Answer 1

The question was just for knowledge sharing purpose .
One can understand some points from Ref_Link
// $order_id = Order ID
$_order = Mage::getModel('sales/order')->load($order_id);
if($_order->canShip())
{
$shipmentId = Mage::getModel('sales/order_shipment_api')->create($_order->getIncrementId(), $itemsarray ,'your_comment' ,false,1);
echo $shipmentId; // Outputs Shipment Increment Number
$trackmodel = Mage::getModel('sales/order_shipment_api')
->addTrack($shipmentId,'your_shipping_carrier_code','your_shipping_carrier_title','carrier_tracking_number');
}
$itemsarray = format explained here Ref_link
Thats it !
A simple code snippet .
Hope it helps someone .

The accepted answer is correct and worked for me on CE 1.9, but I wanted to expand on it.
You don't need to bother with the $itemsQty parameter, you can pass an empty array(), or leave it out altogether. It's an optional parameter, and the method prepareShipment() in app\code\core\Mage\Sales\Model\Service\Order.php will check for that data and perform a lookup if necessary.
If you want to include the tracking number in the shipment email, make sure you add the tracking first and then use Mage::getModel('sales/order_shipment_api')->sendInfo($shipmentIncrementId).
Code Snippet:
$shipmentApi = Mage::getModel('sales/order_shipment_api');
//pass false for email, unless you want Magento to send the shipment email without any tracking info
//could also be written as $shipmentIncrementId = $shipmentApi->create($order->getIncrementId());
$shipmentIncrementId = $shipmentApi->create($order->getIncrementId(), array(), '' , false, 0);
//add tracking info ($shippingCarrier is case sensitive)
$shipmentApi->addTrack($shipmentIncrementId, $shippingCarrier, $shippingTitle, $trackingNumber);
//send shipment email with tracking info
$shipmentApi->sendInfo($shipmentIncrementId);
create() method signature:
public function create($orderIncrementId, $itemsQty = array(), $comment = null,
$email = false, $includeComment = false)
See app\code\core\Mage\Sales\Model\Order\Shipment\Api.php for all methods.
