When you say:-
I can only call the Delete API from the outside once a day and only for a period of a maximum of 7 days.
Can this be changed or is there another option to delete data areas?
Solution
Currently, it's not possible to delete the data for more than 7 days through the API by the range request and it's mentioned in the documentation:-
The range of a delete request cannot be greater than 7 days.
