# ACL Role HTTP API

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

The `/acl/role` endpoints [create](#create-a-role), [read](#read-a-role),
[update](#update-a-role), [list](#list-roles) and [delete](#delete-a-role) ACL roles in Consul.

For more information on how to setup ACLs, please check
the [ACL tutorial](https://learn.hashicorp.com/tutorials/consul/access-control-setup-production).

## Create a Role

This endpoint creates a new ACL role.

| Method | Path        | Produces           |
| ------ | ----------- | ------------------ |
| `PUT`  | `/acl/role` | `application/json` |

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

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

The corresponding CLI command is [`consul acl role create`](/commands/acl/role/create).

### Query Parameters

- `ns` `(string: "")` <EnterpriseAlert inline /> - Specifies the namespace of the role you create.
  You can also [specify the namespace through other methods](#methods-to-specify-namespace).

### JSON Request Body Schema

- `Name` `(string: <required>)` - Specifies a name for the ACL role. The name
  can contain alphanumeric characters, dashes `-`, and underscores `_`.
  This name must be unique.

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

- `Policies` `(array<PolicyLink>)` - The list of policies that should be
  applied to the role. A PolicyLink is an object with an "ID" and/or "Name"
  field to specify a policy. With the PolicyLink, roles can be linked to
  policies either by the policy name or by the policy ID. When policies are
  linked by name they will be internally resolved to the policy ID. With
  linking roles internally by IDs, Consul enables policy renaming without
  breaking tokens.

- `ServiceIdentities` `(array<ServiceIdentity>)` - The list of [service
  identities](/docs/security/acl#service-identities) that should be
  applied to the role. Added in Consul 1.5.0.

  - `ServiceName` `(string: <required>)` - The name of the service. The name
    must be no longer than 256 characters, must start and end with a lowercase
    alphanumeric character, and can only contain lowercase alphanumeric
    characters as well as `-` and `_`.

  - `Datacenters` `(array<string>)` - Specifies the datacenters the effective
    policy is valid within. When no datacenters are provided the effective
    policy is valid in all datacenters including those which do not yet exist
    but may in the future.

- `NodeIdentities` `(array<NodeIdentity>)` - The list of [node
  identities](/docs/security/acl#node-identities) that should be
  applied to the role. Added in Consul 1.8.1.

  - `NodeName` `(string: <required>)` - The name of the node. The name
    must be no longer than 256 characters, must start and end with a lowercase
    alphanumeric character, and can only contain lowercase alphanumeric
    characters as well as `-` and `_`.

  - `Datacenter` `(string: <required>)` - Specifies the nodes datacenter. This
    will result in effective policy only being valid in that datacenter.

- `Namespace` `(string: "")` <EnterpriseAlert inline /> - Specifies the namespace of the role you create.
  This field takes precedence over the `ns` query parameter,
  one of several [other methods to specify the namespace](#methods-to-specify-namespace).

  "Name": "example-role",
  "Description": "Showcases all input parameters",

## Methods to Specify Namespace <EnterpriseAlert inline />

ACL role endpoints
support several methods for specifying the namespace of the ACL role resources
with the following order of precedence:
1. `Namespace` field of the JSON request body -
  only applies to [create](#create-a-role) and [update](#update-a-role) endpoints
1. `ns` query parameter
1. `X-Consul-Namespace` request header
1. Namespace is inherited from the namespace of the request's ACL token (if any)
1. The `default` namespace
