There is no single operation in the API to delete an entire collection. Instead a collection comes into existence once a first document is added to it, and a collection disappears once the final document is deleted from it.

This means that you'll need to delete each document in the collection individually, preferably using batch delete operations. Once you've deleted the last document from the subcollection, the collection itself is also gone.
