Integrate Hassio with Osiris water sensor

I am new to HA and have installed Hassio and already added several sensors, automations, cameras and all I could think of.

I am now trying to integrate Osiris water monitor Osiris API which has Restful APIs available which I’m trying to translate to Hassio.

I believe I should be using the Restful sensor Restful to achieve my goal of fetching Osiris readings, but struggling heavily to translate the following into the Restful sensor:

curl -i --tlsv1 -X POST “” -d ‘{ “email”: “[email protected]”, “password”: “api_password”, “procedure”: “Get_Full_Sensor_Data_And_Goals”, “args”: “774” }’ -H “Content-Type: application/json”
