I am trying to use the Rails *shopify_app* gem with a private API key. The documentation for the gem mentions that it's possible to do this but doesn't say how. The instructions are only for a Shopify Partner Account.
For a private api key there seems to be no way of specifying the return url. This results in the following response fragment being sent back:
{"error":"invalid_request","error_description":"The redirect_uri and application url must have matching hosts"}
I've looked around a bit but was not able to find a solution to this. It seems like this should be better documented on Shopify API wiki. I'd appreciate any help with this.
cheers,
