## Specification

This section provides details about the fields you can configure in the `http-route` configuration entry.

### `Kind`

Specifies the type of configuration entry to implement. For HTTP routes, this must be `http-route`.

#### Values

- Default: none
- This field is required.
- Data type: string value that must be set to `"http-route"`.

### `Name`

Specifies a name for the configuration entry. The name is metadata that you can
use to reference the configuration entry when performing Consul operations,
such as applying a configuration entry to a specific cluster.

#### Values

- Default: Defaults to the name of the node after writing the entry to the Consul server.
- This field is required.
- Data type: string

### `Namespace` <EnterpriseAlert inline />

Specifies the Enterprise [namespace](/consul/docs/enterprise/namespaces) to apply to the configuration entry.

#### Values

- Default: `"default"` in Enterprise
- Data type: string

### `Partition` <EnterpriseAlert inline />

Specifies the Enterprise [admin partition](/consul/docs/enterprise/admin-partitions) to apply to the configuration entry.

#### Values

- Default: `"default"` in Enterprise
- Data type: string

### `Meta`

Specifies an arbitrary set of key-value pairs to associate with the route.

#### Values

- Default: none
- Data type: map containing one or more keys and string values.

  - `Partition` <EnterpriseAlert inline />
  - `SectionName`

### `Parents[].Kind`

Specifies the type of resource to bind to. This field is required and must be
set to `"api-gateway"`

#### Values

- Default: none
- This field is required.
- Data type: string value set to `"api-gateway"`

### `Parents[].Name`

Specifies the name of the api-gateway to bind to.

#### Values

#### Values

- Default: `"default"` in Enterprise
- Data type: string

### `Parents[].Partition` <EnterpriseAlert inline />

Specifies the Enterprise [admin partition](/consul/docs/enterprise/admin-partitions) to apply to the configuration entry.

#### Values

- Default: `"default"` in Enterprise
- Data type: string

### `Parents[].SectionName`

Specifies the name of the listener to bind to on the `api-gateway`. If left
empty, this route binds to _all listeners_ on the parent gateway.

#### Values

- Default: ""
- Data type: string

### `Rules[]`

Specifies the list of HTTP-based routing rules that this route uses to construct a route table.

#### Values

- Default:
- Data type: List of maps. Each member of the list contains the following fields:
  - `Filters`
  - `Matches`
  - `Services`

### `Rules[].Filters[]`

Specifies the list of HTTP-based filters used to modify a request prior to routing it to the upstream service.

#### Values

- Default: none
- Data type: Map that contains the following fields:
  - `Headers`
  - `UrlRewrite`
  - `RetryFilter`
  - `TimeoutFilter`

### `Rules[].Filters[].Headers[]`

Defines operations to perform on matching request headers when an incoming request matches the `Rules.Matches` configuration.

#### Values

This field contains the following configuration objects:

| Parameter | Description                                                                                                                                                                                                                                                                                                                                                                                                                                  | Type            |
| --------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------- |
| `set`     | Configure this field to rewrite the HTTP request header. It specifies the name of an HTTP header to overwrite and the new value to set. Any existing values associated with the header name are overwritten. You can specify the following configurations: <ul><li>`name`: Required string that specifies the name of the HTTP header to set.</li><li>`value`: Required string that specifies the value of the HTTP header to set.</li></ul> | List of maps    |

### `Rules[].Matches[]`

Specifies the matching criteria used in the routing table. When an incoming
request matches the given HTTPMatch configuration, traffic routes to
services specified in the [`Rules.Services`](#rules-services) field.

  - `Headers`
  - `Method`
  - `Path`
  - `Query`

### `Rules[].Matches[].Headers[]`

You can create multiple `Header[]` lists to create a range of matching criteria. When at least one list of matching rules are satisfied, the route forwards the request to the appropriate service defined in the [`Rules.Services`](#rules-services) configuration.

#### Values

- Default: none
- Data type: List containing maps with the following fields:
  - `Match`
  - `Name`
  - `Value`

### `Rules.Matches.Headers.Match`

Specifies type of match for headers: `"exact"`, `"prefix"`, or `"regex"`.

#### Values

- Default: none
- Data type: string

### `Rules.Matches.Headers.Name`

Specifies the name of the header to match.

#### Values

- Default: none
- Data type: string

### `Rules[].Matches.Headers.Value`

Specifies the value of the header to match.

#### Values

- Default: none
- Data type: string

### `Rules[].Matches[].Method`

Specifies a list of strings that define matches based on HTTP request method.

#### Values

Specify one of the following string values:

- `HEAD`
- `POST`
- `PUT`
- `PATCH`
- `GET`
- `DELETE`
- `OPTIONS`
- `TRACE`
- `CONNECT`

### `Rules[].Matches[].Path`

Specifies the HTTP method to match.

#### Values

- Default: none
- Data type: map containing the following fields:
  - `Match`
  - `Value`

### `Rules[].Matches[].Path.Match`

Specifies type of match for the path: `"exact"`, `"prefix"`, or `"regex"`.

If set to `prefix`, Consul uses simple string matching to identify incoming request prefixes. For example, if the route is configured to match incoming requests to services prefixed with `/dev`, then the gateway would match requests to `/dev-` and `/deviate` and route to the upstream.

This deviates from the
[Kubernetes Gateway API specification](https://gateway-api.sigs.k8s.io/references/spec/#gateway.networking.k8s.io%2fv1beta1.PathMatchType), which matches on full path elements. In the previous example, _only_ requests to `/dev` or `/dev/` would match.

weights in the service list. For non-zero values, there may be some deviation
from the exact proportion depending on the precision an implementation
supports. Weight is not a percentage and the sum of weights does not need to
equal 100.
