Power BI REST API is a service endpoint that supports a series of HTTP commands (GET, POST, PUT, DELETE), enabling the interaction with Power BI programmatically. This means you can integrate Power BI reports, dashboards, and datasets into applications using these APIs, making it a powerful automation tool.

For instance, using Power BI REST API, you can push data into a dataset, refresh a dataset, programmatically download Power BI reports, or even create a new workspace.

Table of Contents

Example:

Let’s take an example where we want to push data into a Power BI dataset using the ‘POST rows’ API method:

POST https://api.powerbi.com/v1.0/myorg/datasets/{datasetId}/tables/{tableName}/rows

In this process, you should replace `{datasetId}` and `{tableName}` with the ID of the dataset and the name of the table you want to push data into. The JSON body will contain the data you want to push.

PowerShell cmdlets:

PowerShell cmdlets are lightweight commands that perform a specific function in the PowerShell environment. With respect to Power BI, PowerShell cmdlets can automate numerous tasks, such as uploading Power BI reports, adding users to a workspace, refreshing a dataset, etc.

Cmdlets are very useful for automating time-consuming or repetitive tasks, which makes them particularly suited for managing large-scale analytics solutions.

Example:

A simple example of this could be automating the task of refreshing a Power BI dataset. In PowerShell, you can refresh a dataset using the `Start-PowerBIDatasetRefresh` cmdlet as below:

Start-PowerBIDatasetRefresh -WorkspaceId “xxxxxx-xxxxx-xxxxx-xxxxx” -DatasetId “xxxxxx-xxxxx-xxxxx-xxxxx”

In the above, `-WorkspaceId` and `-DatasetId` parameters should be replaced with your Workspace ID and Dataset ID respectively.
