# ACL Auth Method HTTP API

-> **1.5.0+:** The auth method APIs are available in Consul versions 1.5.0 and newer.

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

```json
{
  "Name": "minikube",
  "Type": "kubernetes",
  "Description": "dev minikube cluster",

## 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           |
| ------ | ------------------------ | ------------------ |

The table below shows this endpoint's support for
[blocking queries](/api/features/blocking.html),
[consistency modes](/api/features/consistency.html),

| Blocking Queries | Consistency Modes | Agent Caching | ACL Required |
| ---------------- | ----------------- | ------------- | ------------ |
| `YES`            | `all`             | `none`        | `acl:read`   |

### 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.

## Update an Auth Method

This endpoint updates an existing ACL auth method.

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

  auth method.
