A client of mine wants to get Net_Sales, Gross_Sales, etc... from his locations on clover and use the data on google data studio. the script I'm writing for him runs on Google App Engine and will retrieve Net, gross sales, etc... every day and update the data to a SQL database which then the client connects to google data studio and generate reports. I've tested my script with a sandbox account and it works fine but when we test it on the production API endpoint using my client's token it gives a 401 error. the script isn't for public use so I can't publish it as an app on clover. so how can I do this on the production API endpoint?
