# Create Admin Yamato Root Ca

`POST /v1/admin/yamato/proxy/root-ca`

Create a provider's shared proxy root CA if it does not exist.

Idempotent and first-writer-wins: an existing root is returned unchanged and
is never replaced, so envs that already trust it stay valid.

## Query parameters

- `provider` string, nullable

## Response `200`

Successful Response

- object

## Other responses

- `422` — Validation Error
