# 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).
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.
- `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.
| Method | Path |
| :----- | :-------------------- |
| `POST` | `/consul/roles/:name` |
### Parameters for Consul versions 1.7 and above
- `consul_namespace` `(string: "")` <EnterpriseAlert inline /> - Specifies the Consul namespace the token
will be generated within. The namespace must exist, and the policies or roles assigned to the
Vault role must also exist inside the given Consul namespace. If not provided, the "default"
namespace is used.
### Parameters for Consul versions 1.11 and above
- `partition` `(string: "")` <EnterpriseAlert inline /> - Specifies the Consul admin partition the token
will be generated within. The partition must exist, and the policies or roles assigned to the
Vault role must also exist inside the given partition. If not provided, the "default"
partition is used.
To create a client token within a particular Consul namespace:
```json
{
"consul_namespace": "ns1"
}
```
To create a client token within a particular Consul admin partition:
```json
{
"partition": "admin1"
}
```
### Parameters for Consul versions 1.4 and above
- `name` `(string: <required>)`  Specifies the name of an existing role against
which to create this Consul credential. This is part of the request URL.
- `token_type` `(string: "client")` - Specifies the type of token to create when
using this role. Valid values are `"client"` or `"management"`. If a `"management"`
token, the `policy`, `policies`, and `consul_roles` parameters are not required.
Defaults to `"client`".
- `policy` `(string: <policy>)` Specifies the base64-encoded ACL policy. This is
required unless the `token_type` is `"management"`. [Deprecated as of Consul 1.4 and
removed as of Consul 1.11.](https://www.consul.io/api/acl/legacy)
- `policies` `(list: <policy or policies>)` The list of policies to assign to the
generated token. Either `policies` or `consul_roles` are required for Consul 1.5 and
above, or just `policies` if using Consul 1.4.
- `consul_roles` `(list: <role or roles>)` The list of Consul roles to assign to the
generated token. Either `policies` or `consul_roles` are required for Consul 1.5 and above.
- `local` `(bool: false)` - Indicates that the token should not be replicated
globally and instead be local to the current datacenter. Only available in Consul
1.4 and greater.
- `ttl` `(duration: "")`  Specifies the TTL for this role. This is provided
as a string duration with a time suffix like `"30s"` or `"1h"` or as seconds. If not
provided, the default Vault TTL is used.
- `max_ttl` `(duration: "")`  Specifies the max TTL for this role. This is provided
as a string duration with a time suffix like `"30s"` or `"1h"` or as seconds. If not
provided, the default Vault Max TTL is used.
### Sample Payload
To create management tokens:

{
"token_type": "management"
}
```
To create a client token with defined policies:
```json
{

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