Yes, you can edit the information that will appear on the certificate even after you have activated certification.
The Verisart App creates basic certificates using the information you've already provided to Shopify: The product's title, image and description. We strongly recommend that you provide additional details to make your certificates more complete. This will give your customers full confidence in the accuracy and authenticity of the certificate and their purchase.
You can choose from three levels of object validation. Learn more about object validation in our article Understanding object detail validation levels.
Editing a single product
Object Details form
This is the easiest way to add additional information: Just edit the fields that appear in the Object Details form when you click on the title of the certificate. We recommend that you provide at least the information in the Basic and Recommended panels.
Editing multiple products
To use this option and make it easier to add details for multiple products, select more than one product and then 'Edit Products'.
The Bulk Editor opens in a new tab. It allows you to easily enter all the required data.
Please refer to our Shopify Metafield Guide for Verisart to ensure you are entering the data correctly.
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.
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.
