Can you please give me explanation behind partner_line_item_id ?

Hi @velvinayak!
The partner_line_item_id is a unique identifier that you have to assign to line items when creating an order. It has to be unique across all of the line items from all the orders.
It works as an identifier for all of the line items on the account, so it cannot be repeated
Please let me know if that doesn’t help answer the question or I could explain better
Thanks in advance!
