What type of input parameter is required for the delete microflow of a delete method?

In Mendix, when working with the delete microflow of a delete method, the requisite input parameter is the unique ID of the object to be deleted. This ID serves as an identifier for the specific object within the domain model, allowing the microflow to locate and remove it from the database correctly.

Using the unique ID is crucial because it ensures that the exact object intended for deletion is targeted, particularly in situations where multiple objects may exist in the application with similar attributes. By specifying the unique ID, developers can explicitly refer to one distinct object without ambiguity.

The other options do not provide the necessary specificity required for the delete operation. A unique name, for example, could lead to errors if multiple objects share the same name. A collection of objects would complicate the delete process, as it’s not feasible to delete multiple objects at once using a single delete microflow unless specifically designed to handle collections. A user-defined attribute name lacks the necessary context for identifying a specific object to delete, as it does not inherently define which object is being referred to in the database.
