  description: "# Overview \nThe Oura API allows Oura users and partner applications to improve their user experience with Oura data.\nThis document describes the Oura API Version 2 (V2), which is the only available integration point for Oura data. The previous V1 API has been sunset.\n# Getting Started \n## What is an API?\nAn API (Application Programming Interface) allows different software applications to communicate with each other. The Oura API enables you to access your Oura Ring data programmatically.\n## Quick Start Guide\n1. Register an [API Application](https://cloud.ouraring.com/oauth/applications) and implement OAuth2\n2. **Make Your First API Call**:\n   ```\n   curl -X GET https://api.ouraring.com/v2/usercollection/personal_info \\\n   -H \"Authorization: Bearer YOUR_TOKEN_HERE\"\n   ```\n3. **Explore Data Types**:\n   - Browse the available endpoints in this documentation to discover what data you can access\n   - Each endpoint includes example requests and responses\n4. **Set Up Webhooks (Strongly Recommended)**:\n   - Webhooks are the preferred way to consume Oura data\n   - We have not had customers hit rate limits with webhooks properly implemented\n   - Make a single request for historical data when a user first connects, then use webhooks for ongoing updates\n   - Webhook notifications come approximately 30 seconds after data syncs from the mobile app\n   - [Set up webhooks](#tag/Webhook-Subscription-Routes) to receive notifications when data changes\n## Common Questions\n- **Data Delay**: Different data types sync at different times - sleep data requires users to open the Oura app, while daily activity and stress may sync in the background\n# Data Access\nIn order to access data, a registered [API Application](https://cloud.ouraring.com/oauth/applications) is required.\n API Applications are limited to **10** users before requiring approval from Oura. There is no limit once an application is approved.\n Additionally, Oura users **must provide consent** to share each data type an API Application has access to.\nAll data access requests through the Oura API require [Authentication](https://cloud.ouraring.com/docs/authentication).\nAdditionally, we recommend that Oura users keep their mobile app updated to support API access for the latest data types.\n# Authentication\nThe Oura Cloud API supports authentication through the industry-standard OAuth2 protocol. For more information, see our [Authentication instructions](https://cloud.ouraring.com/docs/authentication).\nAccess tokens must be included in the request header as follows:\n```http\nGET /v2/usercollection/personal_info HTTP/1.1\nHost: api.ouraring.com\nAuthorization: Bearer <token>\n```\nPlease note that personal access tokens were deprecated in December 2025 and are no longer available for use.\n# Oura HTTP Response Codes\n| Response Code                        | Description |\n| ------------------------------------ | - |\n| 200 OK                               | Successful Response         |\n| 400 Query Parameter Validation Error | The request contains query parameters that are invalid or incorrectly formatted. |\n| 401 Unauthorized                     | Invalid or expired authentication token. |\n| 403 Forbidden                        | The requested resource requires additional permissions or the user's Oura subscription has expired. |\n| 429 Too Many Requests                | Rate limit exceeded. See response headers for retry guidance. |\n\n## Rate Limits\nThe API enforces rate limits at two layers to ensure fair access across all applications:\n- a per-access-token limit, which throttles single-token floods, and\n- a per-application limit, which caps the aggregate traffic across all of an application's end-user tokens so one fan-out app can't dominate shared capacity.\n\nA request that trips either layer receives a `429 Too Many Requests`. The `X-RateLimit-Tier` response header identifies which layer fired.\n\nIf your application regularly approaches rate limits, [webhooks](#tag/Webhook-Subscription-Routes) are strongly recommended — most applications that implement webhooks correctly do not encounter rate limit issues.\n\n[Contact us](mailto:api-support@ouraring.com) if you expect your usage to require higher limits.\n\n## Rate Limit Response Headers\nWhen a `429 Too Many Requests` response is returned, five headers are included to guide retries. Prefer these over fixed-interval backoff:\n- **`Retry-After`** — integer seconds to wait before retrying. RFC 7231-compliant; safe to feed directly into your client's backoff logic.\n- **`X-RateLimit-Limit`** — the request ceiling for the current window.\n- **`X-RateLimit-Window`** — the rolling window length in seconds that the ceiling applies to.\n- **`X-RateLimit-Reset`** — Unix epoch (seconds) at which the window resets and quota is fully restored.\n- **`X-RateLimit-Tier`** — identifies which limit was exceeded, useful when contacting support.\n"
