Custom actions enable you to configure connection of a third-party system to send messages or API calls. An action can be configured with any service from any provider that can be called through a REST API with a JSON-formatted payload.
The configuration pane of the Custom action activity shows the URL configuration parameters and the authentication parameters that are configured for the custom action. You cannot set up the static part of the URL in the journey, but in the global configuration of the custom action. Learn more.
If the URL includes a dynamic path, specify the path in the Path field.

Advanced uses cases can be data manipulation and other function usage. Refer to this page.
