How can you call a microflow from a button action in Mendix?

In Mendix, calling a microflow from a button action is accomplished by configuring the button's 'onClick' event. This event allows you to specify the microflow that should be executed when the button is clicked. By setting this up in the properties of the button, you can effectively trigger various business logic operations that are encapsulated in the microflow.

When you configure the 'onClick' event, you can select the desired microflow from a list, ensuring that it aligns with the functionality you want to achieve. This method seamlessly integrates user interaction with backend processes, allowing for a responsive application without the need for manual coding or additional logic checks.

The other options do not serve the purpose of directly associating a microflow with a button click. For example, entering the microflow name in a database doesn't create an actionable link between user interface elements and microflows. Writing server-side scripts is beyond the scope necessary for this interaction in Mendix's low-code environment, which is primarily designed to minimize coding. Linking to an external API does not pertain specifically to triggering a microflow from a button action within the Mendix application itself.
