There are several ways to edit multiple certificates or NFTs.

Bulk editor

Follow these steps from the Shopify Products list or from the Products tab in the Verisart app.

  1. Select multiple products

  2. If you are on the Shopify Products list: Click "More actions" and choose "edit in Verisart". If you are in the Verisart app click "Edit Products"

  3. The Bulk Editor opens in a new tab. It allows you to easily enter all the required data

4. You can use the 'column' button to add or remove metafields

5. Don't forget to save before returning to the Verisart App in the other tab.

External metafields app

  • You can use the external app Matrixify to edit all your products' metafields at once and then import them into your catalog. (Shopify's default bulk import feature doesn't support metafields). If you're using Matrixify, the best approach is to:

    • Export your entire product list from Shopify

    • Edit the exported CSV file and add the columns required for Verisart certification

    • Add the missing data for the required columns, and where, necessary, the optional columns

    • Please refer to our Shopify Metafield Guide for Verisart to ensure you are entering the data correctly

    • If a product doesn't require an optional field, e.g., edition_volume or depth, then just leave the values for those products blank

    • When you've finished editing, use Matrixify to upload the CSV with metafields back into your store

    • Once the upload is complete, go to the Verisart App Products tab and Mark products for certification. This will trigger the validation check which will display a warning message if there are any issues with the data you've added.

Shopify API

If you're technical or have a developer building or supporting your store, then using the Shopify API to populate metafields is a great option. It means that you can programmatically populate the object details without having to manually enter data. The main information you'll need is in the Shopify Metafield Guide for Verisart. If you have specific questions about the API option, get in touch with us at

Note: Metafields will need to be correctly formatted to ensure NFTs or certificates of authenticity are correctly issued.

Please refer to our Shopify Metafield Guide for Verisart to ensure you are entering the data correctly.
