# Consul Secrets Engine (API)

@include 'x509-sha1-deprecation.mdx'

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).

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                    |
| :----- | :---------------------- |
| `POST` | `/consul/config/access` |

### 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: "")` – Specifies the Consul ACL token to use. This
  must be a management type token. If this is not provided, Vault will try to
  bootstrap the ACL system of the Consul cluster automatically.

- `ca_cert` `(string: "")` - CA certificate to use when verifying Consul server certificate,
  must be x509 PEM encoded.

- `client_cert` `(string: "")` - Client certificate used for Consul's TLS communication,
  must be x509 PEM encoded and if this is set you need to also set client_key.

- `client_key` `(string: "")` - Client key used for Consul's TLS communication,
  must be x509 PEM encoded and if this is set you need to also set client_cert.

### Sample Payload

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

### Sample Request

```shell-session
$ curl \
    --request POST \
    --header "X-Vault-Token: ..." \
    --data @payload.json \
    http://127.0.0.1:8200/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. At least one of `consul_policies`, `consul_roles`,
`service_identities`, or `node_identities` is required depending on the
Consul version.

| Method | Path                  |
| :----- | :-------------------- |
| `POST` | `/consul/roles/:name` |

### Parameters for Consul versions 1.11 and above

- `partition` `(string: "default")` - Specifies the Consul admin partition in which the token is generated.
  The partition must exist, and the Consul policies or roles assigned to the
  Vault role must also exist inside the given partition. If it's not provided, the partition `default`
  is used.

To create a client token within a particular Consul admin partition:

```json
{
  "partition": "admin1"
}
```

### Parameters for Consul versions 1.8 and above

- `consul_namespace` `(string: "default")` - Specifies the Consul namespace in which the token is generated.
  The namespace must exist, and the Consul policies or roles assigned
  to the Vault role must also exist inside the given Consul namespace. If not provided, the
  namespace `default` is used.

- `node_identities` `(list: <node identity or identities>)` - The list of node identities to assign to the generated
  token. This may be a comma-separated list to attach multiple node identities to a token.

To create a client token within a particular Consul namespace:

```json
{
  "consul_namespace": "ns1"
}
```

To create a client token with node identities attached:

```json
{
  "node_identities": [
      "client-1:dc1",
      "client-2:dc1"
    ]
}
```

### Parameters for Consul version 1.5 and above

  token. This may be a comma-separated list to attach multiple service identities to a token.

  token generated by Vault.

  To create a client token with roles defined in Consul:

### Sample Payload

```json
{
  "consul_roles": "role-a,role-b"
}
```

To create a client token with service identities attached:

```json
{
  "service_identities": [
      "myservice-1:dc1,dc2",
      "myservice-2:dc1"
    ]
