Getting Error 1001 Invalid Access Token. Check the value of authorization HTTP request header
Hi, I am trying to implement Inventory API for creating Inventory and adding an item to sell on eBay using eBay SDK with PHP. I tried with Sandbox as well as Production, but got the same error for both the try. I cross checked all the credentials and everything looks good. But yet, it didn't worked. I tried the to run the given sample example with my credentials and there I am getting the response for production. How can I get rid of these error ?
