# ACL HTTP API

-> **The legacy ACL system was deprecated in Consul 1.4.0 and removed in Consul 1.11.0.** It's _strongly_
recommended you do not build anything using the legacy system and use
the new ACL [Token](/api/acl/tokens) and [Policy](/api/acl/policies) APIs instead.

The legacy `/acl` endpoints to create, update, destroy, and query legacy ACL tokens in Consul.

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

## Create ACL Token

This endpoint makes a new ACL token.

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

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

| Blocking Queries | Consistency Modes | Agent Caching | ACL Required |
| ---------------- | ----------------- | ------------- | ------------ |
| `NO`             | `none`            | `none`        | `management` |

### Parameters

- `ID` `(string: "")` - Specifies the ID of the ACL. If not provided, a UUID is
  generated.

- `Name` `(string: "")` - Specifies a human-friendly name for the ACL token.

- `Type` `(string: "client")` - Specifies the type of ACL token. Valid values
  are: `client` and `management`.

- `Rules` `(string: "")` - Specifies rules for this ACL token. The format of the
  `Rules` property is detailed in the [ACL Rule documentation](/docs/security/acl/acl-rules).

### Sample Payload

```json
{
  "Name": "my-app-token",
  "Type": "client",
  "Rules": ""
}
```

### Sample Request

$ curl \
    --request PUT \
    --data @payload.json \
    http://127.0.0.1:8500/v1/acl/create
```

### Sample Response

```json
{
  "ID": "adf4238a-882b-9ddc-4a9d-5b6758e4159e"
}
```

## Update ACL Token

This endpoint is used to modify the policy for a given ACL token. Instead of
generating a new token ID, the `ID` field must be provided.

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

[blocking queries](/api/features/blocking),
[consistency modes](/api/features/consistency),
[agent caching](/api/features/caching), and
[required ACLs](/api#authentication).

| Blocking Queries | Consistency Modes | Agent Caching | ACL Required |
| ---------------- | ----------------- | ------------- | ------------ |
| `NO`             | `none`            | `none`        | `management` |

### Parameters

The parameters are the same as the _create_ endpoint, except the `ID` field is
required.

### Sample Payload

```json
{
  "ID": "adf4238a-882b-9ddc-4a9d-5b6758e4159e",
  "Name": "my-app-token-updated",
  "Type": "client",
  "Rules": "# New Rules"
}
```

### Sample Request

```shell-session
$ curl \
    --request PUT \
    --data @payload.json \
    http://127.0.0.1:8500/v1/acl/update
```

### Sample Response

```json
{
  "ID": "adf4238a-882b-9ddc-4a9d-5b6758e4159e"
}
```

## Delete ACL Token

This endpoint deletes an ACL token with the given ID.

| Method | Path                 | Produces           |
| ------ | -------------------- | ------------------ |
| `PUT`  | `/acl/destroy/:uuid` | `application/json` |

Even though the return type is application/json, the value is either true or
false, indicating whether the delete succeeded.

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

| Blocking Queries | Consistency Modes | Agent Caching | ACL Required |
| ---------------- | ----------------- | ------------- | ------------ |
| `NO`             | `none`            | `none`        | `management` |

### Parameters

- `uuid` `(string: <required>)` - Specifies the UUID of the ACL token to
  destroy. This is required and is specified as part of the URL path.

### Sample Request

```shell-session
$ curl \
    --request PUT \
    http://127.0.0.1:8500/v1/acl/destroy/8f246b77-f3e1-ff88-5b48-8ec93abf3e05
```

### Sample Response

```json
true
```

## Read ACL Token

This endpoint reads an ACL token with the given ID.

| Method | Path              | Produces           |
| ------ | ----------------- | ------------------ |
| `GET`  | `/acl/info/:uuid` | `application/json` |

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

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

Note: No ACL is required because the ACL is specified in the URL path.

### Parameters

- `uuid` `(string: <required>)` - Specifies the UUID of the ACL token to
  read. This is required and is specified as part of the URL path.

### Sample Request

```shell-session
$ curl \

## Clone ACL Token

This endpoint clones an ACL and returns a new token `ID`. This allows a token to
serve as a template for others, making it simple to generate new tokens without
complex rule management.
