New Twitch API Guide

Introduction

The new 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.

Requests

API endpoint support for JSONP has been removed.

Request parameters are &-repeated (e.g., &login=&login=&login=), not comma-separated as in Twitch API v5.

Data Models

With the new Twitch API, we revisited all our data models. Our philosophy for responses was to remove extraneous data, return consistent structures, and simplify responses to a single layer. This removes the deeply-nested structures of the prior API, provides faster response times, and provides flexibility for optimizing API calls. 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.

Rate Limits

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 and bucket size which depend on whether a bearer token is provided:

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 New 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:

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. (All New Twitch API endpoints have the default point value. In the future, if an endpoint has a higher point value, that will be covered in the reference documentation for the endpoint.)

If you need a higher rate limit, please fill out the form at https://dev.twitch.tv/limit-increase.

Webhooks

The new 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.

Authentication

The new 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 new Twitch API or 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.

Status Page

The new 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.
