[SOLVED] Updating Dx pin's through blynk cloud URL is not working

i am trying to make the built in led to ON through below URL
http://188.166.206.43/XXXXXX/update/D0?value=1

but it never effected ,i also tried with D2 but no effect.

NOTE: it works with virtual pins

hardware: NodeMCU

After doing little R&D i came to know that we have to use GPIO pin number …like D16 for built in LED.
