Hi. I'm developing a mobile application for a shopify store and I'm working on creating orders. I'm having some trouble with the Orders API. Every time I try to create an order with an HTTP POST request I get back this message. I understand that the person who provided me with the API keys should give me write access to orders, but we can't figure out how...
Assuming the API key is a private app key, here are the details on how to setup and choose access scopes for such a key - https://help.shopify.com/en/api/getting-started/authentication/private-authentication
