Integration to send customer orders to API

My team and I are looking for an integration feature that will automatically send our customers' orders to an external vendor's API to be fulfilled (with a digital service). How can I get started doing this?
 

Hi MHol, 

That's something possible to achieve with the Orders API. There's more info about that in the links below:
