Using custom actions

If you’re using a custom action, you will see, in read-only, the URL Configuration and Authentication parameters defined in the action configuration screen (see this page).


You cannot pass a collection in custom action parameters. If the custom action expects collections, it will not work. Also note that the parameters have an expected format (example: string, decimal, etc.). You must be careful to respect these expected formats.

In the Action parameters section, you’ll see the message parameters defined as “Variable”. For these parameters, you can define where to get this information (example: events, data sources), pass values manually or use the advanced expression editor for advanced use cases. Advanced uses cases can be data manipulation and other function usage. See this page
