PowerBI-Node

Node SDK and client library for the Power BI Embedded REST APIs.

Installation

npm install powerbi-api

Usage

Creating a new client requires referencing the Power BI SDK as well as the Microsoft Rest Client. For an example of the Node SDK in action see the Power BI Node CLI.

var powerbi = require('powerbi-api');
var msrest = require('ms-rest');

var credentials = new msrest.TokenCredentials('{AccessKey}', "AppKey");
var client = new powerbi.PowerBIClient(credentials);

// Example API call
client.workspaces.getWorkspacesByCollectionName('{WorkspaceCollection}', function(err, result) {
    // Your code here
});

APIs

The following APIs groups are available:

• Datasets
• Gateways
• Imports
• Reports
• Workspaces

PowerBI API Calls

All API calls use the AppKey to authenticate the API calls. The AppKey can be retreived from Azure portal. Each API call sets the following HTTP header:

• Authorization: AppKey {AccessKey}

WARNING - Never expose your access keys client side in your application. If your access key is compromised a malicious user can take over control of your workspace collection. Access keys can be re-generated for your workspace collection within the Azure portal.

Creating Embed Tokens

Power BI Embedded uses embed token, which are HMAC signed JSON Web Tokens. The tokens are signed with the access key from your Azure Power BI Embedded workspace collection. Embed tokens are used to provide read only access to a report to embed into an application.

Required Claims

• ver: 0.2.0
• wcn: {WorkspaceCollectionName}
• wid: {WorkspaceId}
• rid: {ReportId}
• aud: https://analysis.windows.net/powerbi/api
• nbp: Token valid not before in Unix EPOCH time
• exp: Token expiration in Unix EPOCH time

var powerbi = require('powerbi-api');
var token = powerbi.PowerBIToken.createReportEmbedToken('{WorkspaceCollection}', '{workspaceId}', '{reportId}');

var jwt = token.generate('{AccessKey}');
