Connecting Polar — setup and troubleshooting

How to connect your Polar account to FitGlue via OAuth.

📅 8 February 2026

Overview

Polar connects to FitGlue via OAuth through the Polar Accesslink API. This allows FitGlue to import activities from your Polar watch.

Authentication Type

OAuth 2.0 — Secure redirect-based authorization.

Setup

  1. Go to FitGlue — Dashboard → Connections → Polar → Connect.
  2. Sign in with your Polar Flow account.
  3. Grant permissions for activity data access.
  4. Verify — Sync an activity from your Polar watch and check it appears.

Common Issues

Token expired — Polar tokens may expire. Reconnect via Dashboard → Connections.

Data not syncing — Ensure your Polar device has synced to Polar Flow first (via Polar Flow app or FlowSync desktop software). FitGlue reads from Polar's cloud, not directly from the device.

Wrong account — If you have multiple Polar accounts, ensure you connect the one linked to your device.
