Connect Container Selection to Your E-Commerce Workflow

Give container selection the right inputs

An order's item dimensions, quantities and available box sizes define the starting point for container selection. Keep the box catalog aligned with fulfillment so the integration recommends containers the operation can actually use.

Match the request to the scenario

The Optipacker Merchant API accepts container and item data at POST /api/v1/optimal-container. Arranged single-SKU scenarios return placement data, with capacity data where supported by the selected mode. Mixed-SKU scenarios use a heuristic estimate and do not return individual placements.

Use that distinction when designing the response handling. A capacity estimate and a placement layout support different decisions on the packing floor.

Handle the full response

Review the recommended container, packing result and any unfulfilled quantities. Decide how your system should handle an order that cannot fit the available options or a request that fails validation. Preserve enough order context for the operator to resolve the exception.

Test with your order mix

Use representative dimensions, quantities and constraints. Include large items, small orders, container limits and orders that need an exception path. Measure response time within your own integration and inspect the returned results before making the workflow operational.

Measure the outcome

Compare selected container sizes, packing exceptions, material use and actual shipping charges against your current process. Keep the same order mix and carrier assumptions when comparing results.
