Update product information with GraphQL

Shopify Apps
1

Hey, i’m doing an automation on GraphQL… and i’m little stuck on updating a existing product, i need 3 mutations:

  • Update product information (title, descriptionHtml, barcode, SKU).
  • Update product value (unit cost and price)
  • Update product stock (inventory quantity)

IF this first option is not possible, i can do all on one mutation, but i was hoping to make the first option work.

Hey @flavio_ns ,

Thanks for reaching out! No worries at all—here’s how you can update a product using GraphQL in Shopify. You can break it down into three separate mutations:

  1. Update Product Information:

Use productUpdate to update the title, description, barcode, and SKU.

mutation UpdateProductInfo($input: ProductInput!) {
  productUpdate(input: $input) {
    product {
      id
      title
      descriptionHtml
      variants(first: 10) {
        edges {
          node {
            id
            sku
            barcode
          }
        }
      }
    }
    userErrors {
      field
      message
    }
  }
}

Variables Example:

{
  "input": {
    "id": "gid://shopify/Product/123456789",
    "title": "New Product Title",
    "descriptionHtml": "

Updated description

",
    "variants": [
      {
        "id": "gid://shopify/ProductVariant/987654321",
        "sku": "NEW-SKU",
        "barcode": "1234567890123"
      }
    ]
  }
}
  1. Update Product Price and Cost:
mutation UpdateProductPrice($input: ProductVariantInput!) {
  productVariantUpdate(input: $input) {
    productVariant {
      id
      price
      inventoryItem {
        unitCost {
          amount
        }
      }
    }
    userErrors {
      field
      message
    }
  }
}

Variables Example:

{
  "input": {
    "id": "gid://shopify/ProductVariant/987654321",
    "price": "29.99",
    "inventoryItem": {
      "id": "gid://shopify/InventoryItem/123456789",
      "unitCost": {
        "amount": "15.00"
      }
    }
  }
}
  1. Update Inventory Quantity:

Use inventoryAdjustQuantity to update stock levels.

mutation UpdateInventory($input: InventoryAdjustQuantityInput!) {
  inventoryAdjustQuantity(input: $input) {
    inventoryLevel {
      id
      available
    }
    userErrors {
      field
      message
    }
  }
}

Variables Example:

{
  "input": {
    "inventoryLevelId": "gid://shopify/InventoryLevel/987654321",
    "availableDelta": 10
  }
}

@pal3kuno ,

Sure! Please feel free to reach out in my signature below—out with more details about where you’re trying to retrieve the ProductVariant ID. If you’re using Shopify’s GraphQL API, you can fetch it using a query like this:

{
  productVariants(first: 10) {
    edges {
      node {
        id
        title
      }
    }
  }
}

Let me know how I can assist you further!
