Referencia API Ship-ify

Guía completa para integrar la API de optimización de embalaje Ship-ify en tus aplicaciones.

API Interactiva (Swagger)

Descripción general

La API Ship-ify proporciona optimización de embalaje 3D para envíos de comercio electrónico. Dado un conjunto de tamaños de cajas disponibles y artículos a enviar, la API calcula la configuración de embalaje óptima para minimizar los costos de envío mientras maximiza la utilización de las cajas.

Optimización rápida

Resultados en milisegundos con algoritmos avanzados

Embalaje 3D

Embalaje 3D real con soporte de rotación

Restricciones de peso

Respeta los límites de peso para cada tipo de caja

Visualización

Visualización HTML 3D (Pro y Empresarial)

Autenticación

Todas las solicitudes API requieren autenticación usando una clave API. Incluye tu clave API en los encabezados de la solicitud:

Authorization: Bearer YOUR_API_KEY

Important: Mantén tus claves API seguras. Nunca las expongas en código del lado del cliente o en repositorios públicos.

Puedes generar claves API desde tu panel de control.

Endpoints

POST/api/v1/shipping-optimize

Optimizar el embalaje de un conjunto de artículos en las cajas disponibles.

Cuerpo de la solicitud

Objeto JSON que contiene boxes, items y options (ver Formato de solicitud)

GET/api/v1/shipping-optimize

Recuperar capacidades de la API, estadísticas de uso y ejemplos de solicitudes para tu nivel.

Respuesta

Objeto JSON con capacidades del nivel, información de cuota y estadísticas de uso

Conjuntos de cajas

Los conjuntos de cajas te permiten guardar y reutilizar configuraciones de cajas en las solicitudes API. En lugar de enviar el array completo de cajas con cada solicitud, puedes referenciar un conjunto guardado por su clave única.

Tip: Crea conjuntos de cajas separados para diferentes escenarios de envío, como cajas de cartón estándar vs cajas aisladas para artículos sensibles a la temperatura.

Gestión de conjuntos de cajas

Crea y gestiona tus conjuntos de cajas desde el panel de conjuntos de cajas. Cada conjunto obtiene una clave única como bs_abc123xyz456.

Uso de conjuntos de cajas en solicitudes

Usa boxSetKey en lugar del array boxes:

{
  "boxSetKey": "bs_abc123xyz456",
  "items": [
    {
      "id": "item-001",
      "name": "Product A",
      "dimensions": { "length": 4, "width": 3, "height": 2 },
      "weight": 1.5,
      "quantity": 2
    }
  ],
  "options": {
    "algorithm": "shipify-ultra"
  }
}

Understanding Weight Constraints

The API supports two distinct types of weight constraints:

Box Structural Limit (weightCapacity)

Set on each box type. This represents the maximum weight the box material can physically hold without breaking. The optimizer will not place items that would exceed this structural limit.

"boxes": [{ "id": "medium", "weightCapacity": 25, ... }]
Carrier Shipment Limit (maxShipmentWeight)

Set in options. This represents the carrier threshold above which overweight fees apply. All shipments will be optimized to stay under this limit regardless of box capacity. When this option is set, all items must have a weight property defined.

"options": { "maxShipmentWeight": 50 }
Overweight Item Handling (overweightItemHandling)

When a single item exceeds the maxShipmentWeight, this option controls how it's handled:

  • "allow" (default): Item is allowed to ship alone in a box, weight limit waived for this shipment
  • "unpacked": Item is placed in the unpackedItems array with reason
"options": { "maxShipmentWeight": 50, "overweightItemHandling": "unpacked" }

Both constraints are enforced simultaneously. A shipment must satisfy both the box structural capacity and the carrier weight limit.

Pedidos por lotes

Process multiple orders in a single API request. Instead of sending individual items, you can send an array of orders, each with its own items. The API will optimize packing for each order independently and return consolidated results.

Availability: All tiers

Batch order processing is available for all subscription tiers with the same limits.

Batch Limits

Limit TypeValue
Max Orders per Batch50
Max Items per Order100
Max Total Items per Batch500

Batch Request Format

Use the orders array instead of items. Each order must have an orderId and its own items array.

Backward Compatibility

The original single-order format using items array continues to work. Batch processing is only triggered when the orders array is present.

Formato de respuesta

Successful responses include shipment details, packing statistics, and metadata.

Response Structure

FieldDescription
successBoolean indicating request success
data.shipmentsArray of shipment objects with packed items
data.unpackedItemsItems that couldn't fit in any box
data.summaryAggregated statistics (total cost, utilization, etc.)
data.suggestionsOptimization suggestions
metadataAlgorithm used, execution time, tier info
visualizationHtml3D HTML visualization (Pro+ only)

Box Structure in Shipments

Each shipment contains a box object with the following fields:

FieldTypeDescription
idstringBox ID (from your submitted boxes, or "custom-*" for oversized items)
namestringBox name (or "Custom Box" for oversized items)
dimensionsobject{ length, width, height } of the box
costnumberBox cost (optional, 0 for custom boxes)
typestring"custom" when oversizedItemHandling is "custom-box" (only present for custom boxes)

Packed Items Structure

Each packed item in a shipment includes the following fields:

FieldTypeDescription
itemIdstringOriginal item ID as submitted in the request
itemIndexnumberIndex within quantity expansion (0, 1, 2, ...). For items with quantity > 1, each instance gets a unique index.
positionobject{ x, y, z } coordinates of item placement in the box
rotationobjectAxis mapping showing how item was rotated to fit
rotatedDimensionsobject{ length, width, height } after rotation applied

Rate Limit Headers

Every response includes rate limit information:

Algoritmos

Choose the algorithm that best fits your use case. Algorithm availability depends on your subscription tier.

first-fitBasic+

Fast, simple algorithm that places items in the first available space. Best for speed-critical applications.

best-fitBasic+

Finds the best fitting space for each item, improving utilization over first-fit.

guillotineBasic+

Divides space into rectangles for efficient 2D packing. Good balance of speed and utilization.

max-rectsPro+

Advanced algorithm maintaining multiple free rectangles for optimal packing.

shipify-ultraAll Tiers (Default)

Our smartest algorithm, optimized for both binning (grouping items into separate shipments) and packing (placing items into the smallest possible box). Uses look-ahead optimization, post-pack consolidation, and multi-pass refinement to minimize total boxes and maximize space utilization. Best for most use cases.

shipify-fitPro+

Combines global box selection strategy with fast 3D placement. Uses O(items × boxes × positions) complexity for efficient packing with excellent results.

shipify-maxBasic+

Weight-based grouping algorithm that groups items by order, splits bundles exceeding weight limits, consolidates small bundles, and validates each bundle with 3D packing. Ideal for multi-order shipments where weight-based grouping is preferred.

shipify-physicsAll Tiers

Physics-aware packing algorithm that prioritizes heavier items at the bottom for stability, respects fragility levels (0-5), enforces load capacity limits, and validates center of gravity balance. Includes support area validation (70% minimum) and rotation constraints for fragile items. Advanced features (fragilityLevel, maxTopLoad) require Pro or Enterprise tier.

Why We Count Items, Not API Requests

Batching multiple orders into a single API call is more efficient for everyone. Charging per item optimized aligns with our CPU costs and encourages you to batch orders for maximum efficiency. This means you can send 100 orders in one batch request and pay the same as 100 individual requests with one order each.

Usage limits are based on items processed per month (counting item quantities). Limits reset on the 1st of each month. When you exceed your limit, the API returns a 429 status code with details about your usage.
