Service Success/Error Notification
ThingWorx allows you to set custom success and error messages when a service successfully executes or fails to execute. These show up as pop-ups.
To do this in the Mashup Builder, follow these steps:
1. Select your service and click the Configure icon (between the Service Data and Service Properties panes).
2. At the bottom of the Configuration/Bindings window, in the Success and Error notification, click to activate.
3. Type a custom message.
