The sync between Shopify and Marketplacer won't work if the new products and images are being uploaded at the same time because Marletplacer doesn't recognize where to put the image data unless the product information is input first.
Here are instructions regarding how to complete this process:
1. First, login to your Shopify account and create a new product. For this example, we've created a latte.
Note that we did not add an image.
You should input the required product details, such as the SKU and price, which will sync during the integration and turn into adverts in Marketplacer.
2. Click Save. Your new product has been created, which will trigger a sync to Marketplacer. Next you can add an image to your newly created product.
This will create another update which will automatically sync to Marketplacer, and now the product will include images.
