Accessing Order Collections

While I have shared the code above here is our use case :
We want to access Orders (Stores/Orders) periodically from a back-end server application with no UI. We want to do additional processing for our internal downstream application. Our current approach is to expose Stores/Orders collection using http-functions, which can be consumed by our back-end server to pull the Orders data. Please suggest if this is the right approach or is there any alternative approach.
