Is there a way for me to get the number of orders for the day for a product in different shopify stores? For example, store A with product x sold 4 orders that day, store B with product y sold 6 orders that day, store C with product z sold 8 orders stores that day and I don't own those stores. I have read through the api documentation but still haven't found a solution.
Since you don't own the stores and the information is not publicly available, here are your options:
Hope that helps
