# Consistency guarantees

> Consistency guarantees across the Voyado Elevate Admin and Storefront APIs.

Elevate provides different consistency guarantees depending on which API you use.

## Admin API v3 and v4

* **Read-after-write consistency:** When you perform a write operation (for example, an import), all subsequent read operations (such as exports) will immediately reflect the change.
* **Cross-version consistency:** Writes made through Admin API v3 are instantly visible when reading through Admin API v4, and vice versa.

<Warning>
  The `export/product-groups` endpoint in Admin API v3 does not follow the rules above. It is *eventually consistent*, just like the Storefront API, see below.
</Warning>

## Storefront API v3

* **Eventual consistency with Admin API:** Changes made through Admin API v3 or v4 will become visible in Storefront API v3, but not necessarily right away. In practice, updates are typically reflected within a few seconds or minutes.

Refer to the [Admin API v3](/elevate/docs/api/admin/v3/overview), [Admin API v4](/elevate/docs/api/admin/v4/overview), and [Storefront API v3](/elevate/docs/api/storefront/v3/overview) specifications for more information on available endpoints.
