If your orders are not coming through Shiptheory, there are a couple of things you need to check:
1. From your Magento 2 admin panel, go to Stores >> Configuration >> Shiptheory >> Setup, and check that the integration is enabled. Also, check that you have the correct API Key and API Secret.
2. Another thing to check is that you have the correct store address or URL. If you've recently change from staging to live site, then you need to update the connection to reflect this change.
3. Lastly, you need to take note that only orders that you 'ship' will be sent to Shiptheory for processing.
