I want to integrate a shipment service to Shopify as embedded, not with store app, I am looking for direct endpoint integration. It's seems required Shopify side development.
To be understood I will support my question with screenshots.
In Shopiy Admin > Settings>Shipping and Delivery> Accounts and integration> click Manage integrations > Connect carrier account>
I want to show my shipping and fulfillment service on this list. Is it possible?
