Platform Integrations (TikTok, Instagram, YouTube)

Updated October 26, 2026

Connect your Fourthwall shop to social platforms so your products show up where your audience already is

Fourthwall integrates with TikTok Shop, Instagram Shopping, and YouTube Product Shelf so your products appear directly on the platforms where your audience is. Each integration has its own eligibility requirements and setup flow.

All three connect from Apps in your Fourthwall dashboard, where each has its own card: YouTube Product Shelf, TikTok Shop, and Instagram & Facebook Shop. The Connect button is on the page each card opens, not on the Apps page itself.

TikTok Shop​

TikTok Shop lets you tag products in TikTok videos, LIVE streams, and your TikTok profile. Customers can buy directly on TikTok without visiting your shop.

Requirements before connecting:

  • A TikTok account with at least 1,000 followers
  • A TikTok Seller account (separate from your creator account)
  • At least one published product in your Fourthwall shop

How to connect:

  1. Go to Apps in your Fourthwall dashboard.
  2. Click the TikTok Shop card (not TikTok feed, which is a separate app), then click Connect.
  3. Authorize the connection using your TikTok Seller account.
  4. Follow the setup steps to sync your product catalog.

Products sync automatically after connecting. Initial sync can take up to 24 hours.

For full setup instructions and troubleshooting, see:

Instagram Shopping​

Instagram Shopping lets you tag products in Instagram posts, Reels, and Stories. Customers can tap a product tag and go directly to your Fourthwall product page to buy.

Requirements before connecting:

  • An Instagram Business or Creator account
  • A Facebook Page linked to your Instagram account
  • Your Facebook account must be the admin of a Commerce Manager catalog
  • At least one published product in your Fourthwall shop

How to connect:

  1. Go to Apps in your Fourthwall dashboard.
  2. Click the Instagram & Facebook Shop card, then click Connect to link your Meta account.
  3. Authorize access to your Facebook and Instagram accounts.
  4. Follow the prompts to link your product catalog to Commerce Manager.

Product approval by Meta can take 24-48 hours after connecting.

For full setup instructions and troubleshooting, see:

YouTube Product Shelf​

YouTube Product Shelf (also called YouTube Merch Shelf) shows your products below your YouTube videos. Each product links to its page on your Fourthwall shop, and checkout happens there.

Requirements before connecting:

  • A YouTube channel with 500 or more subscribers
  • YouTube Partner Program membership with monetization enabled
  • Your shop and products must be live and publicly accessible, so YouTube's team can review them
  • At least one published product in your Fourthwall shop

How to connect:

  1. Go to Apps in your Fourthwall dashboard.

  2. Click the YouTube Product Shelf card, then click Connect.

Common issues across integrations​

Products not appearing after connecting. Product sync can take up to 24 hours for all integrations. For TikTok Shop and Instagram & Facebook Shop, if products still don't appear after 24 hours, disconnect and reconnect the integration. For YouTube Product Shelf, wait instead of reconnecting: after products sync, Google's review usually takes 3 to 5 days. Contact support@fourthwall.com only if products are still pending more than 5 days after you connected, and include your YouTube channel URL and the product names.

Connection fails during authorization. Make sure you are logged into the correct account (TikTok Seller account, Facebook account with Commerce Manager access, or Google account linked to your YouTube channel) before starting the authorization flow.

Reconnection after a domain change. Adding or switching to a connected custom domain doesn't require you to disconnect and reconnect YouTube Product Shelf or Instagram & Facebook Shop. Fourthwall manages the product links for both.

Product rejected by a platform. Each platform reviews submitted products for policy compliance. If a product is rejected, check the rejection reason in the platform's seller or commerce tools and update the product title, description, or images to meet the platform's requirements.

Frequently asked questions​

Can I connect all three integrations at once?​

Yes. Each integration is independent. You can connect TikTok Shop, Instagram Shopping, and YouTube Product Shelf at the same time from the Apps section.

Do customers complete purchases on the social platform or on my Fourthwall shop?​

It depends on the platform. TikTok Shop handles checkout natively on TikTok. Instagram and YouTube link customers to your Fourthwall product page to complete the purchase.

Will all my products sync automatically?​

All published products sync. Hidden, archived, or out-of-stock products are excluded. Each platform may also apply its own review and approval process before products appear.
