Twitch API Guide
The Twitch API provides the tools and data used to develop integrations with Twitch. The data models and systems are designed to provide relevant data in an easy, consistent, and reliable way.
API endpoint support for JSONP has been removed.
Request parameters are &-repeated (e.g.,
&login=&login=&login=), not comma-separated as in the deprecated Twitch API v5.
With the Twitch API, our philosophy for responses is to remove extraneous data, return consistent structures, and simplify responses to a single layer. While simplifying the data models, we observed a lot of overlap between users and channels objects; as a result, we combined them into the user object.
To prevent our API from being overwhelmed by too many requests, Twitch rate-limits requests. A token bucket algorithm is used, where a token (aka point) counts for a request. The refill rate is set on a steady-state rate and the burst is the maximum bucket size.
Each client ID has a point-refill rate of 800 points per minute per user and a bucket size of 800 points.
|Authentication||Refill Rate||Bucket Size|
|Bearer token is provided||800 points per minute, per user||800 points|
|Bearer token is not provided||30 points per minute||30 points|
The limit is across all Twitch API queries. If this limit is exceeded, an error is returned: HTTP 429 (Too Many Requests).
When you make an API request, you will receive a set of rate-limiting headers to help your application respond appropriately. The headers are:
Ratelimit-Limit: The rate at which points are added to your bucket. This is the average number of requests per minute you can make over an extended period of time.
Ratelimit-Remaining: The number of points you have left to use.
Ratelimit-Reset: A Unix epoch timestamp of when your bucket is reset to full.
Individual endpoints may have additional rate limits, with additional headers to describe those limits. For details, see the documentation for each endpoint.
Individual endpoints are given a point value. When an endpoint is called, the point value of the endpoint is subtracted from the total points granted to your client ID. The default point value is 1; i.e., a point is equivalent to a request. Currently all endpoints have the same point value.
The Twitch API includes a webhook system that allows you to subscribe to a topic and be notified when new data comes in for that topic. This helps to alleviate the need to poll the API for fresh data. With each release, we add more topics.
The Twitch API uses the existing Twitch authentication system, and it allows the use of application tokens for API calls. These application tokens allow you to make an API request on behalf of your application rather than on behalf of a user.
The header differs, depending on whether you use the Twitch API or the deprecated Twitch API v5. See Sending User Access and App Access Tokens in the Apps & Authentication Guide.
Service Unavailable Error
If you get an HTTP 503 (Service Unavailable) error, retry once. If that retry also results in an HTTP 503, there probably is something wrong with the downstream service. Check the status page for relevant updates.
The Twitch API has a public status page. You will find aggregate information about service health and incidents. You can subscribe to this page, to get automated alerts around this data.
