# General

The intratool API is tenant-based. Each organization uses its own intratool instance, identified by the `{tenant}` subdomain.

## Base URL and Tenant

Send every API request to the base URL of the affected intratool instance:

`https://{tenant}.intratool.de`

**Tenant placeholder**

Replace `{tenant}` with the organization's subdomain. For an instance available at `my-company.intratool.de`, the API base URL is `https://my-company.intratool.de`.

## Request Headers

Send the `Accept: application/json` header with every API request so error and validation responses use JSON instead of HTML.
