Installation

The oura_ring module can be installed via pip:

pip install oura-ring

Or, using uv:

uv add oura-ring

Getting Started

Note: Personal access tokens were deprecated by Oura in December 2025 — new ones can no longer be created, though previously-issued tokens may still work. New integrations must use OAuth2.

OAuth2 (recommended)

Create an application in Oura's developer portal to obtain a client_id and client_secret. Use OuraAuth to run the Authorization Code flow:

from oura_ring import OuraClient, OuraAuth

oauth = OuraAuth(client_id, client_secret)

# 1. Send the user to the authorization URL to grant access.
url = oauth.authorize_url(
    redirect_uri="https://yourapp.com/callback",
    state="<opaque CSRF value>",
)
# redirect the user to `url`...

# 2. Oura redirects back to your callback with a `?code=...` query param.
#    Exchange that code for tokens.
tokens = oauth.exchange_code(code, redirect_uri="https://yourapp.com/callback")

# 3. Create a client with the access token.
client = OuraClient(access_token=tokens["access_token"])

When the access token expires, refresh it with the refresh token:

tokens = oauth.refresh_token(tokens["refresh_token"])

Important: Refresh tokens are single-use. The refresh response returns a new refresh_token that you must persist — the old one is invalidated, so the next refresh will fail if you don't store the new value.

Refreshing on demand

The client does not refresh automatically — it raises requests.HTTPError when a token has expired (HTTP 401). Catch that, refresh, persist the rotated tokens, and retry. A long-lived service looks roughly like this:

import requests
from oura_ring import OuraClient, OuraAuth

oauth = OuraAuth(client_id, client_secret)

def refresh_and_persist(tokens: dict) -> dict:
    tokens = oauth.refresh_token(tokens["refresh_token"])
    save_tokens(tokens)  # your storage — both access_token AND the new refresh_token
    return tokens

tokens = load_tokens()  # your storage
try:
    sleep = OuraClient(access_token=tokens["access_token"]).get_daily_sleep(...)
except requests.HTTPError as err:
    if err.response.status_code != 401:
        raise
    tokens = refresh_and_persist(tokens)
    sleep = OuraClient(access_token=tokens["access_token"]).get_daily_sleep(...)

Persisting the new refresh_token is the part that bites people: skip it and the next refresh fails with a 400, because Oura invalidated the old one the moment it issued the replacement.

Constructing a client from a token

OuraClient authenticates every request with a bearer token. That token can be an OAuth2 access token or a legacy personal access token, passed either by keyword or positionally:

from oura_ring import OuraClient

# OAuth2 access token (keyword)
client = OuraClient(access_token=token)

# Positionally — a legacy personal access token still works here for
# backwards compatibility.
client = OuraClient(token)

# Using a context manager
with OuraClient(token) as client:
    ...

Loading a token from the environment

It is best practice to store the token in a .env file. The value can be an OAuth2 access token or a legacy personal access token:

# Oura credentials
OURA_ACCESS_TOKEN="<ACCESS_TOKEN>"

You can use python-dotenv to load the environment variables for use in code:

import os
from dotenv import load_dotenv

load_dotenv()

token = os.getenv("OURA_ACCESS_TOKEN") or ""

client = OuraClient(token)

API Requests

There are 19 different API requests that OuraClient can make. Full Oura API v2 documentation can be found on Oura's website.

Scope and limitations (by design): the client returns the API's JSON as-is and raises on HTTP errors (including expired tokens and 429 rate limits) — there is no automatic token refresh or retry built in; use OuraAuth.refresh_token to rotate tokens. The optional fields (sparse fieldsets) query param and the webhook subscription API are intentionally not exposed.

Usage With DataFrame

Using Oura API data with a Pandas DataFrame is very straightforward:

>>> import pandas as pd

>>> sleep = client.get_daily_sleep()
>>> pd.json_normalize(sleep)
