Yes, you can manually export a single item to Shopify for testing purposes. Please note that this function is limited to one export every 10 minutes.

How to trigger the manual export:

1. Open the menu Setup > Markets > Shopify App > Item Export.
2. Select the corresponding webshop (client).
3. Enter the ID of the main item you want to export.
4. Click on Execute.

If the item and its variants meet all export conditions, they will be transferred directly to your Shopify store.

Important note on re-exporting

Item export cleanup must be performed:

1. Turn off item export in the configuration assistant   
   Setup  > Assistants > Omni-Channel > Shopify > Config Assistant > Item Management
2. Open Setup > Markets > Shopify > Help > Item Cleanups and schedule a cleanup
3. The cleanup will automatically run through all items overnight and clear deprecated content
4. The following day, the merchant can reactivate the item export and manually export the item via Shopify Help or wait for the next night so that the export runs automatically
