Step by Step Guide to Building a Microsoft Power BI API Integration in Go

Aug 7, 2024 • 6 minute read

Hey there, fellow developer! Ready to dive into the world of Power BI and Go? Let's build something awesome together. We'll be using the armpowerbiembedded package to create a slick integration that'll make your data visualization dreams come true.

Prerequisites

Before we jump in, make sure you've got:

Go installed (you're a Go dev, right?)
An Azure subscription (if you don't have one, now's the time!)
A Power BI Pro license (because we're pros here)
The right permissions (you know, the usual admin stuff)

Setting Up Your Project

First things first, let's get our project off the ground:

mkdir power-bi-go-integration
cd power-bi-go-integration
go mod init github.com/yourusername/power-bi-go-integration

Now, let's grab the packages we need:

go get github.com/Azure/azure-sdk-for-go/sdk/azidentity
go get github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/powerbiembedded/armpowerbiembedded

Authentication: The Key to the Kingdom

Head over to the Azure portal and create a new Azure AD application.
Jot down your client ID, client secret, and tenant ID.
Now, let's authenticate like pros:

import (
    "github.com/Azure/azure-sdk-for-go/sdk/azidentity"
)

cred, err := azidentity.NewClientSecretCredential(tenantID, clientID, clientSecret, nil)
if err != nil {
    log.Fatal(err)
}

Initializing the Power BI Client

Time to bring in the big guns - the Power BI client:

import (
    "github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/powerbiembedded/armpowerbiembedded"
)

client, err := armpowerbiembedded.NewCapacitiesClient(subscriptionID, cred, nil)
if err != nil {
    log.Fatal(err)
}

Basic API Operations

Let's flex those API muscles:

Listing Workspaces

pager := client.NewListPager(nil)
for pager.More() {
    page, err := pager.NextPage(context.Background())
    if err != nil {
        log.Fatal(err)
    }
    for _, capacity := range page.Value {
        fmt.Printf("Capacity: %s\n", *capacity.Name)
    }
}

Retrieving Reports and Generating Embed Tokens

For these operations, you'll need to use the Power BI REST API. The armpowerbiembedded package focuses on capacity management, so we'll need to make HTTP requests for reports and embed tokens.

Embedding Power BI Content

Now for the fun part - let's embed some content!

Create an HTML template:

<!DOCTYPE html>
<html>
<head>
    <title>Power BI Embed</title>
    <script src="https://cdn.powerbi.com/powerbi-client/powerbi.min.js"></script>
</head>
<body>
    <div id="reportContainer"></div>
    <script>
        // We'll add our embedding code here
    </script>
</body>
</html>

Add the JavaScript for embedding:

var embedConfiguration = {
    type: 'report',
    tokenType: models.TokenType.Embed,
    accessToken: 'YOUR_EMBED_TOKEN',
    embedUrl: 'YOUR_REPORT_EMBED_URL',
    settings: {
        filterPaneEnabled: false,
        navContentPaneEnabled: false
    }
};

var report = powerbi.embed(reportContainer, embedConfiguration);

Error Handling and Best Practices

Always check for errors and handle them gracefully. And remember, with great power comes great responsibility - respect those API rate limits!

if err != nil {
    // Log the error, maybe retry the operation, or gracefully degrade functionality
    log.Printf("An error occurred: %v", err)
}

Testing Your Integration

Fire up your Go application and watch your Power BI content come to life in your web browser. If all goes well, you should see your embedded report. If not, don't sweat it - debugging is half the fun!

Wrapping Up

And there you have it! You've just built a Power BI integration with Go. Pretty cool, right? This is just the beginning - there's so much more you can do with Power BI and Go.
