How to import grafana dashboard json file manually

I have exported the dashboard in json format.

I want to import the json file manually to create the same dashboard in new grafana instance.

While googling i got some related information but finding difficulties to implement successfully.

From the site http api link i got the code snippet like,

POST /api/dashboards/db HTTP/1.1
Accept: application/json
Content-Type: application/json
Authorization: Bearer eyJrIjoiT0tTcG1pUlY2RnVKZTFVaDFsNFZXdE9ZWmNrMkZYbk

“dashboard”: {
“id”: null,
“uid”: null,
“title”: “Production Overview”,
“tags”: [ “templated” ],
“timezone”: “browser”,
“schemaVersion”: 16,
“version”: 0
“folderId”: 0,
“overwrite”: false

The above code snippet looks like we can create new dashboard with existing json file but i have no idea of how to implement this code snippet successfully.

Some body guide me how to achieve this
