# TLS Certificate Auth Method (API)

This is the API documentation for the Vault TLS Certificate authentication
method. For general information about the usage and operation of the TLS
Certificate method, please see the [Vault TLS Certificate method documentation](/docs/auth/cert.html).

This documentation assumes the TLS Certificate method is mounted at the
`/auth/cert` path in Vault. Since it is possible to mount auth methods at any
location, please update your API calls accordingly.

## Create CA Certificate Role

Sets a CA cert and associated parameters in a role name.

| Method   | Path                         | Produces               |
| :------- | :--------------------------- | :--------------------- |
| `POST`   | `/auth/cert/certs/:name`     | `204 (empty body)`     |

### Parameters

- `name` `(string: <required>)` - The name of the certificate role.
- `certificate` `(string: <required>)` - The PEM-format CA certificate.
- `allowed_names` `(string: "")` - Constrain the Common and Alternative Names in
  the client certificate with a [globbed pattern]
  (https://github.com/ryanuber/go-glob/blob/master/README.md#example). Value is
  a comma-separated list of patterns.  Authentication requires at least one Name matching at least one pattern.  If not set, defaults to allowing all names.
- `policies` `(string: "")` - A comma-separated list of policies to set on tokens
  issued when authenticating against this CA certificate.
- `display_name` `(string: "")` -   The `display_name` to set on tokens issued
  when authenticating against this CA certificate. If not set, defaults to the
  name of the role.
- `ttl` `(string: "")` - The TTL period of the token, provided as a number of
  seconds. If not provided, the token is valid for the the mount or system
  default TTL time, in that order.
