# Endpoint switcher

Our endpoint switcher works for every Cloud tab.

Endpoint switcher lets you provide your own endpoints and headers to query against your schema:

### Provide Headers

Each endpoint allows the creation of custom headers.

### CORS

You don't have to worry about CORS as all requests go through the GraphQL Editor proxy.
