# ACL Tokens HTTP API

The `/acl/bootstrap`, `/acl/tokens`, and `/acl/token/` endpoints are used to manage ACL tokens.
For more details about ACLs, please see the [ACL Guide](/guides/security/acl).

## Bootstrap Token

This endpoint is used to bootstrap the ACL system and provide the initial management token.
This request is always forwarded to the authoritative region. It can only be invoked once
until a [bootstrap reset](/guides/security/acl#reseting-acl-bootstrap) is performed.

| Method | Path             | Produces           |
| ------ | ---------------- | ------------------ |
| `POST` | `/acl/bootstrap` | `application/json` |

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

| Blocking Queries | ACL Required |
| ---------------- | ------------ |
| `NO`             | `none`       |

### Sample Request

```shell
$ curl \
    --request POST \
    https://localhost:4646/v1/acl/bootstrap
```

### Sample Response

```json
{
  "AccessorID": "b780e702-98ce-521f-2e5f-c6b87de05b24",
  "SecretID": "3f4a0fcd-7c42-773c-25db-2d31ba0c05fe",
  "Name": "Bootstrap Token",
  "Type": "management",
  "Policies": null,
  "Global": true,
  "CreateTime": "2017-08-23T22:47:14.695408057Z",
  "CreateIndex": 7,
  "ModifyIndex": 7
}
```

## List Tokens

This endpoint lists all ACL tokens. This lists the local tokens and the global
tokens which have been replicated to the region, and may lag behind the authoritative region.

| Method | Path          | Produces           |
| ------ | ------------- | ------------------ |
| `GET`  | `/acl/tokens` | `application/json` |

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

| Blocking Queries | Consistency Modes | ACL Required |
| ---------------- | ----------------- | ------------ |
| `YES`            | `all`             | `management` |

### Parameters

- `prefix` `(string: "")` - Specifies a string to filter ACL tokens based on an
  accessor ID prefix. Because the value is decoded to bytes, the prefix must
  have an even number of hexadecimal characters (0-9a-f). This is specified as
  a query string parameter.

### Sample Request

```shell
$ curl \
    https://localhost:4646/v1/acl/tokens
```

```shell
$ curl \
    --request POST \
    https://localhost:4646/v1/acl/tokens?prefix=3da2ed52
```

### Sample Response

```json
[
  {
    "AccessorID": "b780e702-98ce-521f-2e5f-c6b87de05b24",
    "Name": "Bootstrap Token",
    "Type": "management",
    "Policies": null,
    "Global": true,
    "CreateTime": "2017-08-23T22:47:14.695408057Z",
    "CreateIndex": 7,
    "ModifyIndex": 7
  }
]
```

## Create Token

This endpoint creates an ACL Token. If the token is a global token, the request
is forwarded to the authoritative region.

| Method | Path         | Produces           |
| ------ | ------------ | ------------------ |
| `POST` | `/acl/token` | `application/json` |

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

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

### Parameters

- `Name` `(string: <optional>)` - Specifies the human readable name of the token.

- `Type` `(string: <required>)` - Specifies the type of token. Must be either `client` or `management`.

- `Policies` `(array<string>: <required>)` - Must be null or blank for `management` type tokens, otherwise must specify at least one policy for `client` type tokens.

- `Global` `(bool: <optional>)` - If true, indicates this token should be replicated globally to all regions. Otherwise, this token is created local to the target region.

### Sample Payload

```json
{
  "Name": "Readonly token",
  "Type": "client",
  "Policies": ["readonly"],
  "Global": false
}
```

## Update Token

This endpoint updates an existing ACL Token. If the token is a global token, the request
is forwarded to the authoritative region. Note that a token cannot be switched from global
to local or visa versa.

[blocking queries](/api#blocking-queries) and
[required ACLs](/api#acls).

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