Not able to post data to Splunk via postman

[rgudimalla007]

I am using this body:

{"time": "", "event":{"hello": "world"}}

postman Uri: "https://localhost:8088/services/collector"

local Splunk instance: "http://localhost:8000/en-GB/manager/search/http-eventcollector"

But I'm getting 

{

    "text": "No data",

    "code": 5

}

I am using Splunk 8.0.6, Please help!
