Shopify Products

Create, update, and bulk-import Shopify products. Produces live products in the store via the GraphQL Admin API or CSV import.

Prerequisites

• Admin API access token (use the shopify-setup skill if not configured)
• Store URL and API version from shopify.config.json or .dev.vars

Workflow

Step 1: Gather Product Data

Determine what the user wants to create or update:

• Product basics: title, description (HTML), product type, vendor, tags
• Variants: options (size, colour, material), prices, SKUs, inventory quantities
• Images: URLs to upload, or local files
• SEO: page title, meta description, URL handle
• Organisation: collections, product type, tags

Accept data from:

• Direct conversation (user describes products)
• Spreadsheet/CSV file (user provides a file)
• Website scraping (user provides a URL to extract from)

Step 2: Choose Method

Step 3a: Create via GraphQL (Recommended)

productCreate

mutation productCreate($product: ProductCreateInput!) {
  productCreate(product: $product) {
    product {
      id
      title
      handle
      status
      variants(first: 100) {
        edges {
          node { id title price sku inventoryQuantity }
        }
      }
    }
    userErrors { field message }
  }
}

Variables:

{
  "product": {
    "title": "Example T-Shirt",
    "descriptionHtml": "<p>Premium cotton tee</p>",
    "vendor": "My Brand",
    "productType": "T-Shirts",
    "tags": ["summer", "cotton"],
    "status": "DRAFT",
    "options": ["Size", "Colour"],
    "variants": [
      {
        "optionValues": [
          {"optionName": "Size", "name": "S"},
          {"optionName": "Colour", "name": "Black"}
        ],
        "price": "29.95",
        "sku": "TSHIRT-S-BLK",
        "inventoryPolicy": "DENY",
        "inventoryItem": { "tracked": true }
      },
      {
        "optionValues": [
          {"optionName": "Size", "name": "M"},
          {"optionName": "Colour", "name": "Black"}
        ],
        "price": "29.95",
        "sku": "TSHIRT-M-BLK"
      },
      {
        "optionValues": [
          {"optionName": "Size", "name": "L"},
          {"optionName": "Colour", "name": "Black"}
        ],
        "price": "29.95",
        "sku": "TSHIRT-L-BLK"
      }
    ],
    "seo": {
      "title": "Example T-Shirt | My Brand",
      "description": "Premium cotton tee in multiple sizes"
    }
  }
}

Curl example:

curl -s https://{store}/admin/api/2025-01/graphql.json \
  -H "Content-Type: application/json" \
  -H "X-Shopify-Access-Token: {token}" \
  -d '{"query": "mutation productCreate($product: ProductCreateInput!) { productCreate(product: $product) { product { id title } userErrors { field message } } }", "variables": { ... }}'

Batching multiple products: Create products sequentially with a short delay between each to respect rate limits (1,000 cost points/second).

productUpdate

mutation productUpdate($input: ProductInput!) {
  productUpdate(input: $input) {
    product { id title }
    userErrors { field message }
  }
}

Variables include id (required) plus any fields to update.

productDelete

mutation productDelete($input: ProductDeleteInput!) {
  productDelete(input: $input) {
    deletedProductId
    userErrors { field message }
  }
}

productVariantsBulkCreate

Add variants to an existing product:

mutation productVariantsBulkCreate($productId: ID!, $variants: [ProductVariantsBulkInput!]!) {
  productVariantsBulkCreate(productId: $productId, variants: $variants) {
    productVariants { id title price }
    userErrors { field message }
  }
}

productVariantsBulkUpdate

mutation productVariantsBulkUpdate($productId: ID!, $variants: [ProductVariantsBulkInput!]!) {
  productVariantsBulkUpdate(productId: $productId, variants: $variants) {
    productVariants { id title price }
    userErrors { field message }
  }
}

Step 3b: Bulk Import via CSV

For 20+ products, generate a CSV and import through Shopify admin.

CSV Column Reference

Required columns:

Variant columns:

Image columns:

SEO columns:

Multi-Variant Row Format

The first row has the product title and details. Subsequent rows for the same product have only the Handle and variant-specific columns:

Handle,Title,Body (HTML),Vendor,Type,Tags,Published,Option1 Name,Option1 Value,Variant SKU,Variant Price,Variant Inventory Qty,Image Src
classic-tshirt,Classic T-Shirt,<p>Premium cotton</p>,My Brand,T-Shirts,"summer,cotton",TRUE,Size,Small,TSH-S,29.95,50,https://example.com/tshirt.jpg
classic-tshirt,,,,,,,,Medium,TSH-M,29.95,75,
classic-tshirt,,,,,,,,Large,TSH-L,29.95,60,

CSV Rules

• UTF-8 encoding required
• Maximum 50MB file size
• Handle must be unique per product -- duplicate handles update existing products
• Leave variant columns blank on variant rows for fields that don't change
• Images can be on any row -- they're associated by Handle
• Published = TRUE makes the product immediately visible

Import Steps

1. Generate CSV using the column format above
2. Use the template from assets/product-csv-template.csv if available
3. Navigate to https://{store}.myshopify.com/admin/products/import
4. Upload the CSV file
5. Review the preview and confirm import

Use browser automation to assist with the upload if needed.

Step 4: Upload Product Images

Images require a two-step process -- staged upload then attach.

stagedUploadsCreate

mutation stagedUploadsCreate($input: [StagedUploadInput!]!) {
  stagedUploadsCreate(input: $input) {
    stagedTargets {
      url
      resourceUrl
      parameters { name value }
    }
    userErrors { field message }
  }
}

Input per file:

{
