# Delete a Triggered Send Definition

To delete a triggered send definition, use the sample code below as a model for creating your own API request. Marketing Cloud Engagement changes the external key and name of a triggered send definition after it is deleted. This change allows you to reuse deleted names and external keys for new triggered send definitions.

**note:** API requests that refer to a deleted triggered send definition always result in failure.
