title: "Channels"
Channels are a feature of Vendure which allows multiple sales channels to be represented in a single Vendure instance. A Channel allows you to:
Every Vendure server always has a default Channel, which contains all entities. Subsequent channels can then contain a subset of the above entities.

Use-cases of Channels include:
To specify which channel to use when making an API call, set the 'vendure-token' header to match the token of the desired Channel.
Channels can also be used to implement a multi-tenant or marketplace application. In such a setup, each merchant would have their own dedicated Channel and would be granted permissions on that Channel only.
For a detailed guide on how this would be set up, see our Multi-Tenant guide.
