The Override feature will easily allow you to switch out a product you are currently selling from another supplier (i.e. AliExpress or Oberlo) with the one you've found on Zendrop. Check out the tutorial video we've put together below, and here is the step by step process:
Log in to your Zendrop account.
Search for the product you wish to sell from Zendrop.
Click the Add to Import List button when you've found the product.
Click the Import List tab at the top of your Zendrop account.
Select More Actions - Select a Product to Override option.
Select the existing product from your Shopify store that you want to swap out.
Match the Zendrop variant(s) to your Shopify variant(s).
Click the Override button.
You're all done! You've successfully swapped out the product you were selling in your store for the product you selected on Zendrop. This means you don't have to touch the links in your Facebook ads or the Content IDs for your audiences on Facebook. It's as simple as that!
