Before you begin
These instructions assume you are already editing a message flow in the Edit Message Flow page, as explained in Creating, Editing, and Viewing Message Flows.
The instructions also assume you have created a route node, as explained in Adding Route Nodes to Message Flows.
To add a Route Node Handler
Since an error handler is another pipeline, it is configured like any other pipeline. For example, the Publish action may be used to send error notifications to other services, the Assign action may be used to modify the context variables, and so on. To learn more about the type of action you want to add, see the appropriate procedure in Adding and Editing Actions in Message Flows. There is no restriction on what actions may be chained together.
Three commonly-used error actions are Raise Error, Reply, and Resume.
After you finish
On the Edit Message Flow page, continue to construct the message flow, as described in Creating, Editing, and Viewing Message Flows.
