### How do you add Help Scout Trigger to a Duaer digital organization?

Open the node panel on the Duaer canvas, search for Help Scout Trigger, and drop it onto the digital organization. Connect it after a trigger or a previous node. If auth is required, save the credential first and select it on the node.

Read the error text on that node’s output, then confirm the credential still works and required parameters are filled. For app nodes, also check permissions and quota on the provider side.
