If you have to send data from esp32 to your hosted website its kind of tricky one .Since esp32 is local hosted it is only accessible in your local network or you port forward it if you have static ip from your service provider. I 'll suggest if you can host API or websocket or any other medium you can make esp32 as client and can connect to the website and feed their data but as ESP32 as server is kind trouble one .
Can you tell me what you are trying to accomplish may be i can give you some alternative ideas
