Creating Fulfillments

Create a fulfillment by marking a shipment as shipped without creating a label. Fulfillments represent the completion of the shipping process and notify customers and order sources that their orders have been shipped.

Requirements

To create fulfillments, you need:

• a valid shipment_id from an existing shipment that hasn't been fulfilled yet
• tracking_number from your carrier
• a valid carrier_code that matches your configured carriers
• your account email to be verified

Create Fulfillments Endpoint

This endpoint can be used to create multiple fulfillments at once.

POST /v2/fulfillments

curl -i -X POST \
  https://api.shipstation.com/v2/fulfillments \
  -H 'Content-Type: application/json' \
  -H 'api-key: YOUR_API_KEY_HERE' \
  -d '{
    "fulfillments": [
      {
        "shipment_id": "se-12345678",
        "tracking_number": "1Z12345E1234567890",
        "carrier_code": "ups",
        "ship_date": "2024-01-15T10:00:00Z",
        "notify_customer": true,
        "notify_order_source": true
      }
    ]
  }'

{
  "has_errors": false,
  "fulfillments": [
    { … }
  ]
}

Error Handling

The create fulfillments endpoint processes requests in batch but returns individual results. Even if some fulfillments fail, others may succeed.
