One of our customer has a Google Enterprise Account (G Suite). We have developed an application on Google Site that use a Spread Sheet. We have created a project in the google developer console to access the Spread Sheet form the Api and created a Service Account for this project. Everything was created with our account (provided by the customer). At some point our account can be deleted or deactivated by the customer.
What happens then? Will the project be deleted/deactivated? Will the data in the drive be lost?
Thanks
If an account on Google developer console is deleted then yes all the projects and clients associated with that account will stop working.
I am not sure i understand where this sheet is located. If the sheet is on the service accounts google drive account then yes you will loose that as well.
Once a user is deleted or deactivated anything that the account contained is gone.
