Metafields are the custom fields you have created on Shopify. To match the metafields to StoreAutomator custom fields, you must first create the custom fields on StoreAutomator. Then, you need to map the custom fields with the target metafields on Shopify from the product data template.
Here are the steps you need to follow:
1- Find and click edit to your Shopify template from “Settings>Templates”.
2- Click the “Add Field” button.
3- Type “metafield” inside the search bar, use the exact typing when you have created the metafield on Shopify and click “Add”.
4- Save the template.
