Do you need an Oura Membership to use the API?
If a third-party Oura app suddenly stopped working, this is probably why. Since late 2025, Oura requires an active Membership for API access on Gen 3, Gen 4 and Gen 5 rings — a change that quietly broke a lot of companion apps. Here’s the situation, plainly.

What changed
For years, any Oura owner could connect a third-party app to their data through Oura’s API, Membership or not. That ended in late 2025: API access now requires an active Oura Membership on Gen 3, Gen 4 and Gen 5. The older personal-access-token route that some tools relied on was wound down at the same time.
Which rings are affected
The requirement applies to Gen 3, Gen 4 and Gen 5. Gen 2 is exempt — those rings keep API access without a Membership. So whether you’re affected comes down to which generation you wear: a Gen 2 owner is unaffected, while a Gen 3, Gen 4 or Gen 5 owner now needs an active Membership for any app to read their data.
What it means for third-party apps
Every companion app — desktop tools, analytics dashboards, integrations — reads your data through that same API. So on a current ring, letting your Membership lapse doesn’t just dim Oura’s own app; it cuts off everything built on top of it. It’s worth factoring into the real cost of the ring if companion apps are part of why you bought it.
How to check your access
If a connected app stops syncing, check your Membership status first — an expired Membership is the most common cause now. On a Gen 2 ring, look elsewhere (a re-authorisation or token issue). If you’re shopping for a ring specifically to use with third-party tools, factor the Membership into the running cost on the newer generations.
Vitra connects through the official Oura API, so the same rule applies: on a Gen 3, Gen 4 or Gen 5 you’ll need an active Oura Membership for it to read your data; on a Gen 2 you won’t. Either way, once the data reaches Vitra it’s analysed entirely on your own machine.
