Environment for debugging apps that access the Yandex Direct API.
The sandbox simulates the Yandex Direct API, but is completely isolated from actual data. It is a playground where you can invoke API methods, get responses, and observe changes to test campaigns and ads. Those operations that are available in the API only when there are sufficient funds are always available in the Sandbox, without having to actually credit funds to an account.
Requests sent to the Sandbox do not modify data in Yandex Direct. Ads that are created are not actually displayed anywhere, and funds that are deducted and credited do not affect real campaigns. However, the entire set of possible campaign states is simulated, from under review to stopping displays due to insufficient funds. Although statistical reports contain simulated data, their structure is the same as a real report. This makes the Sandbox a fully-functional environment for debugging applications.
Sandbox data is stored for a month from the last time it was accessed, and then it is deleted.
