n8n-nodes-powerbi

This package contains nodes for n8n that enable complete integration with Microsoft Power BI REST APIs. These nodes enable automation, integration, and orchestration of data flows with Power BI directly in n8n.

About the Author

This Community Node was created and made freely available by Anderson Rocha from Universo Automático for the community and was designed to simplify and abstract all the complexity of using Power BI APIs.

Authentication Methods

This node supports two authentication methods:

$3

- Use case: Applications acting on behalf of a user through interactive authentication flow
- Credential type: Power BI OAuth2 API
- Token management: Automatic refresh when tokens expire

$3

- Use case: Direct API integration with pre-obtained tokens
- Credential type: Power BI API
- Token management: Manual token management required

$3

In the node configuration:
1. Select Authentication type (OAuth2 or Bearer Token)
2. The appropriate credential field will appear automatically
3. Configure the matching credential type

$3

The Power BI node has been configured as an AI tool within n8n, allowing it to:

1. Be easily accessed by n8n's AI assistant
2. Be used in natural language-driven automations
3. Appear in the AI tools palette in the flow editor

Setting up the Application in Microsoft Entra ID (Azure AD)

To use the Power BI node with OAuth2 authentication, you need to register an application in Microsoft Entra ID (formerly Azure AD). Follow the steps below:

$3

1. Access the Azure Portal.
2. Navigate to Microsoft Entra ID > App registrations.
3. Click New registration.
4. Provide a name for the application, for example "n8n Power BI Integration".
5. In Supported account types, select Accounts in this organizational directory only.
6. In the Redirect URI section, select Web and enter: https://your-n8n-domain/rest/oauth2-credential/callback.
- For local development environment, use: http://localhost:5678/rest/oauth2-credential/callback
7. Click Register.

$3

1. In the registered application's side menu, click API permissions.
2. Click Add a permission.
3. Select Power BI Service.
4. You can choose between Delegated permissions (for OAuth2) or Application permissions (for Service Principal):

For delegated permissions (recommended for most cases):
- Dataset.Read.All
- Dataset.ReadWrite.All
- Report.Read.All
- Report.ReadWrite.All
- Dashboard.Read.All
- Dashboard.ReadWrite.All
- Workspace.Read.All
- Workspace.ReadWrite.All
- Content.Create
- Tenant.Read.All (for administrative functions)

For application permissions (Service Principal):
- Dashboard.Read.All
- Report.Read.All
- Dataset.Read.All
- Workspace.Read.All
- Tenant.Read.All

5. Click Add permissions.
6. If using Service Principal, you'll need to request an administrator to Grant admin consent for [your directory].

$3

1. In the side menu, click Certificates & secrets.
2. In the Client secrets section, click New client secret.
3. Add a description and select an expiration period.
4. Click Add.
5. IMPORTANT: Immediately copy the generated secret value, as it cannot be viewed again.

$3

Note the following values that will be needed to configure the node in n8n:

- Client ID: Found in Overview > Application (client) ID
- Client Secret: The value you copied when creating the client secret
- Tenant ID: Found in Overview > Directory (tenant) ID

Using the Node

$3

1. Add the Power BI node to your workflow.
2. Select Authentication Method: Choose between OAuth2 or Bearer Token
3. Configure Credentials:

#### For OAuth2 Authentication:
1. Create a "Power BI OAuth2 API" credential with:
- Client ID: The registered application ID
- Client Secret: The generated client secret
- Scope: Leave blank or use https://analysis.windows.net/powerbi/api/.default

#### For Bearer Token Authentication:
1. Create a "Power BI API" credential with:
- Bearer Token: Your API access token

4. Select Resource and Operation: Choose the desired resource (dashboard, report, dataset, etc.) and operation
5. Configure Parameters: Set operation-specific parameters as needed

Limitations and Troubleshooting

$3

- Rate limits: The Power BI API imposes rate limits that may vary depending on your license and subscription plan. Learn more
- Permissions: Many operations require administrative or owner permissions in the workspace
- Some operations require Premium license: Certain operations like programmatic refresh or DAX queries in large volumes may require Premium capacity
