I'm Shopify plus customer.
I want to connect my Shopify and 3rd party company (Local delivery carrier) through API.
However, this delivery company has never connected to Shopify, so I am wondering if this is possible.
When their delivery man update the delivery status to their APP after delivery, I want our Shopify to have their delivery status updated in real time via API.
Looking at this link, can you give me any possibilities and advice?
