Printful Synced Products Not Appearing in Storefront API Collection Query

Hydrogen and Storefront APIs
1

I’m relatively new to working with the Shopify API, so I apologize if I’m missing something obvious. I’m building a website that needs to display products from my Shopify store, specifically those that are synced from Printful.

I’m using the Storefront API to query a collection that should contain these products, but I’m getting empty results even though the products exist and are visible in my Shopify admin. Importantly, these products are functioning perfectly on my actual Shopify storefront and customers are successfully purchasing them - the issue is only with accessing them via the API.

When I query the Printful API, I can see all my synced products:

{
  "code": 200,
  "result": [
    {
      "id": 123456789,
      "external_id": "1234567890123",
      "name": "Product Name 1",
      "variants": 9,
      "synced": 9,
      "thumbnail_url": "https://cdn.shopify.com/s/files/1/0000/0000/0000/files/product-image.jpg",
      "is_ignored": false
    },
    // Additional products...
  ],
  "paging": {
    "total": 8,
    "limit": 20,
    "offset": 0
  }
}

However, when I query my Shopify collection via the Storefront API, I get an empty products array:

{
  collection: {
    title: 'Clothing / Merch',
    onlineStoreUrl: 'https://example-store.myshopify.com/collections/clothing-merch',
    products: { edges: [], pageInfo: [Object] }
  }
}

Here’s the query I’m using:

query getCollectionById($id: ID!) {
  collection(id: $id) {
    title
    onlineStoreUrl
    products(first: 50) {
      edges {
        node {
          id
          title
          handle
          availableForSale
          description
          onlineStoreUrl
          featuredImage {
            url (transform: {
              maxHeight: 400,
              maxWidth: 400,
              crop: CENTER
            })
          }
          priceRange {
            minVariantPrice {
              amount
              currencyCode
            }
          }
        }
      }
      pageInfo {
        hasNextPage
        endCursor
      }
    }
  }
}

This query works fine for non-synced products. I’m not trying to create a full storefront, just list products and link to them on my website.

  1. Is there a known issue with Printful-synced products not being accessible via the Storefront API?
  2. Are there specific settings that need to be enabled for Printful products to be accessible via the API?
  3. Is there an alternative approach to get product URLs and basic information for Printful-synced products?
  4. Should I be using the Admin API instead for this specific use case?

Any insights or guidance would be greatly appreciated!

Hey @jovian,

how did you obtain your Storefront API access token?
When your access token is linked to a specfic sales channel, only products contained in the “publication” of the sales channel are accessible.

The easiest way to check if this could be the issue is to compare if your syned and non-synced products are linked to different sales channels. You can do so via the admin dashboard.

You were exactly right! That was the issue.

I created my Storefront API token when setting up a custom app, but didn’t realize it was linked to a specific sales channel. The Printful products weren’t published to that channel, only to the online store.

I checked the products as you suggested and once I updated the sales channel settings, everything started working immediately.

Thanks for the help!
