How can I insert JSON data directly elastic search using curl command?

I want to insert JSON data into elastic search directly using curl command data I am getting from one of the web service

curl -XPOST http://localhost:9200/index/doc -d 'YOUR JSON HERE`

I tried that data is loading properly but it's not visible in Discover tab of kibana, I think there is issue with timestamp do you know how to specify the time stamp

How can I tell? I have no idea of what you sent, what the mapping is, how you configured your index pattern in Kibana...

You should provide more details.
