📢 New Connector Builder Feature: Activity Designer (Public Preview)


The UiPath Connector Builder/activity designer allows you to preview the UI of an activity while you are in the process of building a custom connector from within Connector Builder. Each request parameter and response field configured for an activity will now have a display that reflects how that configuration impacts the final activity.

Input parameter placement can be modified on the activity by selecting the Main or Additional options while input parameters that require a value assigned during the automation’s setup can be marked with the Required field. This will place the field in the main section of the activity and, once the activity is used in a workflow, will display an error if no value is assigned. The order of the input parameters can also be updated by group (main and additional) allowing you to further customize the look and feel of an activity.

Response fields can also be Curated. Curated response fields will be broken out into their own variables, making for easy access throughout a workflow.

All of these customizations are immediately reflected through the Activity Designer resulting in a streamlined experience when building your own Connectors.

During this public preview phase, we are looking forward to learning about your experience with the Activity designer. Please share any issues you encounter while using the Activity designer. We are happy to learn where we can improve prior to moving this to GA.

Click into the Output tab to show the response fields (response fields only show after making a successful call using the Send Request button). From the Output tab, fields can be selected as Curated to be included as standalone variables in the Output section of the preview.

Within the activity preview, the name of the activity can be edited.
