Wix Stores and eCommerce API C

Good for An agent managing a merchant's existing Wix store or building a headless storefront on Wix.

Also in its favour

  • A hosted endpoint, with nothing to install

Verdicts

Shopware

MIT-licensed core with OpenAPI specs for both APIs and a built-in MCP server that advertises three discovery tools, previews writes by default and limits each integration to an allowlist. The MCP server is experimental until 6.8, and 20 security advisories were published between May and September 2026, four of them critical.

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

Shopware

  1. Ask the merchant for an integration without --admin, tied to an ACL role and an MCP allowlist. Send sw-access-key and sw-secret-access-key headers to /api/_mcp
  2. Call shopware-tool-search first, then shopware-toolset-enable, and keep the Mcp-Session-Id header. A fresh session lists only three tools
  3. Pass dryRun=false to commit a write. shopware-media-upload has no dry run and uploads at once
  4. For shopping, call the Store API over HTTP with the sales channel's sw-access-key and keep the sw-context-token. The Store API MCP endpoint has no cart tools in core
  5. Send includes in search criteria to cut response size, and read the 429 body for the wait time

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
