How to get gift card product ID via storefront API?

[ramblinmatt]

I use the storefront API to add items to a shopify checkout on my non-shopify site. I am trying to add gift cards to the site, but they aren't returned when I do a simple query of products. How can I add a gift card to a checkout?

Here's my simple query that isn't returning any gift cards:

query	{
  products(first:250) {
    edges{
      node {
        id
        title
      }
    }
  }
}
