List your products
List the products you set up in CustomCat (a design on one or more catalog items) with variants, SKUs, cost, price, stock flag and design images. Use the variant SKUs when placing an order for these products. GET /product.
pagelimitsince_idupdated_sinceGet one of your products
One of your CustomCat products by id (e.g. 22-2580581): variants, SKUs, cost, price, options, designs. GET /product/{product_id}.
product_id必填List your designs
List the designs uploaded to your CustomCat account: id, name, tags, image URLs, default product and last-updated time. GET /design.
pagelimitsince_idupdated_sinceList catalog categories
The CustomCat catalog categories (Digisoft, Sublimation) and their subcategories (e.g. T-Shirts, Sweatshirts, Bags), to narrow customcat_list_catalog. GET /catalogcategory.
無需輸入參數。
List the blank-product catalog
Browse the full CustomCat catalog of printable blank products (the items you can order with your own artwork). Filter by category and subcategory from customcat_list_catalog_categories. The reply carries the total in `total`. GET /catalog.
pagelimitcategorysubcategoryGet a catalog product
One catalog product by numeric id with its colors, sizes and SKUs. GET /catalog/{catalog_product_id}.
catalog_product_id必填Get a catalog SKU (stock check)
One catalog SKU with its price and stock status. Use it before ordering: a SKU that is out of stock, discontinued or invalid makes the order fail. GET /catalog/sku/{catalog_sku_id}.
catalog_sku_id必填List shipping methods
The shipping methods CustomCat offers for a destination country (ids and names). The method name is required when placing an order. GET /shipping.
country_codeGet the shipping cost for items
Calculate the shipping cost of one shipping method for a destination and a list of catalog SKUs with quantities. Read-only quote: it places nothing. POST /shipping/{shipping_id} (shipping_id from customcat_list_shipping_methods).
items必填stateshipping_id必填country_codeGet order status
Status of an order by YOUR order id: order status (Pending, Verified, Shipped), per-item production status, shipments with tracking ids, totals and the ship-to address. Set sandbox=true to look up a sandbox test order. GET /order/status/{order_id}.
sandboxorder_id必填Place an order
WRITE: place an order for CustomCat to print and ship. This CHARGES the payment method on file in your CustomCat account (product cost + shipping; a front+back print adds $5 per line item) unless sandbox=true, which only validates the order. A real order (sandbox=false) also needs confirm=true, set only after the user confirmed it. The order id is yours and must be new (a duplicate is rejected). Needs the Write API key. Check stock with customcat_get_catalog_sku and the method name with customcat_list_shipping_methods first, and confirm the details with the user before calling. POST /order/{order_id}.
