When setting up your Instagram campaign, you can select an existing product from your Shopify product catalog or manually enter the name of a custom product.
But sometimes, you may be unable to find your product or variant for various reasons. This isn't a problem. If you can't find your product or variant, just select 'Use a custom prize,' and you'll be able to manually enter the name of your prize on the next page.
Selecting 'Use a custom prize' will have no negative impact on your Instagram giveaway campaign or limit what prize you can use for your campaign.
