shelf. You don't have access to that account and don't need to change anything in it.

If you also use your own Merchant Center account, two cases can need your attention:

  • Feed URL. Your shop's product feed at its fourthwall.com address (https://yourshop.fourthwall.com/.well-known/merchant-center/rss.xml) keeps working after you add a custom domain, and its product links use your new domain. If your account fetches the feed from an old custom domain that you've removed from your shop, change the feed URL to your new domain or your fourthwall.com address. See Does Fourthwall provide a Google Product Feed URL?
  • Domain claim. Claiming your new domain in your own account can conflict with the account Fourthwall manages, because they're separate accounts claiming the same website. If that happens, see Releasing a previous GMC domain claim.

Integration reconnection checklist​

After changing your domain, review this checklist to make sure nothing is missed:

  • Domain and DNS: If you have domain connection issues, see Troubleshoot Your Domain and DNS Records
  • YouTube Product Shelf: Nothing to reconnect. Check your products' review status in YouTube Studio under Earn > Shopping
  • Instagram & Facebook Shop: Nothing to reconnect. Fourthwall updates your catalog's product links for you
  • Your own Google Merchant Center account: If it fetches your feed from an old custom domain you've removed, change the feed URL
  • Support email: Added MX records on your support. subdomain so support email is sent from your domain (if your DNS provider allows it)
  • Other integrations: Check any third-party apps in Apps that reference your domain

Frequently Asked Questions​

Does my support email change automatically?​

Only once your domain's support email records are in place. With a custom domain, Fourthwall sends customer support emails from a support. subdomain of your domain (for example, contact@support.yourcustomdomain.com), which needs MX records on that subdomain. If your DNS provider can't add MX records on a subdomain, support emails keep working but are sent from a Fourthwall address. See Why can't I set MX records?

How long does DNS propagation take?​

DNS changes can take up to 24 hours to propagate, though most updates complete within a few hours. During this time, some visitors may still see the old domain. For DNS troubleshooting help, see Troubleshoot Your Domain and DNS Records.

Do I need to update my Twitch or Discord integrations?​

Twitch and Discord integrations connect through your Fourthwall account, not your domain. They don't need reconnection after a domain change. If you notice issues, disconnect and reconnect the integration in Apps.

Fourthwall manages the product links it sends to YouTube and Meta, so you don't need to reconnect anything. YouTube products can link to your custom domain or your shop's fourthwall.com address, and a fourthwall.com link doesn't mean the connection is broken. If your products still link to your old domain, contact us at support@fourthwall.com with your shop URL.

If you have any questions, do not hesitate to contact us at support@fourthwall.com.
