# Connect Your First Platform to Brandstack for Unified Data

> Learn how to connect Shopify, Meta Ads, and Google Ads to Brandstack via OAuth so you can start tracking unified performance and blended ROAS.

Brandstack pulls data from your storefronts and ad platforms into one place. We recommend starting with your primary e-commerce platform, such as Shopify, and then connecting the ad channels that drive traffic to it. This page walks you through the connection process step by step.

<Steps>
  <Step title="Go to the Integrations page">
    From the left sidebar, click **Integrations**, then choose **Add new source**.

  </Step>

  <Step title="Pick your platform">
    Select the platform you want to connect first. We suggest starting with your main storefront, then adding ad platforms afterward.

    Recommended order:

    1. Shopify (or your primary storefront)
    2. Meta Ads
    3. Google Ads
  </Step>

  <Step title="Click Connect and authorize">
    Click **Connect**. You will be redirected to the platform's OAuth sign-in page. Log in with the account that has admin access, review the permissions, and click **Allow**.
  </Step>

  <Step title="Choose accounts">
    After authorization, select the specific accounts, stores, or ad accounts you want Brandstack to access. You can add more later from the same integration page.

  </Step>

  <Step title="Wait for the initial backfill">
    Brandstack will start an initial backfill to import historical data. This usually completes within a few minutes, although large ad accounts may take up to an hour. You will see a status indicator on the Integrations page.
  </Step>
</Steps>

<Tip>
  Connecting both Meta Ads and Google Ads unlocks blended ROAS in your dashboard, so you can see true return on ad spend across channels in one number.
</Tip>

## What happens next

Once the backfill finishes, your data appears in the Brandstack dashboard. Repeat the steps above for each additional platform you want to connect.
