This article describes the SKU-level control of Product and Image Data for products listed to BigCommerce or Shopify. (If you haven't yet, you should take a look at the Integration instructions for either Shopify or BigCommerce.)

Normally, the sending of product data is controlled on your Integration Settings page:

However, it is also possible to override this per-SKU. Edit the SKU, then click Advanced Settings on your Shopify or Bigcommerce integration cards:

You should see the three radio buttons below for both Images and Product data:

By default, all SKUs are set to Inherit, which will inherit the settings from the Integration page.
​
​Send will override the Integrations page and send Image or Product Data over to shopify for just this SKU.
​
​Don't Send will not send the Image or Product data, again regardless of the current setting on your integrations page.
