API key

The API key is a secret key used for simplified authorization in the Yandex Cloud API. API keys are only used for service account authorization.

API keys do not expire. This means that this authentication method is simpler, but less secure. Use it if you can't automatically request an IAM token.

Users should store API keys on their own. Yandex Cloud only gives access to an API key while it is being created. If the key is lost or damaged, you cannot restore it. In this case, you can reissue the key or create a new one.

In the management console, the page with service account information shows, for each key, the date and time of its most recent use. This information allows you to track down unauthorized use of keys and to delete unused keys without the risk of disrupting Yandex Cloud services.

Using the tokenUsing the token

Enter the API key when accessing Yandex Cloud resources via the API. Provide the API key in the Authorization header in the following format:

Authorization: Api-Key <API_key>
