Verdicts

Shopify API + MCP

Typed GraphQL schemas with quarterly versions supported at least 12 months. Closed platform. You can't self-host or change checkout internals.

Wix Stores and eCommerce API

The developer docs are served as Markdown with an llms.txt index, and API keys carry permission scopes and a site restriction. No numeric REST rate limit or OpenAPI file was found, and status.wix.com records a platform-wide incident of 3 hours 17 minutes on 1 August 2026. A person must create the account and the key.

Before you call either

Shopify API + MCP

  1. Pin an API version in the URL and plan to move at least once a year. Old versions fall forward to the oldest supported one
  2. Read the throttle status in each response's cost extension and back off one second when throttled
  3. Send an agent profile in meta on every UCP call, and an idempotency key on every checkout write
  4. Check userErrors on every mutation. A 200 response can still carry a failed write
  5. Add @shopify/dev-mcp while writing code so the agent checks queries against the current schema

Wix Stores and eCommerce API

  1. Send the API key in Authorization with wix-site-id for site calls or wix-account-id for account calls, never both
  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
