Note: At any point if Shopify happens to update any of the fields you’ve included in your update-feed, then the information will be overridden
When creating an update-only feed file, you must include the ID column. Any other column after that is optional or dependent on what you want to update. For example, if you only want to add size information and additional images, then the file looks like this:
| ID | Size | additional_image_link |
|---|---|---|
