# Rotating Your Merchant GUID

Follow these steps to rotate your Merchant GUID on SFCC. Production and Staging are rotated separately, and Staging has additional steps.

<Note>
  **Before you start**

  * Have your new Merchant GUID to hand.
  * Your Merchant ID does not change.
  * Questions? Contact your Global-e account manager.
</Note>

<Steps>
  <Step title="Open the Global-e site preferences">
    Open **Merchant Tools > Site Preferences > Custom Preferences > GLOBALE**.
  </Step>

  <Step title="Update the Merchant GUID">
    Update **Merchant GUID** (`geMerchantGuid`) with the new GUID.
  </Step>

  <Step title="Save">
    Save.
  </Step>

  <Step title="Repeat per site">
    Repeat for **every Global-e-operated site** on the instance — Site Preferences are set per site.
  </Step>
</Steps>

The following figure shows the **Merchant GUID** (`geMerchantGuid`) field under **Custom Site Preference Groups**:

Follow the same process as Production, then complete the additional steps below.

<Steps>
  <Step title="Check the GlobaleProducts job">
    Open **Administration → Operations → Jobs** and check whether the `GlobaleProducts` job exists and is enabled.
  </Step>

  <Step title="Follow the branch that matches what you found">
    Use the decision list below.
  </Step>
</Steps>

### If the job exists and is enabled

Which of the two locations holds the GUID depends on your cartridge version.

**Old versions of the Global-e SFCC cartridges** — open the job's **step configuration** and update the **Merchant GUID** parameter with the new GUID.

The following figure shows the `LoadRecentProductCountryS` step configuration, with the `geMerchantGuid` parameter:

</Frame>

**New versions of the Global-e SFCC cartridges** — check whether the SFCC service credential with ID `Globale-RecentProductCountryS` exists. If it does, open it and update the **Password** field with the new Merchant GUID.

The following figure shows the `Globale-RecentProductCountryS` row under **Service Credentials**:

</Frame>

The following figure shows the **Password** field on that credential:

</Frame>

<Tip>
  If the job is enabled, one of the two locations above will contain the current Production GUID. Update it accordingly. It is also recommended to verify whether the `GlobaleProducts` job is enabled in **SFCC Production**, as some older merchants have this job enabled in Production.
</Tip>

### If the job is missing or disabled

No changes to the `GlobaleProducts` job are required.
