Triggering Text Message on sales_order_shipment_track_save_after via Shipstation

Question

I am attempting to set up a custom trigger so that when Shipstation writes back it sends out a text message via Twilio. I have it working when adding a tracking number from the admin side but does not appear to work when adding tracking number through Shipstation (I am assuming it is using Magentos API). Is there a different event I should be listening to for this?

etc/events.xml

    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
<event name="sales_order_shipment_track_save_after">
    <observer name="mywebsite_model_observer_textshipment"
        instance="MyWebsite\Customizations\Model\Observer\TextShipment" />
</event>

Ran into a similar issue using ShipStation -- doesn't seem to trigger the event sales_order_shipment_track_save_after, instead try using: sales_order_shipment_save_after

And then in your observer, you can get tracking info using the following:

$shipment = $observer->getEvent()->getShipment();
foreach ($shipment->getAllTracks() as $track) {
    var_dump($track->getData()); // get tracking info
}
