I created shopify public app using yarn create @Shopify/app. I get nodejs code template will oAuth process and session token. Following is the API that i created in shopify public app.
Now when I call this API in postman I get the following error
I am unable to find out that how to give shop name and where do I get shop name and access_token? And I wanted to ask that is it possible to call API which is created in shopify public app in other software? It would act as a third party integration. Kindly someone guide me.
