Connected System Objects

This article provides detailed design information about the Connected System design object and its configuration options. A connected system represents an external system that is integrated with Appian. You can upload a logo image to visually identify the system being called and can share connection details across multiple integrations.


Each connected system has the following properties.

Field Description
Name The name of the connected system. Use a name that will uniquely identify this connection to the external system.
Description Supplemental information about the connected system that is displayed when selecting the system in the integration designer and in the application contents grid.
System Logo An image document used to visually represent the external system or service being connected to. The logo is displayed in the integration designer and in the process modeler on integrations that connect to this system (using the Call Integration Smart Service). If no document is selected a default logo will be used instead.
Authentication The type of authentication to use for the integrations that use this connected system.
  • None: No specific authentication will be applied. You can provide custom authentication values in the integration's URL, parameters, or headers as required by the external system. Client certificate/mutual SSL authentication can be enabled by uploading client certificates in the Admin Console.
  • Basic: HTTP Basic authentication will be applied using the username and password provided.
Username The username to use for authentication. This value is encrypted and supports environment specific configuration.
Password The password to use for authentication. This value is masked, encrypted, and supports environment specific configuration.
Send credentials preemptively instead of waiting for a 401 authentication challenge Determines whether or not authentication credentials are sent only after a 401 Not Authorized response or, when selected, before the system has challenged.


The security rolemap of the connected system controls who can see or modify the connected system properties.

Connected systems can be used when calling an integration by any user regardless of their defined role in the security rolemap.

The following actions can be completed by each role:
