Microsoft Power BI API Authentication

How to authenticate Microsoft Power BI API requests: one Bearer API key plus a connectionId. MindCloud runs the OAuth flow and refreshes tokens for you.

Every Microsoft Power BI API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your Microsoft Power BI account. This page covers both, plus exactly how to send them, so you do not need to visit any other page to get authenticated.

Steps to authenticate

Create a MindCloud account at app.mindcloud.co if you do not already have one.
Generate a MindCloud API Key in API Keys. This is the Bearer token you send on every request. Keep it on your server.
Create a Microsoft Power BI connection in Connections. Microsoft Power BI uses OAuth. When you create the connection, you are redirected to sign in to Microsoft Power BI and approve access — MindCloud stores the resulting tokens and refreshes them automatically, so your integration never has to.
Copy the connection’s connectionId — you will send it on every request alongside your MindCloud API Key.

How requests are authenticated

Authentication has two layers. Your MindCloud API Key authenticates the request to MindCloud, sent as a Bearer token in the Authorization header. The connectionId selects the connected Microsoft Power BI account that should run the action. MindCloud stores and refreshes the Microsoft Power BI credentials behind that connection, so you never send provider tokens with your requests.

Pass connectionId in the query string for GET and DELETE actions, and in the JSON body for POST, PUT, and PATCH actions.

For example, calling List Workspaces with an Microsoft Power BI connection looks like this:

curl --request POST \
  --url "https://connect.mindcloud.co/v2/universal/apps/microsoftPowerBI/actions/list-workspaces/run" \
  --header "Authorization: Bearer $MINDCLOUD_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
  "connectionId": "$CONNECTION_ID",
  "arguments": {}
}'

The Authorization: Bearer <your MindCloud API Key> header authenticates you to MindCloud; the connectionId tells MindCloud which Microsoft Power BI account to run the action against. Missing or invalid Authorization returns 401, and a missing or mismatched connectionId returns 400.

Set up Microsoft Power BI OAuth

You need a work or school Microsoft account that can open the Power BI service and permission to register an app in Microsoft Entra.

Confirm you can open the Power BI service
Sign in to Power BI in a browser with your work or school account. If self-service is enabled, Microsoft can assign the initial license the first time you open the service.
Register a Microsoft Entra app
In the Microsoft Entra admin center, open App registrations and create a new app registration for this Power BI connection.
Microsoft Entra admin center → App registrations
Add your redirect URI
Open the app registration authentication settings and add the web redirect URI that MindCloud shows for this connection.
Create a client secret
Open Certificates & secrets in the app registration and create a new client secret. Copy the secret value now because Microsoft shows it only once.
Grant Power BI delegated permissions
Add the delegated Power BI API permissions required for the actions you want to use, then grant admin consent if your tenant requires it.

Keep your key safe

Keep your MindCloud API Key on your server; do not ship it in browser code, mobile apps, public repositories, or logs. Anyone with the key can call the Universal API as your MindCloud account, across every connection you have created.
