I am searching and trying to update the eBay store price using the eBay API. I have the App ID DevID and cart ID. I have been trying to update the price using the API. I went through the documentation of eBay API. But couldn't find any proper solution.
Is there any script in PHP that can help me?
The easiest way ito update price and quantity s to use ReviseInventoryStatus API. Just need to supply ItemID and price
Then to build procedure you can browse SO:

If you only need to update price/quantity Isuggest you not to use any SDK.
