Verdicts

Fabric

Public OpenAPI files for about 980 operations, llms.txt, client credentials with role-limited system apps, and a published 99.9 per cent SLA. Access needs a sales contract, with no public price or self-serve trial. The commerce docs are labelled legacy, the newest release notes date from July 2025, and no status page was found.

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

Fabric

  1. Get the tenant ID and a System App client ID and secret from the merchant's Copilot admin, with the narrowest role the task needs
  2. Request a new system token from {authURL}/v1/token every 10 minutes, since system apps receive no refresh token
  3. Send x-fabric-tenant-id on every call, and x-fabric-channel-id where the merchant sells in more than one channel
  4. Page order searches with offset and limit, because the default response returns 10 orders
  5. Read errorCode and context.endpoint in Orders and Inventory errors, and check for duplicates before retrying a write

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
