What admin console section allows you to manage all connections to external systems?

The correct choice focuses on the management of connections to external systems, which is essential for ensuring that your Appian applications can interact effectively with other environments, such as databases and web services. The "Third-party Credentials" section is specifically designed for this purpose, allowing administrators to configure and maintain the necessary credentials required for authenticating connections to external systems securely.

This involves entering and managing information such as usernames, passwords, API keys, and other authentication details that are necessary for communication with those external systems. Therefore, this section is critical for establishing reliable integrations and facilitating data flow between Appian and other applications or services.

In contrast, while the "Data Sources" section also relates to external connections, it primarily focuses on the definition and configuration of data sources rather than managing the underlying authentication credentials. "Permissions" pertains to user access control and does not deal with external system connections. "Web API Authentication" specifically addresses the authentication methods for accessing Appian's own web APIs rather than connections to third-party systems. Thus, the management of third-party credentials is where the focus lies for external system connectivity.
