https://www.helprange.com/api/v2/data-roomsCreates a data room, like "New data room" in the panel, with optional folders (one level – no folders inside folders) and settings. Defaults: watermark on, download off, no screenshot protection, guest notifications on, no NDA, no expiry (a default the plan does not include is left off; a setting you ASK for that the plan does not include: 402 naming the plan). The name must be unique in the team (400). Pro: up to 3 active rooms (402 when the limit is reached); Max, Unlimited, the Deal Room Pass and the trial: unlimited. Next: add documents (Add documents to a data room) and invite guests (Invite a guest) – invitations go out once the room has a document. Answers 201 with the room, including links.guest_link.
Plans: Pro, Max, Unlimited, Deal Room Pass, trial. Auth: Authorization: Bearer hr_live_… (team key), X-API-Key, Authorization: Api-Key <key> or an OAuth Bearer token. Scope: rooms:write. Operation id: createDataRoom
Header Idempotency-Key (optional, up to 255 characters): retry with the same key and body within 24 hours and you get the first response back (Idempotent-Replayed: true) – the request is not run twice. Another body: 422 idempotency_key_reused; still running: 409 idempotency_key_in_progress. More.
Content types: application/json, application/x-www-form-urlencoded.

| Status | Description |
|---|---|
201 | Created |
400 | Invalid input – the message says which parameter. |
401 | Missing or invalid API key / OAuth token. Team keys: code invalid_key, key_revoked, key_expired or key_owner_removed. |
402 | Your plan does not include the REST API (the Free plan) or this feature (e.g. NDA needs Max). |
403 | The team API key lacks the scope this endpoint needs. |
405 | Wrong HTTP method for this endpoint. |
409 | The data room is frozen, the signed PDF is not ready yet, (webhooks) the team already has an endpoint / the endpoint is turned off, or (code idempotency_key_in_progress) a request with the same Idempotency-Key is still running – retry in a few seconds. |
422 | code idempotency_key_reused: this Idempotency-Key was already used in the last 24 hours with a different request (method, path or body). Use a new key for a new request. |
429 | A usage limit was reached – wait Retry-After seconds. |

}Uses your real account. The request goes from your browser straight to www.helprange.com with your API key and acts as you – this POST changes data. The key stays in this page (in this tab's session storage only if you tick the box), is never put in a URL and is not sent to analytics. Do not paste a key on a shared computer.
