After integrating Printful with your ecommerce platform, there are two ways you can add products to your store.
Product Push Generator
The first way is to use our product push generator. Simply go to Stores → Add within your Printful account. From there, pick your product, colors, and sizes, and add your design. From there you can write your description, choose your images and price, then automatically send this product to your storefront.
Not all of our integrations support our product push generator. In these cases, you will have to manually sync them. To do this, you will first add your products to your ecommerce shop. Once you have done this, you will go to Stores → Sync within your Printful account. There you will select "Edit" next to each product and assign the proper products, print files, mockups, etc.
You can also Duplicate your existing products to list products with similar variables (i.e., sizes, colors, branding options). Edit the copy to change or add another design or make changes to selected variables. Learn how to do it here.
