# Consul Secrets Engine (API)

This is the API documentation for the Vault Consul secrets engine. For general
information about the usage and operation of the Consul secrets engine, please
see the [Vault Consul documentation](/docs/secrets/consul/index.html).

This documentation assumes the Consul secrets engine is enabled at the `/consul`
path in Vault. Since it is possible to enable secrets engines at any location,
please update your API calls accordingly.

## Configure Access

This endpoint configures the access information for Consul. This access
information is used so that Vault can communicate with Consul and generate
Consul tokens.

| Method   | Path                         | Produces               |
| :------- | :--------------------------- | :--------------------- |
| `POST`   | `/consul/config/access`      | `204 (empty body)`     |

### Parameters

- `address` `(string: <required>)` – Specifies the address of the Consul
  instance, provided as `"host:port"` like `"127.0.0.1:8500"`.

- `scheme` `(string: "http")` – Specifies the URL scheme to use.

- `token` `(string: <required>)` – Specifies the Consul ACL token to use. This
  must be a management type token.

### Sample Payload

```json
{
  "address": "127.0.0.1:8500",
  "scheme": "https",
  "token": "adha..."
}
```

### Sample Request

```
$ curl \
    --request POST \
    --header "X-Vault-Token: ..." \
    --data @payload.json \
    https://vault.rocks/v1/consul/config/access
```

## Create/Update Role

This endpoint creates or updates the Consul role definition. If the role does
not exist, it will be created. If the role already exists, it will receive
updated attributes.

| Method   | Path                         | Produces               |
| :------- | :--------------------------- | :--------------------- |
| `POST`   | `/consul/roles/:name`        | `204 (empty body)`     |

### Parameters

- `name` `(string: <required>)` – Specifies the name of an existing role against
  which to create this Consul credential. This is part of the request URL.

- `lease` `(string: "")` – Specifies the lease for this role. This is provided
  as a string duration with a time suffix like `"30s"` or `"1h"`. If not
  provided, the default Vault lease is used.

- `policy` `(string: <required>)` – Specifies the base64 encoded ACL policy. The
  ACL format can be found in the [Consul ACL
  documentation](https://www.consul.io/docs/internals/acl.html). This is
  required unless the `token_type` is `management`.

- `token_type` `(string: "client")` - Specifies the type of token to create when
  using this role. Valid values are `"client"` or `"management"`.

### Sample Payload

To create management tokens:

```json
{
  "token_type": "management"
}
```

To create a client token with a custom policy:

```json
{
  "policy": "abd2...=="
}
```
