Super Discount Daily commented on Overwrite product in XML API

Hello,

Thanks for the quick turnaround! Yes, I will be moving to json as well, but we just needed to start getting the products in as much as we could.

So, currently using XML, and I am using CURL (code given below) - we cannot overwrite it, even if product with the same handle already exists? Is that correct? Or, is there a way to overwrite in XML?

By the way, all this is being done for bulk uploads / updates, so the only way to automate this (even in json) would be to overwrite if the 'handle' is the same. I cannot use overwrite based on ID, because while creating products - I will not know what the ID is. The only information I have is the handle, and ideally - while creating the product what I want to do is - if handle exists then overwrite, if new handle then create. (similar functionality to the manual csv import function)

What is the best way to go about this? (for now - in xml, but certainly in json as well?)

Thanks again!
