POAS Data Feed power-up

The POAS Data Feed power-up lets you send actual profit to ad platforms and analytics tools through sGTM. Profit values are stored securely in Stape's storage and matched against your product catalogue when events arrive, so sensitive margin data never goes to the frontend.

POAS Data Feed is available on the Pro subscription plan and higher. To check your current plan or upgrade, go to your sGTM container settings.

1. Log in to your Stape account and select your sGTM container from the dashboard.

2. Go to Power-ups and click Use next to the POAS Data Feed panel.

3. Toggle the POAS Data Feed switch to enable it and click Save changes.

In this guide, we use Shopify and WordPress/WooCommerce examples. The same setup logic can also be used with other CMS platforms if you can export a feed with product IDs and margin values.

1. In your Stape container, go to Power-ups → POAS Data Feed.

2. Enable Auto Sync.

3. Paste the feed URL, set the CSV delimiter to comma, and choose a sync frequency. Click Next.

4. Map the columns.

4.1. Wordpress:

• Product ID → id column
• Value Type → Absolute
• Value → margin column

4.2. Shopify:

• Product ID → SKU column
• Value Type → Absolute, if the margin value comes from Cost per item
• Value → Margin column

Click Complete.

5. The catalogue downloads immediately and syncs automatically going forward.

1. In your sGTM container, go to Templates, and in the Variable Templates section click Search gallery.

2. Search for Stape Store Margin Lookup, and add it to your workspace.

3. Go to Variables, and in the User-Defined Variables section click New.

4. Create a new variable and select Stape Store Margin Lookup as the type.

5. Set the Product ID field to match the identifier used in your data layer (item_id for Wordpress and item_sku for Shopify).

6. Tick all options under More settings unless your tracking logic requires otherwise. Click Save.

Add the Stape Store Margin Lookup variable as the conversion value in your platform tags. For example, in the GA4 tag set it as Event Parameter:

1. 1.
   Add a new parameter named value (or any custom name you want to use in GA4 reports, e.g. profit).
2. 2.
   Set its value to your Stape Store Margin Lookup variable.

To verify the setup is working:

1. Open Preview in your sGTM container.

2. Trigger a purchase event on your site.

3. In the Tag Manager Debug Mode window, locate the triggered tag.

4. Under Tag details, check the Parameters to Add / Edit, the value will show your POAS.

A sample scenario is an eCommerce store that wants to optimize ad spend based on actual profit rather than revenue. Their Google Ads campaigns are generating strong ROAS, but after accounting for product costs and fees, several top-performing campaigns are actually unprofitable.

You can identify this problem and fix it this way:

1. 1.
   Compare your Google Ads ROAS against your actual profit margins for the same period. If Google Ads reports a 4x ROAS on a product that costs you $60 to produce and sell for $95, the real return may be far lower once costs are factored in.
2. 2.
   Enable POAS Data Feed and configure it with your product margins. This sends the margins to Google Ads instead of revenue when a purchase event fires.
3. 3.
   Monitor your Google Ads campaigns using the profit-based conversion value over the same time window and compare it against the revenue-based value.

If your campaigns were previously optimizing toward high-revenue but low-margin products, you should see Google Ads begin shifting budget toward products with higher actual profit after the learning period.
