Create a data source

POST /api/datasources

Example Graphite Request:

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

{
  "name":"test_datasource",
  "type":"graphite",
  "url":"http://mydatasource.com",
  "access":"proxy",
  "basicAuth":false
}

Example Graphite Response:

HTTP/1.1 200
Content-Type: application/json

{
  "datasource": {
    "id": 1,
    "orgId": 1,
    "name": "test_datasource",
    "type": "graphite",
    "typeLogoUrl": "",
    "access": "proxy",
    "url": "http://mydatasource.com",
    "password": "",
    "user": "",
    "database": "",
    "basicAuth": false,
    "basicAuthUser": "",
    "basicAuthPassword": "",
    "withCredentials": false,
    "isDefault": false,
    "jsonData": {},
    "secureJsonFields": {},
    "version": 1,
    "readOnly": false
  },
  "id": 1,
  "message": "Datasource added",
  "name": "test_datasource"
}

Note: By defining password and basicAuthPassword under secureJsonData Grafana encrypts them securely as an encrypted blob in the database. The response then lists the encrypted fields under secureJsonFields.

Example Graphite Request with basic auth enabled:

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

{
  "name": "test_datasource",
  "type": "graphite",
  "url": "http://mydatasource.com",
  "access": "proxy",
  "basicAuth": true,
  "basicAuthUser": "basicuser",
  "secureJsonData": {
    "basicAuthPassword": "basicpassword"
  }
}

Example Response with basic auth enabled:

HTTP/1.1 200
Content-Type: application/json

{
  "datasource": {
    "id": 1,
    "orgId": 1,
    "name": "test_datasource",
    "type": "graphite",
    "typeLogoUrl": "",
    "access": "proxy",
    "url": "http://mydatasource.com",
    "password": "",
    "user": "",
    "database": "",
    "basicAuth": true,
    "basicAuthUser": "basicuser",
    "basicAuthPassword": "",
    "withCredentials": false,
    "isDefault": false,
    "jsonData": {},
    "secureJsonFields": {
      "basicAuthPassword": true
    },
    "version": 1,
    "readOnly": false
  },
  "id": 102,
  "message": "Datasource added",
  "name": "test_datasource"
}

Example CloudWatch Request:

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

{
  "name": "test_datasource",
  "type": "cloudwatch",
  "url": "http://monitoring.us-west-1.amazonaws.com",
  "access": "proxy",
  "jsonData": {
    "authType": "keys",
    "defaultRegion": "us-west-1"
  },
  "secureJsonData": {
    "accessKey": "Ol4pIDpeKSA6XikgOl4p",
    "secretKey": "dGVzdCBrZXkgYmxlYXNlIGRvbid0IHN0ZWFs"
  }
}

Update an existing data source

PUT /api/datasources/:datasourceId

Example Request:

PUT /api/datasources/1 HTTP/1.1
Accept: application/json
Content-Type: application/json
Authorization: Bearer eyJrIjoiT0tTcG1pUlY2RnVKZTFVaDFsNFZXdE9ZWmNrMkZYbk

{
  "id":1,
  "orgId":1,
  "name":"test_datasource",
  "type":"graphite",
  "access":"proxy",
  "url":"http://mydatasource.com",
  "password":"",
  "user":"",
  "database":"",
  "basicAuth":true,
  "basicAuthUser":"basicuser",
  "secureJsonData": {
    "basicAuthPassword": "basicpassword"
  },
  "isDefault":false,
  "jsonData":null
}

Example Response:

HTTP/1.1 200
Content-Type: application/json

{
  "datasource": {
    "id": 1,
    "orgId": 1,
    "name": "test_datasource",
    "type": "graphite",
    "typeLogoUrl": "",
    "access": "proxy",
    "url": "http://mydatasource.com",
    "password": "",
    "user": "",
    "database": "",
    "basicAuth": true,
    "basicAuthUser": "basicuser",
    "basicAuthPassword": "",
    "withCredentials": false,
    "isDefault": false,
    "jsonData": {},
    "secureJsonFields": {
      "basicAuthPassword": true
    },
    "version": 1,
    "readOnly": false
  },
  "id": 102,
  "message": "Datasource updated",
  "name": "test_datasource"
}

Note: Similar to creating a data source, password and basicAuthPassword should be defined under secureJsonData in order to be stored securely as an encrypted blob in the database. Then, the encrypted fields are listed under secureJsonFields section in the response.
