We have an ETL system that can query or push data to venders (e.g. Paypal, Authorize.net, ShipStation, even USPS). I am wanting to setup Shopify to access a Store (configured client access) and to get orders for reporting.
My first step is getting authentication to work with a simple API all from a windows console (host) application (used within the ETL system). All seems straight forward until I read the documentation (i.e. https://shopify.dev/docs/apps/build/authentication-authorization/get-access-tokens/exchange-tokens) on authenticating and see I have required fields for "subject_token" and "subject_token_type". For my ETL API calls, I will not have such a token.
Question: Are these APIs strictly to be used within hosted web applications? How can I use the APIs within a simple console application on a Windows server? Thank you in advance.
If anyone can direct me on what I am missing it is greatly appreciated. I have downloaded the .NET ShopifySharp solution and reviewed the authorization code part. It does not seem to follow the documention in that a "code" parameter is being passed. The code parameter is defined as, "The authorization code generated by Shopify, which should be a parameter named 'code' on the request querystring.", and I am not sure where to get this code value.
I have executed the access API in postman and do get the following error. But, again, don't know where I need to gather this information.
{
"error": "missing_subject_token",
"error_description": "Missing subject token and/or subject token type in token exchange request."
}
