# description
POST /oauth/register — RFC 7591 dynamic client registration. Register once per installation (a plugin registers itself per site) and keep the returned client_id; there is no secret to store.

# properties.redirect_uris.description
Where the authorization code is delivered. Every entry must be an absolute https URL — http is accepted only on loopback, for local development. A javascript: or data: URI is rejected.

# properties.client_name.description
Human-readable name shown to the user on the consent screen. Include the site or install it belongs to so someone with several connections can tell them apart.
