# Apex for Snapchat

> Optimize Snapchat web campaigns toward Northbeam-attributed purchases with Northbeam Apex.

Snapchat Third-Party Web Optimization (3PO) lets Snap use Northbeam-attributed purchase outcomes, alongside its own signals, when training delivery models and making auction decisions. Paired with [Northbeam Apex](https://docs.northbeam.io/docs/northbeam-apex.md), your Snapchat web campaigns can optimize toward the same purchase outcomes you already use to judge media performance.

This guide walks through connecting Northbeam to Snapchat, creating a 3PO campaign, choosing a bid strategy, and reading results.

## Overview

**1. Configure Apex in Northbeam**

Choose your North Star metric, enable Snapchat as an Apex platform, and save.

**2. Connect Northbeam in Snap Events Manager**

Complete the Partner Integrations flow in Events Manager.

**3. Confirm account eligibility**

The third-party optimization option appears automatically in Ads Manager for eligible ad accounts.

**4. Create the campaign**

Choose the Sales objective, select **Third-party Measurement Partners** as the attribution method, then use auto-bid or target cost.

### What changes

* A new campaign-level attribution setting tells Snap to optimize toward third-party partner outcomes.
* Targeting, budgets, placements, and creative otherwise follow your normal web campaign workflow.
* Northbeam remains your measurement source of truth. Snap and Northbeam reporting won't match one for one.

> [!NOTE]
>
> Eligible accounts can use either **auto-bid** or **target cost** bidding. Account-level eligibility and the controls shown in Snap Ads Manager are always the definitive source.

## How 3PO compares to standard purchase optimization

| | Standard Snap purchase optimization | Northbeam 3PO |
| - | - | - |
| **Optimization signal** | Snap-attributed purchase signals | Snap signals plus Northbeam-attributed outcomes |
| **Campaign setup** | Snapchat attribution method | Third-party Measurement Partners attribution method |
| **Measurement lens** | Snap first-party reporting | Northbeam is your source of truth; Snap's modeled partner metrics support in-flight decisions |
| **Expected reporting** | Snap reporting follows its first-party methodology | Snap and Northbeam may report different totals because attribution methods and update timing differ |

### What 3PO doesn't change

* You don't need to change your Northbeam attribution settings to fit Snap.
* 3PO doesn't guarantee reporting parity between platforms.
* A completed Apex connection supports signal readiness, but doesn't by itself guarantee campaign eligibility.
* 3PO currently supports **web conversion campaigns only**, not app campaigns.

Results vary by advertiser and depend on signal readiness, bid calibration, conversion volume, and auction conditions.

## Before you start: readiness and eligibility

Snap Ads Manager unlocks third-party optimization automatically when your ad account meets the required checks. Review these before you begin so you can resolve common blockers early.

| Readiness check | What good looks like |
| - | - |
| **Web purchase campaign** | You'll use the Sales objective with a webview attachment. |
| **First-party purchase signal** | A standard Pixel Purchase goal-based bidding option is available in your ad account. |
| **Event passback** | Purchase events are mapped and sent through Snap Pixel or Conversions API (CAPI). |
| **Signal readiness** | Purchase signal readiness is **Okay** or **Good**, including healthy browser identifier coverage. |
| **Recent conversion volume** | Current guidance is an average of at least three partner-credited conversions per day over the prior 14 days. Thresholds can change. |
| **Measurement practice** | Northbeam is a meaningful source of truth for your budget and performance decisions. |

> [!NOTE]
>
> **Apex and 3PO are related but separate.** The Apex connection shares attribution context with Snap and supports signal-health checks. The 3PO campaign option controls how Snap bids and delivers. You may complete the Apex connection before the 3PO option appears, because eligibility also depends on signal quality and conversion volume.

## Step 1: Configure Apex in Northbeam

Complete this step in your Northbeam account. Keep your existing measurement approach intact; the goal is to share your Northbeam outcome definition with Snap.

**1. Open Settings**

Sign in to Northbeam and select **Settings** in the lower-left navigation.

**2. Open Apex**

Select **Apex** from the settings menu.

**3. Confirm your North Star metric**

Use the outcome definition you already rely on for performance decisions.

**4. Enable Snapchat**

Under **Apex Platforms**, select **Snapchat** and click **Save**.

Apex settings in Northbeam. Exact controls may vary.

> [!TIP]
>
> **Before moving to Snap:**
>
> * Verify the Snap ad account you intend to use is available to connect.
> * Note your North Star metric and attribution configuration for reference.
> * Confirm whoever completes the next step has access to your Snap Events Manager.

## Step 2: Connect Northbeam in Snap Events Manager

**1. Open Events Manager**

In Snap Ads Manager, open **Events Manager**.

**2. Open Partner Integrations**

Choose **Partner Integrations** from the left navigation.

**3. Select Northbeam**

Under **Measurement Partners**, expand the **Northbeam** tile and click **Connect**.

**4. Complete the guided flow**

Review the Northbeam account Snap discovered, click **Next** through the prompts, and click **Finish**.

![Snap Campaign Attribution](https://mintlify.s3.us-west-1.amazonaws.com/northbeam/images/snap-partner-integrations-1.png)

Northbeam appears under Measurement Partners in Partner Integrations.

![Snap Connect Northbeam](https://mintlify.s3.us-west-1.amazonaws.com/northbeam/images/snap-connect-northbeam.png)

Review the matched Northbeam account, then continue until the flow confirms completion.

Once finished, return to Events Manager and confirm Northbeam shows as connected.

> [!TIP]
>
> If the expected Northbeam account doesn't appear, review your Northbeam account-level permissions before retrying.

## Step 3: Create a 3PO campaign

Create the campaign through Snap's standard Sales workflow. The main change is the campaign attribution method.

**1. Choose Sales**

Start a new campaign and select the **Sales** objective.

**2. Choose the attribution method**

At the campaign level, under **Campaign Attribution**, select **Third-party Measurement Partners**.

**3. Confirm the Pixel**

Use the purchase Pixel associated with the connected ad account.

**4. Build the campaign**

Set targeting, placements, budget, creative, and webview attachment using your normal campaign practice.

![Snap Sales Objective 1](https://mintlify.s3.us-west-1.amazonaws.com/northbeam/images/snap-sales-objective-1.png)

Select the Sales objective.

![Snap Campaign Attribution 1](https://mintlify.s3.us-west-1.amazonaws.com/northbeam/images/snap-campaign-attribution-1.png)

Select Third-party Measurement Partners.

### What stays business as usual

* No targeting restrictions apply beyond your normal Snap policy and eligibility requirements.
* Budgets should support enough conversion volume for the model to learn.
* Single image, video, and collection ad formats follow your normal web campaign plan.
* The campaign must use a webview attachment. App optimization is outside the current 3PO scope.

## Step 4: Choose auto-bid or target cost

Eligible accounts can use either bid strategy. Choose the one that matches your operating model and the stability of your Northbeam-measured CPA.

| Strategy | Best for | Setup guidance |
| - | - | - |
| **Auto-bid** | New 3PO launches, or advertisers without a stable target cost | Gives the model room to explore and sustain delivery. Keep budget sufficient for learning and monitor Northbeam efficiency. |
| **Target cost** | Advertisers with a stable Northbeam CPA goal and enough purchase volume | Anchor the target to your Northbeam conversion economics. Don't automatically reuse the lower CPA or bid from a standard first-party campaign. |

> [!WARNING]
>
> **Your target cost may need to differ from your Snap Pixel CPA.** Northbeam often credits fewer purchases to Snap than Snap's first-party reporting does. A target cost based on your old first-party CPA can be too restrictive, limiting auction competitiveness, spend, and learning.

**Target cost starting approach**

* Use a representative Northbeam CPA as your baseline.
* Set a realistic starting target that reflects Northbeam-attributed purchase volume.
* Avoid frequent bid changes during the initial learning period.
* Work with your Snap sales representative for account-specific calibration.

## Reading performance in Northbeam and Snap

Use Northbeam for source-of-truth evaluation, and Snap's modeled partner metrics for in-platform pacing and bid decisions. Differences between the two are expected because their methodologies and update timing differ.

### Modeled partner metrics in Snap Ads Manager

| Metric | How it's determined |
| - | - |
| **Modeled Partner Purchases** | Estimated third-party-attributed purchases used in Snap reporting and optimization |
| **Modeled Partner Purchase Value** | Modeled partner purchases multiplied by the purchase value passed through Pixel or CAPI |
| **Modeled Partner Purchase ROAS** | Modeled partner purchase value divided by spend |
| **Cost Per Modeled Partner Purchase** | The in-platform cost metric most directly tied to target cost and other bid decisions |

### Recommended operating rhythm

| Question | Where to look |
| - | - |
| Is the campaign delivering and learning? | Snap Ads Manager delivery plus modeled partner purchase metrics |
| Is performance meeting my business goal? | Northbeam CPA, ROAS, and your North Star metric |
| Should I change bids or budgets? | Use both views, then make deliberate changes that preserve enough conversion volume for learning |

### Set expectations before launch

* 3PO aims for closer optimization alignment, not identical reporting.
* Partner data may update later than Snap's in-platform modeled metrics.
* Account setup, signal quality, bids, conversion volume, and auction conditions all affect results.
* An early reporting gap doesn't mean the integration is broken.

## Testing 3PO against standard optimization

Snap's self-serve Split Test tool doesn't currently support a direct comparison between standard first-party optimization and third-party partner optimization. If you want a controlled read, contact your Snap sales representative, who can engage Snap's Marketing Science team.

**How it works:**

1. You request a controlled first-party vs. 3PO comparison.
2. Snap Sales confirms eligibility and testing goals.
3. Snap Marketing Science designs a multi-cell split test.
4. You review Northbeam and Snap results together.

**Illustrative test structure**

| Cell | Optimization | Bid approach | Role |
| - | - | - | - |
| A | Standard first-party purchase | Your existing strategy | Control |
| B | Northbeam 3PO | Auto-bid | Treatment |
| C (optional) | Northbeam 3PO | Target cost calibrated to Northbeam economics | Additional treatment |

Snap Marketing Science finalizes the design. A few principles:

* The number of cells depends on expected conversion volume, budget, and statistical power.
* Cells should use comparable audiences, dates, creative, placements, and budgets unless the design specifies otherwise.
* Define Northbeam-measured CPA and ROAS (and any new-customer metric) as primary or secondary outcomes before launch.
* Running two campaigns side by side isn't a substitute for randomized measurement; audience and auction differences can bias the comparison.

> [!TIP]
>
> When requesting a test, share your ad account ID, expected spend, Northbeam attribution settings, primary KPI, candidate bid strategies, and proposed dates.

| **Purchase signal** | Pixel or CAPI purchase event is mapped and healthy |
| **Eligibility** | Third-party Measurement Partners can be selected |
| **Campaign** | Sales objective, webview attachment, correct Pixel, normal policy checks |
| **Bid strategy** | Auto-bid or a Northbeam-aligned target cost |
| **Measurement plan** | Northbeam KPIs and decision dates agreed before launch |

## Troubleshooting

> [accordion] My Northbeam account doesn't appear in Snap
>
> Confirm your Northbeam account permissions and that Snapchat is enabled under Apex Platforms in Northbeam.

> [accordion] The Third-party Measurement Partners option is locked or missing
>
> * Confirm the ad account and Pixel are the same ones connected through Northbeam Apex.
> * Review Purchase event passback and signal readiness in Events Manager.
> * Check your recent Northbeam-attributed purchase volume.
> * Ask your Snap sales representative to confirm eligibility or the current blocker.

> [accordion] Delivery is limited
>
> Check whether your target cost is anchored to an unrealistically low first-party CPA. Confirm your budget supports enough eligible conversion volume.

> [accordion] Snap and Northbeam numbers don't match
>
> Confirm your attribution settings and timing. Some discrepancy is expected and doesn't by itself indicate a problem.

> [accordion] I need a causal performance read
>
> Don't use Snap's self-serve Split Test tool for first-party vs. 3PO comparisons. Ask your Snap sales representative to involve Marketing Science.

## FAQ

> [accordion] Is the Apex integration the same as 3PO?
>
> No. Apex establishes data sharing and signal-readiness support. 3PO is the campaign optimization choice in Snap, and your ad account must still meet eligibility checks.

> [accordion] Do I need to change my Northbeam attribution model?
>
> No. Keep your existing Northbeam settings and source-of-truth methodology.

> [accordion] Which bid strategies are supported?
>
> Eligible accounts can currently use auto-bid or target cost.

> [accordion] Should my target cost equal my old Snap Pixel CPA?
>
> Usually not. Northbeam may credit fewer purchases to Snap, so a first-party CPA can be too restrictive. Use your Northbeam economics and account-specific guidance from Snap.

> [accordion] Will Snap and Northbeam report the same purchases and ROAS?
>
> No. The goal is closer optimization alignment. Methodology and timing differences mean reported totals may differ.

> [accordion] Can I compare first-party and 3PO in Snap's self-serve Split Test tool?
>
> Not currently. Contact your Snap sales representative to request a Marketing Science-led multi-cell test.

> [accordion] What if my account isn't eligible?
>
> Improve signal health, complete the Apex connection, confirm tracking hygiene, and build enough recent partner-attributed purchase volume. Your Snap sales representative can confirm the current blocker.

> [accordion] Are app campaigns supported?
>
> No. 3PO currently covers web campaigns with a webview attachment.
