​
Product Locator Format

When creating an order for a Shopify product, use the productLocator parameter with the Shopify product URL and variant ID: 
{
    "lineItems": [
        {
            "productLocator": "shopify:https://www.gymshark.com/products/gymshark-arrival-5-shorts-black-ss22:39786362601674"
        }
    ]
}
The format for the product locator is shopify:<product-url>:<variant-id>, where:
  • shopify: is the prefix identifying this as a Shopify product
  • <product-url> is the full URL to the product page
  • <variant-id> is the unique variant ID for the specific product option (size, color, etc.)
