Connect an Oura Ring via OAuth2 — app registration, token exchange, and credential storage
Connect the user's Oura Ring to pull sleep, heart rate, readiness, activity, and other health data via the Oura Cloud API V2.
Have the user go to https://developer.ouraring.com/applications and create a new application:
http://localhost:3000/callbackpersonal, daily, heartrate, sleep, workout, spo2, stress, heart_health, session, ring_configurationSave the Client ID and Client Secret.
Store the client secret securely using assistant credentials prompt, then write and run the OAuth helper script on the user's machine:
#!/usr/bin/env python3
"""Oura Ring OAuth2 helper — catches auth code and exchanges for tokens instantly."""
from http.server import HTTPServer, BaseHTTPRequestHandler
from urllib.parse import urlparse, parse_qs, urlencode

CLIENT_SECRET = 'YOUR_CLIENT_SECRET'

class Handler(BaseHTTPRequestHandler):
def do_GET(self):

Run with python3 /path/to/script.py on the user's machine (host_bash). The user authorizes in their browser, the script catches the code and exchanges it for tokens in under a second.
Important: Auth codes expire in ~30 seconds. Do NOT have the user paste codes manually — use this script to catch and exchange them automatically.
After the OAuth flow, read tokens from /tmp/oura_tokens.json and store them:
access_token — store in credential vault with injection template for api.ouraring.com Authorization header (Bearer prefix) and allowed_tools: ["bash"]refresh_token — store in credential vault for token refreshTest with the personal info endpoint:
curl -s -H "Authorization: Bearer $TOKEN" "https://api.ouraring.com/v2/usercollection/personal_info"
All endpoints use GET https://api.ouraring.com/v2/usercollection/{type} with query params start_date and end_date (YYYY-MM-DD format).
| Endpoint | Data | Notes |
|---|---|---|
/v2/usercollection/daily_sleep | Sleep score, duration, efficiency, stages | Best checked after user's typical wake time |
/v2/usercollection/sleep | Detailed sleep periods with HR, HRV, movement | Raw sleep period data |
/v2/usercollection/daily_readiness | Readiness score, HRV balance, recovery | Good morning check-in metric |
/v2/usercollection/daily_activity | Steps, calories, movement, inactivity | Activity summary |
/v2/usercollection/heartrate | Continuous HR (use start_datetime/end_datetime in ISO format) | Can be large — limit date range |
/v2/usercollection/daily_spo2 | Blood oxygen levels | Nightly average |
/v2/usercollection/daily_stress | Stress score and recovery | Daytime stress tracking |
/v2/usercollection/workout | Detected workouts with HR, calories | Auto-detected or manual |
/v2/usercollection/personal_info | Age, weight, height, email | Good connection test |
Tokens expire after 30 days. Refresh with:
curl -s -X POST "https://api.ouraring.com/oauth/token" \
-d "grant_type=refresh_token&refresh_token=$REFRESH_TOKEN&client_id=$CLIENT_ID&client_secret=$CLIENT_SECRET"
Store the new access_token and refresh_token from the response.
