# ACL Auth Methods HTTP API

The `/acl/auth-methods` and `/acl/auth-method` endpoints are used to manage ACL Auth Methods.

## Create Auth Method

This endpoint creates an ACL Auth Method. The request is always forwarded to the
authoritative region.

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

The table below shows this endpoint's support for
[blocking queries](/api-docs#blocking-queries) and
[required ACLs](/api-docs#acls).

| Blocking Queries | ACL Required |
| ---------------- | ------------ |
| `NO`             | `management` |

### Parameters

- `Name` `(string: <required>)` - Names is the identifier of the ACL Auth
  Method.  The name can contain alphanumeric characters, dashes, and underscores.
  This name must be unique and must not exceed 128 characters.

- `Type` `(string: <required>)` - ACL Auth Role SSO identifier. Currently, the
  only supported Type is "OIDC."

- `TokenLocality` `(string: <required>)` - Defines whether the ACL Auth Method
  creates a local or global token when performing SSO login. This field must be
  set to either "local" or "global"

- `MaxTokenTTL` `(duration: <required>)` - Defines the maximum life of a token created
  by this method. When set, it will initialize the `ExpirationTime` field on all
  tokens to a value of `Token.CreateTime + AuthMethod.MaxTokenTTL`. This field is
  not persisted beyond its initial use. Can be specified in the form of `"60s"` or
  `"5m"` (i.e., 60 seconds or 5 minutes, respectively).

- `Default` `(bool: false)` - Defines whether this ACL Auth Method is to be
  set as default when running `nomad login` command.

- `Config` `(ACLAuthMethodConfig: <required>)` - The raw configuration to use for
  the auth method. This parameter is part of the auth method configuration, not
  specific to Nomad.

  - `OIDCDiscoveryURL` `(string: <required>)` - The OIDC Discovery URL, without
    any .well-known component (base path).

  - `OIDCClientID` `(string: <required>)` - The OAuth Client ID configured with
    your OIDC provider.

  - `OIDCClientSecret` `(string: <required>)` - The OAuth Client Secret
    configured with your OIDC provider.

  - `BoundAudiences` `(array<string>)` - List of aud claims that are valid for
    login; any match is sufficient.

  - `AllowedRedirectURIs` `(array<string>)` - A list of allowed values for
    redirect_uri. Must be non-empty.

  - `DiscoveryCaPem` `(array<string>)` - PEM encoded CA certs for use by the TLS
    client used to talk with the OIDC Discovery URL. If not set, system
    certificates are used.

  - `SigningAlgs` `(array<string>)` - A list of supported signing algorithms.
    Defaults to `RS256`.

  - `ClaimMappings` `(map[string]string)` - Mappings of claims (key) that will
    be copied to a metadata field (value). Use this if the claim you are capturing
    is singular (such as an attribute).

    When mapped, the values in each list can be any of a number, string, or
    boolean and will all be stringified when returned.

  - `ListClaimMappings` `(map[string]string)` - Mappings of claims (key) will be
    copied to a metadata field (value). Use this if the claim you are capturing is
    list-like (such as groups).
