  • If the connection status shows Active, your integration is complete.
  • If your connection doesn’t show as Active, review your WooCommerce settings and make sure the REST API and Permalinks are configured correctly.
  • If issues persist, reach out to Merchize Support for assistance. 

You will be redirected to the page of WooCommerce and be asked for approval. If you do not log in, you need to log in your WordPress site to approve this connection.

What Happens After Integration?

Once the connection is active, Merchize will automatically handle order syncing and fulfillment:

  • When a customer places an order on your WooCommerce site (status changes to Processing), the order is automatically imported into your Merchize Orders page.
  • Merchize will automatically create a product corresponding to the item in the order. If the product already exists, it will be mapped again.
  • You’ll need to upload artwork (PNG file for front/back) for Merchize to fulfill the product. Once uploaded, Merchize saves it so you don’t have to re-upload for future orders.
  • Merchize’s team fulfills the order and updates the status in Merchize.
  • Tracking information is automatically pushed back to WooCommerce, appearing in Customer Notes on the order, so your customers can stay updated.

That’s it! Your WooCommerce store is now integrated with Merchize. Orders placed in WooCommerce will sync directly to Merchize for fulfillment, saving you time and effort.
