# Step 4: Validate End-to-End Delivery

> Confirm the complete pipeline works — from storefront event to Upstack dashboard to a matched conversion in Meta Events Manager.

You've installed the pixel, verified events, and connected Meta CAPI. Now run a single end-to-end test to confirm the full pipeline is working: a storefront action should flow through Upstack and arrive as a matched conversion in Meta.

## What You'll Accomplish

Trigger a real event on your Shopify store and trace it through every stage — from the Upstack Live Event Stream to Meta Events Manager — confirming that server-side conversion data is being delivered correctly.

## Prerequisites

<Info>
  **Prerequisites:**

  * An active Shopify store
  * The Upstack Data app installed from the Shopify App Store
  * Your Pixel ID (found in the Upstack dashboard under Settings → Pixel)
</Info>

You should have completed [Step 3: Connect a Destination](/get-started/connect-a-destination).

## Validation Steps

<Steps>
  <Step title="Prepare your test environment">
    Open three tabs:

    1. **Upstack Dashboard** — navigate to **Events → Live Event Stream**
    2. **Meta Events Manager** — navigate to **Your Pixel → Test Events** and enter your storefront URL
    3. **Your Shopify storefront** — use an incognito/private window for a clean session

    <Info>
      Using Meta's **Test Events** tab gives you real-time visibility into incoming server events. Events in Test Events show within seconds, while the main Overview tab can have a 20+ minute delay.
    </Info>
  </Step>

  <Step title="Trigger a test purchase or add-to-cart">
    On your Shopify storefront, perform a complete flow:

    1. Visit a product page (generates `ViewContent`)
    2. Add the product to cart (generates `AddToCart`)
    3. Begin checkout (generates `InitiateCheckout`)
    4. If possible, complete a test purchase using Shopify's [Bogus Gateway](https://help.shopify.com/en/manual/checkout-settings/test-orders) (generates `Purchase`)

    <Tip>
      If you can't complete a test purchase, an `AddToCart` event is sufficient to validate the pipeline. The key is confirming the event appears in both Upstack and Meta.
    </Tip>
  </Step>

  <Step title="Confirm the event in Upstack">
    Switch to the Upstack Live Event Stream tab. Within a few seconds, you should see the events you just triggered. Click on an event to expand it and verify:

    * **Event type** matches your action (`AddToCart`, `Purchase`, etc.)
    * **Pixel ID** is correct
    * **User data** is populated (especially if you entered shipping details at checkout)
    * **Destination status** shows the event was forwarded to Meta
  </Step>

  <Step title="Confirm the event in Meta Events Manager">
    Switch to Meta Events Manager → Test Events. You should see the corresponding server event within 2-5 minutes.

    Look for:

    * The event name matches (e.g., `AddToCart` or `Purchase`)
    * The source shows **Server** (not just Browser)
    * The event details include user data parameters like `em` (hashed email), `ph` (hashed phone)

    If you see the event from both Browser and Server sources but only counted once, deduplication is working correctly.
  </Step>
</Steps>

## You'll Know It's Working When...

<Tip>
  Your end-to-end pipeline is validated when a single storefront action produces a matched event in both the Upstack Live Event Stream and Meta Events Manager. The Meta event should show **Server** as the source, include hashed user data parameters, and arrive within 5 minutes of the storefront action.
</Tip>

If any step fails, refer back to the relevant earlier step:

* Events not appearing in Upstack? See [Step 2: Verify Events Are Flowing](/get-started/verify-events)
* Events in Upstack but not Meta? See the troubleshooting section in [Step 3: Connect a Destination](/get-started/connect-a-destination)
