This article is part of a step-by-step walkthrough to push data into a dataset.
In step 4 of Push data into a dataset, Get a dataset to add rows into a Power BI table, you used the Get Datasets operation and Newtonsoft.Json to get a dataset id. In this step, you use the dataset id with the PostRows operation to add rows to a Power BI dataset.
When you call the PostRows operation, you add rows to a dataset.
Here's how to add rows to a dataset using the Power BI API.
Add rows to a Power BI table
Note
Before you get started, make sure you have followed the previous steps in the push data into a dataset walkthrough.
- In the Console Application project you created in Step 2: Walkthrough to push data, Get an authentication access token, add the code below.
- Run the Console App, and login to your Power BI account. You should see Rows Added in the Console Window. You can also login to Power BI to see the rows added to the dataset.
Sample push data into a dataset
Add this code into Program.cs.
In static void Main(string[] args):
static void Main(string[] args) { //Get an authentication access token token = GetToken(); //Create a dataset in Power BI CreateDataset(); //Get a dataset to add rows into a Power BI table string datasetId = GetDataset(); //Add rows to a Power BI table AddRows(datasetId, "Product"); }Add an AddRows() method:
#region Add rows to a Power BI table
private static void AddRows(string datasetId, string tableName)
{
string powerBIApiAddRowsUrl = String.Format("https://api.powerbi.com/v1.0/myorg/datasets/{0}/tables/{1}/rows", datasetId, tableName);
//POST web request to add rows.
//To add rows to a dataset in a group, use the Groups uri: https://api.powerbi.com/v1.0/myorg/groups/{group_id}/datasets/{dataset_id}/tables/{table_name}/rows
//Change request method to "POST"
HttpWebRequest request = System.Net.WebRequest.Create(powerBIApiAddRowsUrl) as System.Net.HttpWebRequest;
request.KeepAlive = true;
request.Method = "POST";
request.ContentLength = 0;
request.ContentType = "application/json";
//Add token to the request header
request.Headers.Add("Authorization", String.Format("Bearer {0}", token));
//JSON content for product row
string rowsJson = "{\"rows\":" +
"[{\"ProductID\":1,\"Name\":\"Adjustable Race\",\"Category\":\"Components\",\"IsCompete\":true,\"ManufacturedOn\":\"07/30/2014\"}," +
"{\"ProductID\":2,\"Name\":\"LL Crankarm\",\"Category\":\"Components\",\"IsCompete\":true,\"ManufacturedOn\":\"07/30/2014\"}," +
"{\"ProductID\":3,\"Name\":\"HL Mountain Frame - Silver\",\"Category\":\"Bikes\",\"IsCompete\":true,\"ManufacturedOn\":\"07/30/2014\"}]}";
//POST web request
byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(rowsJson);
request.ContentLength = byteArray.Length;
//Write JSON byte[] into a Stream
using (Stream writer = request.GetRequestStream())
{
writer.Write(byteArray, 0, byteArray.Length);
var response = (HttpWebResponse)request.GetResponse();
Console.WriteLine("Rows Added");
Console.ReadLine();
}

Although, we specify that we //Get the first id in the code above, the correct thing to do is search the dataset by name.
