Usage

Example 1: Get Shop Information

1. Add the Shopify GraphQL node
2. Select Execute Query operation
3. Enter this query:

{
  shop {
    name
    email
    currencyCode
    primaryDomain {
      url
    }
  }
}

Example 2: Get Collection by Name

1. Add the Shopify GraphQL node
2. Select Get Collection by Name operation
3. Enter the exact collection name as it appears in Shopify (e.g., Shop All name of your collection)
4. The node will return the collection details with all products and their variant SKUs (up to 250 products)

Use case: Perfect for exporting all SKUs in a specific collection, syncing inventory, or analyzing collection contents.

Note: Use the exact collection title as shown in your Shopify admin under Products > Collections.

Example 3: Get Product by SKU

1. Add the Shopify GraphQL node
2. Select Get Product by SKU operation
3. Enter the SKU (e.g., ABC-123)
4. The node will return the product with all its variants, pricing, inventory, and images

Returned data includes:

• Product details (title, description, status, handle)
• Variant details (id, title, price, SKU)
• Inventory item IDs for each variant (useful for inventory management APIs)
• Product images

Example 4: Get Products with Status Filter

1. Add the Shopify GraphQL node
2. Select Get Products operation
3. Choose status filters: Active, Archived, or Draft (can select multiple)
4. (Optional) Enter Exclude Tags to filter out products with specific tags (e.g., skip, discontinued)
5. Choose retrieval mode:
   • Return All = OFF: Set a limit (default: 10) to get a specific number of products
   • Return All = ON: Automatically fetch all products using pagination (no limit needed)
6. The node will return filtered product details including variants

Returned data includes:

• Product details (title, description, handle, status, dates)
• Up to 10 variants per product (id, title, price, SKU)
• Inventory item IDs for each variant (for inventory management integrations)

Filtering options:

• Status: Filter by product status (Active, Archived, Draft)
• Exclude Tags: Comma-separated list of tags to exclude. Products with ANY of these tags will be filtered out. For example, entering skip, test will exclude all products tagged with either "skip" or "test".

Note: All product operations (Get Products, Get Product by SKU) return the inventoryItem.id field for each variant, which is required for Shopify's Inventory API operations.

Example 5: Get All Products with Pagination

1. Add the Shopify GraphQL node
2. Select Get Products operation
3. Enable Return All toggle
4. Optionally filter by status (Active, Archived, Draft)
5. Optionally add Exclude Tags to skip products with specific tags
6. The node will automatically paginate through all results and return ALL products matching your filters

Note: When "Return All" is enabled, the node makes multiple API requests (250 products per request) until all products are retrieved. This is useful for bulk operations or data exports.

Example 6: Custom Query with Variables

1. Add the Shopify GraphQL node
2. Select Execute Query operation
3. Enter a query with variables:

query GetProduct($id: ID!) {
  product(id: $id) {
    id
    title
    description
  }
}

4. Add variables in JSON format:

{
  "id": "gid://shopify/Product/1234567890"
}

Example 7: Update Inventory for Multiple Items

1. Add the Shopify GraphQL node
2. Select Update Inventory operation
3. Enter your Location ID (e.g., gid://shopify/Location/59462222017)
4. Select a Reason for the adjustment (correction, restock, etc.)
5. Enter Inventory Items as a JSON array:

[
  {
    "inventoryItemId": "gid://shopify/InventoryItem/123456",
    "quantity": 100
  },
  {
    "inventoryItemId": "gid://shopify/InventoryItem/789012",
    "quantity": 50
  },
  {
    "inventoryItemId": "gid://shopify/InventoryItem/345678",
    "quantity": 75
  }
]

Use case: Perfect for batch inventory updates from external systems, syncing stock levels, or applying bulk adjustments after physical counts.

Key points:

• Updates up to 250 items in a single API call
• Sets absolute quantity values (not deltas)
• Returns the adjustment group with delta changes and final quantities
• Returns both available and on_hand inventory changes
• Each change includes the inventory item ID and SKU for easy identification
• Inventory item IDs can be obtained from any "Get Products" or "Get Product by SKU" operation

Response structure: The operation returns detailed information about what was updated:

• inventoryAdjustmentGroup.id - Unique ID for this adjustment batch
• changes[] - Array of all inventory changes made
  • name - Type of inventory (available or on_hand)
  • delta - How much the inventory changed (e.g., +50, -10)
  • quantityAfterChange - Final quantity (may be null with ignoreCompareQuantity)
  • item.id - Inventory item ID that was updated
  • item.sku - SKU of the variant (for easy identification)

Troubleshooting

Node doesn't appear in n8n

1. Make sure you've run npm run build before linking or installing
2. Restart n8n after installation
3. Check that the dist folder exists in the package directory
4. For Docker: Verify the volume mount and N8N_CUSTOM_EXTENSIONS environment variable

Authentication errors

1. Verify your Shop Name doesn't include .myshopify.com (just the store name)
2. Ensure your access token has the required API scopes
3. Check that your API version is correct (format: YYYY-MM)
4. Test your credentials using the "Test" button in n8n

GraphQL errors

1. Verify your query syntax using Shopify's GraphQL Explorer
2. Check that you have the required scopes for the data you're querying
3. Ensure variables are valid JSON format
4. Review Shopify's rate limits

Common issues

• "Cannot find module 'n8n-workflow'": Run npm install in the package directory
• Empty results: Check your store has data and your API version supports the query
• Timeout errors: Reduce the limit parameter or optimize your query

Development
