By default, data GET requests use to_webhook=true, so data is delivered asynchronously to your configured webhook and the immediate response contains only user metadata, with no data array.

A couple of related points:

• There is no /v2/userdata endpoint. Fetch per type via /v2/sleep, /v2/daily, /v2/body, /v2/activity, /v2/nutrition or /v2/menstruation.

• Each delete-and-readd mints a new terra_user_id, and the old one stops returning data, so always use the latest id. Check user validity with GET /v2/userInfo or /v2/subscriptions.
