Once an order has been shipped, SPOD will send all necessary information to your Shopify Store. For example, if the parcel has a tracking number, we will communicate it to Shopify.
Please be aware that SPOD does not send email confirmation to you or the customer. Shipping confirmations need to be set up via Shopify. You can find more information on this topic here: Emailing order status updates.
We also have an article to help you with the process: How can I provide a shipping confirmation to my customer?
