how to reactivate a survey with the API

I all,

I would like to know if there is any way to Deactivate a survey by using the API ( API )

I saw that there is an "activate_survey" function but I can't see the reveres one.

I need this ability in order to make the following scenario:
1. create a new survey
2. activate the survey
3. send the link for testing
4. make sure that all work as it should
5. DELETE all collected data
6. re-activate the survey
7. send to REAL respondents

Waiting for you advice

Does anyone has any ideas?
