Understand when to use DocuSign Rooms vs. eSignature and choose the right API

Steps

1. Use DocuSign Rooms API when your workflow involves real estate transactions — Rooms is a deal-room product specific to real estate closings, with forms libraries (MISMO, state-specific), task management, and multi-party transaction coordination.
2. Use the DocuSign eSignature API (the standard product) for general-purpose document signing workflows across any industry — contracts, HR onboarding, NDAs, sales agreements, and any non-real-estate use case.
3. Authenticate to both APIs using the same DocuSign OAuth 2.0 infrastructure at account.docusign.com; however, the Rooms API requires separate JWT or OAuth scopes that include 'dtr.rooms.read' and 'dtr.rooms.write'.
4. The Rooms API base URL follows https://www.docusign.net/restapi/rooms/v2 (production) — note it is a different path than the eSignature API base URL; sandbox uses demo.docusign.net.
5. For hybrid workflows (create a room AND send a document for signature), you can link a Rooms transaction to an eSignature envelope — use the Rooms API to create the room and the eSignature API to create the envelope, then associate them via the Rooms document endpoint.
6. Check that your DocuSign plan includes the Rooms product — it is not included in all DocuSign tiers and requires a separate entitlement; calling Rooms endpoints with a non-entitled account returns authorization errors.
