JSON data to post on personnel web

can anybody help me to send JSON data to the personnel web page
i have personnel domain with cpanle with API key
from eps32 i can send data and can receive on web
how to do this using nodered ?

In what precise format does the esp32 send data to this web page?
What protocol does it use?

An example of this data would be useful, with the URL and API keys concealed of course.

Send your JSON (js object) in msg.payload to the http request node set to POST.

See this cookbook example
