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

WooCommerce API + MCP

  1. Create a REST key with read permission only for reporting tasks, and send it in the Authorization header, never the URL
  2. Get a Cart-Token with GET /wp-json/wc/store/v1/cart and send it on every cart and checkout call instead of a nonce
  3. Add _fields=id,name,price to REST calls to cut response size
  4. Page with per_page up to 100 and stop at X-WP-TotalPages
  5. Product delete only trashes unless you pass force true, so check the trash before assuming it's gone
