So I have a Product property named 'start price' and it is not copied automatically to line item in same property 'start_price', when using line item API. I use hs_product_id to create association between product and line item but it does not help me to inlcude this custom property to line item automatically.
Hi, @DVadachkoria👋 Thanks for your question. Did you get this resolved? If not, can you share an example request body, please? I'd like to set up a quick test and I want to reproduce the call you are making.
