Core issue: Passing per-product metadata (length, height, width) into Shopify CarrierService rate requests to calculate third‑party shipping costs.
Context: Dimensions are stored via an app as product metadata (metafields—custom fields on products). The poster seeks a way to include these fields in the payload sent to CarrierService, referencing Shopify’s REST API docs (2021-10).
Latest update: Another participant asks whether this is even possible, indicating the same need.
Outcome: No guidance, workaround, or confirmation provided. Key question remains unanswered—whether and how product metafields can be included in CarrierService rate requests. The discussion is open/unresolved.
Dear,
I need to assign extra meta data to each product (length, height, width), these meta data are important to calculate thirdparty shipping.
I am using an app to add product meta data. and i want to know how to pass these data to CarrierService rate request.
