Before you call either

Saleor API + MCP

  1. Pass the channel slug on product and checkout queries. Prices and availability are per channel
  2. Send X-Saleor-API-URL and X-Saleor-Auth-Token on every MCP request, with a token holding MANAGE_PRODUCTS and MANAGE_ORDERS
  3. Read the errors array in every mutation payload. A 200 response can still carry a CheckoutErrorCode
  4. Keep queries under the 50,000 complexity cap and 100 items a page, and send at most 4 mutations per request
  5. The 3.24 changelog removes the old dummy payment plugins, so test checkouts should use a payment app

Wix Stores and eCommerce API

  2. Fetch the product first and pass product.revision on every Catalogue V3 update, or the call fails with 409
  3. Use Cart V2 for new work. The older eCommerce Cart and Checkout APIs were deprecated on 5 August 2026
  4. Request cursorPaging.limit of at most 100 on Query Products and use Search Products for lookups by name
  5. Over MCP, read the method page with ReadFullDocsArticle before CallWixSiteAPI. Responses are cut at 50,000 characters by default
