# Deleting collections

Collections that are scheduled with BankTech may be deleted. This is usually done when ad hoc collections' mandates were amended, when collections are duplicated or when some other change caused them to become invalidated. Collections are identified by their 'collectionidentification' which is simply the unique reference used with BankTech. Collections can only be deleted in 1 way:

```
DELETE: /collections/bulk
```

This will delete the collections records.&#x20;
