Power BI API Essential Guide

What type of API does Power BI provide?

Based on the search results provided, Power BI does not appear to use REST, GraphQL, or SOAP APIs specifically. The search results do not contain any information about Power BI's API type.

To answer this question accurately, we would need additional information about Power BI's API architecture. Without that, I cannot definitively state what type of API Power BI uses.

However, I can provide some general information about API types that may be helpful:

Common API Types

  1. REST (Representational State Transfer):

    • Uses standard HTTP methods
    • Typically uses JSON for data exchange
    • Good for simple resource-driven applications
  2. SOAP (Simple Object Access Protocol):

    • Uses XML for message format
    • Often used in enterprise environments
    • Provides strong security features
  3. GraphQL:

    • Query language for APIs
    • Allows clients to request exactly the data they need
    • Good for complex data requirements and reducing over-fetching
  4. gRPC:

    • High-performance RPC framework
    • Uses protocol buffers
    • Designed for efficiency in data exchange

To determine which API type Power BI uses, you would need to consult Power BI's official documentation or developer resources. Different components of Power BI may potentially use different API types depending on their specific functions and requirements.

Does the Power BI API have webhooks?

The official Power BI API does not appear to have native webhook functionality. For real-time data streaming into Power BI, the recommended approach is to use the "Real-time streaming in Power BI" feature. This allows pushing data into Power BI datasets and reports in real-time, but is not the same as webhooks.

For integration scenarios, Microsoft recommends using Azure Functions or creating custom services to consume data from Power BI. This allows building webhook-like functionality, but requires custom development.

The Power BI JavaScript API does provide some event handling capabilities for embedded reports and dashboards, such as loaded, dataSelected, buttonClicked, dataHyperlinkClicked, and saved. However, these are client-side events for embedded content, not server-side webhooks.

For server-side integrations, Microsoft recommends using the Power BI REST APIs to pull data or trigger refreshes programmatically.

In summary, while Power BI offers various integration options, it does not have a native webhook system like some other platforms. Developers need to build custom solutions using the available APIs and services to achieve webhook-like functionality with Power BI.

Rate Limits and other limitations

Here are the key points about the API rate limits for the Power BI API:

General Limits

  • Power BI uses throttling to maintain optimal performance and reliability [3].

  • There are limits on the number of API calls that can be made within a time window per user [3].

  • The specific limits vary depending on the API endpoint and license type.

Specific Limits

  • For many API endpoints, there is a limit of 200 requests per hour per user [1].

  • However, some endpoints have different limits. For example:

    • The "GET /admin/datasets/{datasetId}/datasources" endpoint recently had its limit reduced to 50 requests per hour [1].
  • For push datasets, there are very limited capabilities designed only for near real-time streaming scenarios [2].

Other Considerations

  • There is no way to increase the API limits by upgrading licenses or moving to premium capacity [3].

  • The limits are per user and cannot be pooled at the environment or tenant level [3].

  • Exceeding the limits can result in 429 (Too Many Requests) errors [3].

  • Microsoft recommends using the scanner APIs as an alternative to access data source information if hitting limits [1].

Best Practices

  • Design applications to work within the published API limits.

  • Use batching and other optimization techniques to reduce the number of API calls needed.

  • Monitor API usage to stay within limits.

  • Consider using alternative APIs (like scanner APIs) for high-volume scenarios.

It's important to note that API limits can change, as evidenced by the recent change to the datasources endpoint. Developers should check the official documentation for the most up-to-date information on specific endpoint limits.

Latest API Version

Based on the search results provided, the most recent version of the Power BI API appears to be:

Version 4.20.0

This information comes from the NuGet package listing for Microsoft.PowerBI.Api [4].

Key points to consider:

  • This version number (4.20.0) refers specifically to the Microsoft.PowerBI.Api NuGet package, which provides .NET client libraries for interacting with the Power BI REST API.

  • The Power BI API itself may have a different versioning scheme than this client library package.

  • For the most up-to-date and authoritative information on Power BI API versions, it's recommended to check the official Microsoft Power BI documentation.

It's worth noting that the search results don't provide direct information about the Power BI API version itself, but rather about related components like Power BI Desktop and Power BI Report Server. These components have their own version numbers which may not directly correspond to the API version.

For developers working with Power BI:

  • Always refer to the official Microsoft documentation for the most current API information.
  • When using the Microsoft.PowerBI.Api package, check for the latest version on NuGet to ensure you have the most recent features and bug fixes.
  • Be aware that different components of the Power BI ecosystem (Desktop, Report Server, API, etc.) may have different version numbers and release cycles.

How to get a Power BI developer account and API Keys?

1. Sign up for a Power BI account

  • Go to powerbi.microsoft.com and sign up for a Power BI Pro account if you don't already have one. You may be able to get a free trial.

2. Register an application in Azure AD

  • Go to the Azure portal (portal.azure.com) and register a new application in Azure Active Directory. This will give you an Application ID and secret to use for authentication.

  • When registering, set the redirect URI to your application's URL where you want to receive the auth code.

  • Under API permissions, add the Power BI Service APIs you need access to.

3. Get authorization

  • Use the Application ID to request authorization from the user via OAuth 2.0. This will provide an authorization code.

4. Get an access token

  • Exchange the authorization code for an access token by making a POST request to the token endpoint.

5. Call Power BI APIs

  • Use the access token in the Authorization header when making API calls to Power BI.

What can you do with the Power BI API?

Based on the provided information, here are the key data models you can interact with using the Power BI API and what is possible for each:

Semantic Models (Datasets)

  • Create, read, update, and delete semantic models

Additionally, some advanced data modeling features may require using the XMLA endpoint rather than the REST API.
