Integrations: Strava, Wahoo, WHOOP, Garmin

Planned workout uploads: how they work

For step-by-step device upload (toggle defaults, Send to app, and syncing the head unit), see Upload planned workouts to Garmin or Wahoo.

If you enable workout upload for Wahoo or Garmin on /settings/integrations:

• N+One uploads planned sessions so the workout appears on your device or in Garmin Connect / Wahoo device memory.
• Uploads are session-level planned workouts (interval structure) generated from the plan. The device executes the workout while you ride.
• If a planned session is later matched to a completed activity, N+One will deduplicate the calendar view so you see the completed activity with planned context.

Note: Zwift workout upload is a planned feature (coming soon). Do not expect in-app Zwift uploads today.

OAuth: connect, return, and messages you may see

Connections use OAuth. After you authorize a provider you’ll be redirected back to N+One and the return URL can include status messages.

Common query messages you might see on return:

• success — authorization completed and the integration is connected.
• oauth_failed — the OAuth flow failed. Try reconnecting (steps below).
• whoop_profile_failed — WHOOP profile lookup failed after auth. Try reconnecting; if the problem persists, contact support.
• unauthorized — the authorization was declined or expired.

If you see an error message in the URL after returning from a provider, go to /settings/integrations and try reconnecting for that provider.

Managing connections

• To connect: open Settings → Device Integrations (/settings/integrations), choose the provider, and follow the OAuth prompts.
• To reconnect: use the same flow from /settings/integrations. If a provider reports an OAuth error, try disconnecting and connecting again.
• To disconnect: open /settings/integrations and use the disconnect action for that provider. Disconnecting removes the active link between accounts; previously synced activities remain in your account unless explicitly deleted.
• Check the integration card for "last sync" and sync status after connecting. It may take a few minutes for recent activities to appear.

Duplicates, matching, and commute rides

• Training sessions come from synced integrations and planned workouts. N+One attempts to match planned sessions with completed rides; when matched, the UI deduplicates entries on the Training calendar (/training).
• If you see apparent duplicates, open the session detail (/training/[id]) to inspect whether one entry is a planned session and the other is a completed activity.
• Commute activities: Strava’s commute flag (or activity metadata) can be excluded when your profile preference "exclude commute activities" is enabled. That preference is default‑on in code paths; you can change it in /settings/profile.

Sync frequency and offline behavior

• Integrations use background sync via the provider’s API. The Device Integrations page shows last sync time.
• New synces and the AI Coach require network access. If you’re offline, previously viewed pages may work from cache; visit /offline for details about which pages are uncached or limited.
• The app runs as a PWA and may prompt you to install it; see /install-pwa for the install guide.

Troubleshooting checklist

If an integration isn’t behaving as expected, try these steps in order:

1. Confirm your connection on /settings/integrations and check the card for errors or "last sync" time.
2. Reconnect the service from /settings/integrations. Complete the OAuth flow and look for a success return.
3. If an OAuth error appears (oauth_failed, unauthorized, whoop_profile_failed), try disconnecting and reconnecting. Check that you allowed the requested permissions on the provider’s side.
4. Ensure your browser allows popups and third‑party cookies for the OAuth flow. Private/incognito windows sometimes block the flow.
5. Check your network. Some features (AI Coach, new syncs) require a live connection.
6. Verify the profile preference "exclude commute activities" in /settings/profile if rides appear missing.
7. If planned workouts don’t appear on your device after enabling uploads, confirm you enabled the upload toggle on the Wahoo or Garmin integration card and wait a few minutes for the push to complete.
8. If data still doesn’t appear, open /settings/support to report the issue and include the provider name, the error message shown, and the approximate timestamp of your last attempted sync.

Privacy and data notes

Integrations share data with N+One according to the permissions you grant during OAuth. See /settings/privacy or our public /privacy page for details on how we store and use integration data.

When to contact support

Use /settings/support if:

• An integration repeatedly fails to connect after retrying.
• You see unexplained OAuth error codes after reconnect attempts.
• Planned workout upload isn’t reaching your Wahoo or Garmin device after enabling the toggle.

Provide timestamps and screenshots when possible; it speeds diagnosis.

Quick first‑time connect flow

1. Open the profile menu → Settings → Device Integrations (/settings/integrations).
2. Choose Strava, Wahoo, WHOOP, or Garmin and follow the OAuth prompts.
3. After returning, confirm the integration card shows a recent "last sync" and no error messages.
4. If you want planned sessions on device, enable workout upload on the Wahoo or Garmin integration card.
5. Check Training (/training) to see synced activities and how they match planned sessions.
