Accessing 'purchaseable' on product variant in Big Commerce

Question

Does anyone know how to access (programmatically) whether a product variant is 'purchasable' in Big Commerce (see attached image)? I've tested the product object (docs) - nothing there. Also can't see anything that returns this value via GQL (docs). So can 'purchasable' be accessed? Or does it only exist to display a pop-up to the user when they select an item that isn't 'purchasable'?

Answer 1

Should have waited out a bit longer because it can be done with GQL - which may be helpful to others:

query productById(
  $productId: Int!
  # Use GraphQL Query Variables to inject your product ID
) {
  site {
    product(entityId: $productId) {
      id
      entityId
      name
      variants {
        edges {
          node {
            sku
            isPurchasable
          }
        }
      }
    }
  }
}

Just note that the product needs to be 'visible on storefront'
