# Register Client

`POST /oauth/register`

## Request

- Base URL: `https://api.actuato.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.actuato.com/oauth/register`
- Auth: none declared

## Request body

- ClientRegistration: RFC 7591 dynamic client registration request (the subset MCP clients send).
  - `redirect_uris` string[], required
  - `client_name` string, nullable
  - `client_uri` string, nullable
  - `logo_uri` string, nullable
  - `software_id` string, nullable
  - `software_version` string, nullable
  - `grant_types` string[]
  - `response_types` string[]
  - `token_endpoint_auth_method` string
  - `scope` string, nullable

## Response `201`

Successful Response

- ClientInformation: RFC 7591 registration response. Fields with no value are left out rather than sent as null: some clients (ChatGPT among them) reject `"client_secret": null` from a public client. client_secret_expires_at is sent only alongside a secret, as the RFC requires.
  - `client_id` string, required
  - `client_secret` string, nullable
  - `client_id_issued_at` integer, required
  - `client_secret_expires_at` integer, nullable
  - `redirect_uris` string[], required
  - `client_name` string, nullable, required
  - `client_uri` string, nullable, required
  - `logo_uri` string, nullable, required
  - `grant_types` string[], required
  - `response_types` string[], required
  - `token_endpoint_auth_method` string, required
  - `scope` string, required
