sendData not work properly also void sendData also

I moved your new topic here. Don't double post / create more topics for your question. Keep everything in one thread.

Are you using an ESP32? It looks like the libraries have changed. For example "HttpClient" is now "HTTPClient".

Start over with File -> Examples -> ESP32 -> HTTPClient -> BasicHttpClient

ok sir i have proper in httpclient libraries but sendData function not enable why? can you help me

Did you "Start over with File -> Examples -> ESP32 -> HTTPClient -> BasicHttpClient"?
