Verdicts

Elastic Path API + MCP

Cart, promotion code, checkout and order endpoints cover the whole test flow. MCP server exposes 95 tools with full CRUD, no read-only mode and no public source or licence.

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.

Before you call either

Elastic Path API + MCP

  1. Use a client_credentials token server-side only. It has full CRUD on the store
  2. Pick the base URL for the store's region (useast or euwest), or every call returns 401
  3. Loading the MCP server costs 95 tool definitions, so enable it only for agents that need the back office
  4. On a 429, wait a few seconds and retry. No Retry-After header is sent
  5. Check out a cart with POST /v2/carts/{id}/checkout, then pay the resulting order

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
