# Maintain Your Managed External Client App

When you create a contact center, Salesforce automatically generates a managed external client app (ECA) to handle your SAML single sign-on (SSO) authentication. Because Salesforce manages this external client app as part of your contact center provisioning, you can’t access or edit it from the External Client App Manager in Setup. Instead, manage all settings and policies for this app from your contact center settings.

### Required Editions

When you refresh a sandbox and recreate your contact center, manage the profiles or permission sets from the **Contact Center Details** page. This is because only packaged external client apps are copied to the sandbox during a sandbox refresh.

Note For Voice that’s manually integrated with your Amazon Connect instance by importing the contact center definition file, you can edit the local external client app only from the External Client Apps Manager. See [Create Local External Client App for Manually Integrated Contact Centers](https://help.salesforce.com/s/articleView?id=service.voice_create_connected_app.htm&type=5&language=en_US).

To view or edit the settings for your managed external client app:

1. From Setup, in the Quick Find box, enter `Voice`, and then select **Voice Settings**.
2. Click the name of your contact center to open the Contact Center Details page.

From the Contact Center Details page, manage these external client app configurations:

- SAML Policies: Update your authentication settings, such as the Entity URL, ACS URL, Issuer, and identity provider certificates.
- Custom Attributes: Edit the values for specific custom attributes, such as the RoleSessionName attribute used in the custom username format of contact center users.
- App Policies: Assign or remove user profiles and permission sets to control which users can log in to the contact center and your telephony provider.

Note

If you use Salesforce Contact Center with Amazon Connect (SCC-AC) and rely on connected apps, contact Salesforce Support to enable the **Allow creation of connected apps** org setting to create new connected apps. Existing SCC-AC connected apps continue to work and can be installed in new orgs via the SCC-AC package installation. For more information, see [this page](https://help.salesforce.com/s/articleView?id=005228017&type=1&language=en_US).
