# Application entity

> Every request to the Integration API comes from your integrated webshop. Typically, an ecommerce site, a mobile app, or some other source of customer actions.

> For the complete documentation index, see [llms.txt](https://docs.talon.one/llms.txt).

The target of every request is a given Talon.One Application that contains your
campaigns.

You may have multiple Applications within one account, for example [staging and
production](/docs/product/applications/overview/#application-environments), or different
international markets.

:::note
You cannot share campaigns across different Applications, but you can [copy campaigns](/docs/product/campaigns/copy-campaigns.md)
to a different Application.
