As a user with the Experience designer role, you can create validation for your form fields so users enter more relevant data. You add these validation rules to the model. It means you can enforce business rules and provide messages to your users to make forms easier to complete and ensure higher quality data.
You can set the conditions when you want the message to appear. For example, if a date should be in the past and not in the future, you can select and if/then branch and set the condition for the property value to not be after today.
A form needs to meet all active validation rules before Applaud triggers any workflows you have for the model.
It is important that when you design your messages that they are helpful to your users. A good resource to learn more about message design is Microsoft's guide, Messages (Design basics).
Raise error message
Message colors adhere to your configured brand within Applaud. Therefore, colors might differ from those shown here.
You can add a validation to reject the property value entered and show an error message to the user. Here we have added the condition that the Published date value is after today and want the user to update it before we save it.

Send warning message
A warning message will let the user save the changes but shows a warning message.

Send info message
You can give additional information when a user uses the form.

Send success message
You can confirm that the user has entered a valid value by showing a success message.
