Include this in the `x-spree-token` header for guest access to that specific order. ## Response Format All responses are JSON. List endpoints return paginated responses with `data` and `meta` keys. ## Error Handling Errors return a consistent format: ```json { "error": { "code": "record_not_found", "message": "Product not found" } } ``` version: v3 servers: -
