??? warning "The router's [rule](../../routing/routers#rule) must catch requests for the URI path `/api`"
Using an "Host" rule is recommended, by catching all the incoming traffic on this host domain to the API.
However, you can also use "path prefix" rule or any combination or rules.
```bash tab="Host Rule"
# Matches http://traefik.domain.com, http://traefik.domain.com/api
# or http://traefik.domain.com/hello
rule = "Host(`traefik.domain.com`)"

### Dashboard Router Rule
As underlined in the [documentation for the `api.dashboard` option](./api.md#dashboard),
the [router rule](../routing/routers/index.md#rule) defined for Traefik must match
the path prefixes `/api` and `/dashboard`.
We recommend to use a "Host Based rule" as ```Host(`traefik.domain.com`)``` to match everything on the host domain,
or to make sure that the defined rule captures both prefixes:
```bash tab="Host Rule"
# Matches http://traefik.domain.com/api or http://traefik.domain.com/dashboard
rule = "Host(`traefik.domain.com`)"
```
```bash tab="Path Prefix Rule"
# Matches http://traefik.domain.com/api , http://domain.com/api or http://traefik.domain.com/dashboard
# but does not match http://traefik.domain.com/hello
rule = "PathPrefix(`/api`) || PathPrefix(`/dashboard`)"
```
```bash tab="Combination of Rules"
# Matches http://traefik.domain.com/api or http://traefik.domain.com/dashboard
# but does not match http://traefik.domain.com/hello
rule = "Host(`traefik.domain.com`) && (PathPrefix(`/api`) || PathPrefix(`/dashboard`))"
```
