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

Snipcart API + MCP

  1. Use the agent for back-office jobs (orders, refunds, discounts, stock, abandoned carts), not for placing orders
  2. Start with a test-mode key (ST_ prefix) before switching to live (SL_)
  3. Send the key in X-Snipcart-Api-Key. OAuth-only clients can't connect
  4. Stay under 100 MCP requests a minute and 10 in flight per key
  5. Ignore unknown response fields. Snipcart adds fields without a new version
