How to reply to a message via Community Api V2

TariqHussain, thanks for your message

As suggested I added the board Id in the Body

{
"data": {
"type": "message",
"subject": "hello world",
"body": "this is a message post.",
"parent" : "105",
"board": {
"id" : "health_and_fitness_club"
}}}

Got below Response, but still replies are not showing
