To disassociate a particular group of API keys from an API, you can delete a key collection together with all its components, including ACL settings and a user quota configuration. This operation is permanent – you cannot restore deleted keys and collections.
If you do not want to delete an entire collection and remove all keys permanently, consider revoking keys instead. See Revoke keys.
You can also complete this task by using the API Keys and Traffic Management API. Run the Delete a key collection operation.
In API Keys and Traffic Management, from the Key collections list on the left, select the collection that you want to delete.
In the top-right corner of the collection panel, click (...) .
In the menu, click Delete key collection.
In the confirmation window, click Yes.
