Thanks @BramKn , you’d given me hope by sharing your HTML response using “Respond to Webhook” node with Text output that responding to XML is possible. @jan please consider updating sample xml workflow to use Respond to Webhook with Response Header, Content-Type : application/xml, as the sample didn’t return native xml but xml wrapped within json array.
For information, the output is different between “When Last Node Finishes” and “Using Respond to Webhook node” with the same end node.
