# MNTN Setup

> Connect MNTN with an API key and turn on Clicks + Deterministic Views so Northbeam can credit your MNTN impressions.

When you're done, Northbeam shows your MNTN spend and uses MNTN impressions to give view credit under **Clicks + Deterministic Views (C+DV)**.

<Info>
  **Before you start**, make sure you have:

  * A **MNTN account** login with access to **My Account → API** and **My Account → Integrations**
  * Access to [Connections](https://dashboard.northbeam.io/settings/connections) and **Model Settings** in Northbeam
  * The same **order ID** format sent to MNTN and Northbeam (for example, Shopify order numbers)

    **Turn on the integration in MNTN**

    After you connect your API key in Northbeam, finish setup from inside MNTN:

    1. Sign in to your **MNTN account**.
    2. Click your account name in the top-right corner and select **My Account**.
    3. In the left menu, click **Integrations**.
    4. Under **Analytics Integrations**, find **Northbeam** and click **Connect**.

    You'll see a confirmation message, and data starts syncing automatically within 24–48 hours. For full instructions, see MNTN's [Integration Guide](https://help.mountain.com/en/articles/11644276-integrate-northbeam).

    <Warning>
      **Remove legacy tags.** If you set up legacy MNTN impression tags for Northbeam in the past, remove them after you turn on the new C+DV integration. Keeping them can cause duplicate or conflicting impression data.
    </Warning>

    **If you skip this step:** Northbeam doesn't get your MNTN spend or the impressions it needs for C+DV matching.

    <Note>
      **How MNTN data processes**

      * After first setup, data can take up to **3 days** to fully backfill.
      * Once live, **C+DV data processes 3× per day**.
      * **Last retrieved** is when Northbeam last received data from MNTN.
      * **Last processed** is when that data was last processed and visible in the dashboard.
    </Note>

    **If you skip this step:** MNTN impression data doesn't show up in Northbeam.
  </Step>

  <Step title="Confirm tracking">
    <span id="step-5-verify-order-id-alignment" style={{ display: "block", scrollMarginTop: "7rem" }} />

    **Check that order IDs match.** MNTN uses order IDs for deterministic matching.

    1. In Northbeam, go to **Orders → Order ID** and note your order ID format (for example, Shopify order numbers).
    2. In MNTN, make sure the **same order ID format** is being passed to Northbeam.
    3. If they don't match, update your MNTN setup or [contact Support](https://www.northbeam.io/submit-a-support-ticket) to adjust the configuration.

    Mismatched order IDs block deterministic matching, so C+DV data won't show up.

    Then run the full check:

    * **Connection syncing:** follow [Checking platform connections](/docs/checking-api-connections) to confirm the account shows as connected and data is arriving.

    If a check fails, see [Troubleshooting Northbeam data](/docs/troubleshooting-tracking-issues).
  </Step>
</Steps>
