# ACL Auth Method HTTP API

The `/acl/auth-method` endpoints [create](#create-an-auth-method),
[read](#read-an-auth-method), [update](#update-an-auth-method),
[list](#list-auth-methods) and [delete](#delete-an-auth-method)
ACL auth methods in Consul.

For more information on how to setup ACLs, please see
the [ACL Guide](https://learn.hashicorp.com/consul/advanced/day-1-operations/production-acls).

## Create an Auth Method

This endpoint creates a new ACL auth method.

| Method | Path                         | Produces                   |
| ------ | ---------------------------- | -------------------------- |
| `PUT`  | `/acl/auth-method`           | `application/json`         |

The table below shows this endpoint's support for
[blocking queries](/api/features/blocking.html),
[consistency modes](/api/features/consistency.html),
[agent caching](/api/features/caching.html), and
[required ACLs](/api/index.html#authentication).

| Blocking Queries | Consistency Modes | Agent Caching | ACL Required |
| ---------------- | ----------------- | ------------- | ------------ |
| `NO`             | `none`            | `none`        | `acl:write`  |

### Payload Fields

- `Name` `(string: <required>)` - Specifies a name for the ACL auth method. The
  name can contain alphanumeric characters, dashes `-`, and  underscores `_`.
  This field is immutable and must be unique.
   
- `Type` `(string: <required>)` - The type of auth method being configured.
  The only allowed value in Consul 1.5.0 is `"kubernetes"`. This field is
  immutable.

- `Description` `(string: "")` - Free form human readable description of the
  auth method.

- `Config` `(map[string]string: <required>)` - The raw configuration to use for
  the chosen auth method. Contents will vary depending upon the type chosen.
  For more information on configuring specific auth method types, see the [auth
  method documentation](/docs/acl/acl-auth-methods.html).
  
- `Namespace` `(string: "")` - **(Enterprise Only)** Specifies the namespace to 
  create the auth method within. If not provided in the JSON body, the value of
  the `ns` URL query parameter or in the `X-Consul-Namespace` header will be used. 
  If not provided at all, the namespace will be inherited from the request's ACL 
  token or will default to the `default` namespace. Added in Consul 1.7.0.

### Sample Payload

{
    "Name": "minikube",
    "Type": "kubernetes",

## Read an Auth Method

This endpoint reads an ACL auth method with the given name. If no
auth method exists with the given name, a 404 is returned instead of a
200 response.

| Method | Path                         | Produces                   |
| ------ | ---------------------------- | -------------------------- |
| `GET`  | `/acl/auth-method/:name`     | `application/json`         |

The table below shows this endpoint's support for
[blocking queries](/api/features/blocking.html),
[consistency modes](/api/features/consistency.html),
[agent caching](/api/features/caching.html), and
[required ACLs](/api/index.html#authentication).

| Blocking Queries | Consistency Modes | Agent Caching | ACL Required |
| ---------------- | ----------------- | ------------- | ------------ |

### Parameters

- `name` `(string: <required>)` - Specifies the name of the ACL auth method to
  read. This is required and is specified as part of the URL path.
  
- `ns` `(string: "")` - **(Enterprise Only)** Specifies the namespace to lookup
  the auth method within. This value can be specified as the `ns` URL query 
  parameter or in the `X-Consul-Namespace` header. If not provided by either,
  the namespace will be inherited from the request's ACL token or will default
  to the `default` namespace. Added in Consul 1.7.0.

### Sample Request

```sh
$ curl -X GET http://127.0.0.1:8500/v1/acl/auth-method/minikube
```

### Parameters

- `Name` `(string: <required>)` - Specifies the name of the auth method to
  update. This is required in the URL path but may also be specified in the
  JSON body. If specified in both places then they must match exactly.

- `Type` `(string: <required>)` - Specifies the type of the auth method being
  updated.  This field is immutable so if present in the body then it must
  match the existing value. If not present then the value will be filled in by
  Consul.

- `Description` `(string: "")` - Free form human readable description of the
  auth method.

- `Config` `(map[string]string: <required>)` - The raw configuration to use for
