## subscriber_by_uuid() Retrieve a single subscriber by their UUID (e.g. "c37786af-e6ab-4260-9b49-740adpcm6ed"). Usage ``` python subscriber_by_uuid( subscriber_uuid, timeout_config=None, ) ``` The UUID is matched against `subscribers.uuid` on the server and the first matching subscriber is returned. ## Parameters `subscriber_uuid: str` UUID of the subscriber to look up (e.g. "c37786af-e6ab-4260-9b49-740adpcm6ed"). `timeout_config: Optional[httpx2.Timeout] = None` Optional per-request timeout; defaults to 10 seconds. ## Returns `Optional[models.Subscriber]` The matching models.Subscriber, or None if no subscriber has that UUID. ## Raises `OperationNotAllowedError` If the base URL has not been set or you have not logged in. `ValidationError` If the server returns an empty body or invalid JSON. `httpx2.HTTPStatusError` If the server responds with a 4xx or 5xx status.
