# Update Marketing Cloud Engagement API User

Change the Marketing Cloud Engagement API User for the Marketing Cloud Connect for Marketing Cloud Engagement integration.

![Warning](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_cross-cloud_products-264-0-0-production-enus/bd617332-480f-48e8-b283-3477883c1320/images/icon_warning.png)

Warning When you update Marketing Cloud Engagement API user credentials, email send processing stops and can result in failed triggered or scheduled sends. Before updating the API user, pause all email sends and deactivate triggered sends.

1. Log out of all active Engagement sessions in your browser.
2. In Sales or Service Cloud, go to the Marketing Cloud tab.
3. Click **Configure Marketing Cloud Connector**.
    
    If your integration token expired, click **Connect to Marketing Cloud** and enter the API user credentials to log in to Engagement and refresh the token.
4. Click **Change API User**.
    
    ![Important](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_cross-cloud_products-264-0-0-production-enus/bd617332-480f-48e8-b283-3477883c1320/images/icon_important.png)
    
    Important If you’re logged in to an active Engagement session in another tab, the system connects to that user. Log out of that session if it isn’t the Marketing Cloud Engagement API user.
5. Enter the updated Marketing Cloud Engagement API user credentials.
6. Click **Update API User**.

All Marketing Cloud Connect users are asked to reauthenticate the next time they log in to Marketing Cloud Connect.
