I have created a very basic private Shopify application to retrieve orders from eBay and push them to Shopify.
It works great! On ONE store.
Trying on a second store, the function to create a new order in Shopify just fails completely or reports incorrect credentials. BUT the syntax is EXACTLY the same.
Also, other calls work fine! For example, retrieving product inventory, using the same credentials.
I have a different API KEY and SECRET for each of the 2 stores. Again, 1 works fine - the other doesn;t.
I have set ALL permissions to read/write in desperation which I try to work this out.
WHAT IS HAPPENING? Someone please help me here, I just don't get it, this makes no sense, Shopfiy support are no help. And here I was thinking the Shopify REST API was nice and straightforward, easy to use... never easy. Any help is much appreciated.
I am using PHP.
