Integrating API Callback function into Plotly Dash

Hi,
I’m fairly new to python and plotly dash
I’m trying to develop a dashboard with 3 inputs and 4 outputs.
The 3 inputs will be used for a function - wherein I’m using an API Call and the resulting json will be used for the output generation.
When I tried using something like “call_api_function(date, option_selected)” in my app callback section, I could just see the kernel being processed with no output
Can someone help me?

Thanks!
