Hi @tcmleung , and you don't use Draft order? I use Draft order to add some custom line items, and now I want it works with discount code. Can you quick guide me, please?
@tcmleung@AndyHung were you able to figure that out? I have the same situation here. I have a draft Order and I need to apply the discount code to it but I can't find the endpoint for that.
Also looking for a solution here. Want my sales team to be able to take orders over the phone and build them using draft orders. Need them to be able to apply the clients discount code for tracking and ensuring there aren't issues with the discount.
