How to monitor the data in API portal?

Hello Team,

I have published an API. I have done the GET method using POSTMAN with APIKEY

The call is successful(200 OK) so I'm expecting the count to increase in the API portal but still the count is zero.

Also when I test the same in API Dev portal, I'm getting 401 (I have used API key as user and Secret as password)

Could anyone let me know what I'm missing here
