Power BI is a Business Intelligence (BI) tool offered by Microsoft that provides you with real-time high-level analytics, extensive modeling, and custom development. It has led the charge in making business analysis more efficient through services that are intuitive, interactive, and easy to use.
REST API is defined as a Software Architectural Style built to guide the development and design of the architecture for the World Wide Web. REST APIs define a set of constraints for how the architecture of a distributed system should behave.
This blog talks about the different methods you can use to establish REST API Power BI Integration. It also gives a brief introduction to the concept of REST API & Power BI and the benefits of integrating the two.

What is a REST API?
REST APIs provide a flexible, lightweight way of integrating applications. REST APIs allow you to search for some items, and then the results will be returned from the service you initiated the request from. A REST API has the following components:
- The Headers: Headers refer to the authentication mode and the content types.
- The Method: There are various methods you can use to call a REST API, the most common ones being POST and GET. The GET method is used to gather information while the POST method can be used to send information to the resources on the web.
- The Endpoint: The Endpoint is defined as the URL of the resource to which you are going to place the requests. For instance, https://api.powerbi.com/v1.0/myorg/.
- The Data or Body: This refers to the textual data in the form of JSON, which needs to be sent to the resource.
To securely access the Power BI REST API, you will first have to request an embed token using which you can call the APIs and execute your functions. In the first method, you will be looking at how to authorize an application and call the APIs through Postman.
Postman is a free tool that allows you to make POST or GET calls to various URLs which are then saved in a collection.
Here are a few REST design principles that are integral for the smooth functioning of a REST API:
- Client-Server Decoupling: In REST API design, Server and Client applications must be completely independent of each other. The only information available to the client-side should be the URI of the requested resource. Similarly, a server application shouldn’t change the client application other than passing it to the requested data through HTTP.
- Statelessness: REST APIs are Stateless. This means that each request should contain all the information required to process the It. This can also mean that REST APIs don’t require any server-side sessions. Server applications aren’t permitted to store any data related to the client request.
- Cacheability: Whenever possible, resources should be Cacheable on the Server or Client-side. Server responses should also contain information about whether caching is allowed for the delivered resource. You should aim for improving performance on the client side while increasing scalability on the server side.
- Uniform Interface: All API requests for the same resource should look the same, irrespective of where the request comes from. The REST API should ensure that the same piece of data, like the email address or name of a user, belongs to only one Uniform Resource Identifier (URI). Resources shouldn’t be too huge but should contain every piece of information that the client may need.
- Layered System Architecture: In REST APIs the responses and calls go through different layers. You shouldn’t assume that the Client and Server applications connect directly to each other. There may be various intermediaries involved in the communication loop.
Therefore, REST APIs need to be designed so that neither the server nor the client can tell whether it communicates with an intermediary or an end application.
What is Power BI?
Power BI helps create a data-driven culture in the workplace, providing self-service analytics at the enterprise scale for every employee of your organization.
Power BI is a suite consisting of several components that house intuitive features for Data Visualizations, Dashboarding, and Reporting to name a few. Here are a few key benefits of Power BI that make it an indispensable tool in the workplace:
- Great Accessibility: Power BI provides you with advanced accessibility with its ability to run through remote apps on several Internet platforms and devices like iOS, Android, and Windows to name a few.
- Key Functionalities: Power BI provides drag-and-drop functionality that lets you generate customized reports swiftly. It also provides the option of digging further into the data visualizations to help understand the data better. The usage of Natural Language Queries means that the users don’t have to spend time trying to learn a complex query language.
- Embeddable Attributes: It provides users the ability to embed Business Intelligence and Analytics seamlessly. You can build fully customized reports and dashboards to better suit your business use cases and data requirements.
- Connectivity: Power BI supports several data sources, for instance, the Financial data collected from your company’s ERP or the Sales data from the CRM. By providing access to Azure Cloud, On-premise, and third-party data sources, you can create new datasets from a wider range of disparate sources.

The Methods Used for REST API Power BI Integration
Here are the methods you can use to establish REST API Power BI connection seamlessly:
Method 1: Using Power BI Developer Portal for REST API Power BI Integration
Here are the steps involved in setting up Power BI REST API Data Source connection:
Step 1: Register an Application for Power BI
- Once you’ve signed in with your account credentials, you’ll see your name appear under Step 1. Click on the Next button to continue the process of REST API Power BI Integration.
- Next, you need to register the application. Give an Application Name for the app and choose an application type. There are two kinds of applications- Server-side and Native.
- This method will shed light on the Server-side web application. Enter a Redirect URL and Home Page URL, as mentioned below:
- If you scroll down, you can see that there are various API access permissions that you need to define your app with for the REST API Power BI Integration.
- Since you are going to read the resources, give the basic read access required for reading the datasets, reports, workspaces, and dashboards in the account.
- Click on the Register button when done with this step of REST API Power BI Integration.
- Once you’ve clicked on Register, the app will be created and you will get an Application Secret and an Application Key.
- Copy them both to a secure location since you will be needing this in your next steps while calling the Power BI REST API.
Step 2: Authorize User
- The next step in REST API Power BI Integration is to authorize the user to the application.
- You need to use the Application ID and retrieve the Access Token for this. You will be utilizing this Access Token in the next step to call the other APIs.
- To authorize the user, you need to allow the user to sign in to the app and retrieve the token. But first, you need to prepare the sign-in URL. It accepts parameters like Scope, State, ResponseMode, ClientID, ResponseType, and RedirectURI.
- Paste the URL in the browser and hit enter. You can see a dialog box that displays the user consent required by the application to allow the required permissions.
- Click on Accept to continue the REST API Power BI Integration process.
- Once the user is authorized, the user will be redirected to the Redirect URI mentioned in the API request. Usually, this request has a code in it that can be used as the authorization method for securely calling APIs.
- But since you don’t have any web application running on your web host, you will receive an error code like the below.
- In the Requested URL section, there is some text after the word code. Copy it and store it securely somewhere for the REST API Power BI Integration process.
Step 3: Generate Access Token
- Once you’ve obtained the code, generate the Access Token. To generate the Access Token, you need to call an endpoint using the POST method with specific information that will return the Access Token.
- In the Resource URL, pass the following fields as the body of the request. You can use Postman to call the endpoint for the REST API Power BI Integration process.
- When you call the aforementioned endpoint, the results are returned as follows. The access_token is the value that you need to use while calling the Power BI REST API. Copy and store the value of the Access Token in a secure location.
Step 4: List of Reports
- Call the Power BI REST API and fetch the details as you need. Suppose, you’re trying to get a list of all the reports in your personal workspace. The endpoint to fetch the list of reports is https://api.powerbi.com/v1.0/myorg/reports.
- To call this endpoint, you need to pass the Access Token as an authorization method in the header of the GET request. You can look at the figure below and generate your GET request:
Step 5: List of Datasets
