Webhooks Reference

Endpoint	Description
Subscribe To/Unsubscribe From Events	Subscribe to or unsubscribe from events for a specified topic.

Subscribe to or unsubscribe from events for a specified topic.

Web hook response payloads mimic their respective New Twitch API endpoint responses (with minor omissions for unnecessary fields). That is, a call to a web hook returns in its payload the same data as a call to the corresponding endpoint in the new Twitch API.

Also see the Get Webhooks Subscriptions endpoint.

Note: Subscription requests affect rate limits in the new Twitch API.

Authentication

URL

POST https://api.twitch.tv/helix/webhooks/hub

JSON Body Parameters

Name	Type	Description	Required?
`hub.callback`	string	URL where notifications will be delivered.	Yes
`hub.mode`	string	Type of request. Valid values: `subscribe`, `unsubscribe`.	Yes
`hub.topic`	string	URL for the topic to subscribe to or unsubscribe from. `topic` maps to a new Twitch API endpoint. We support these topics: User Follows — Notifies when a follows event occurs. Stream Changed — Notifies when a stream changes; e.g., stream goes online or offline, the stream title changes, or the game changes. User Changed — Notifies when a user changes information about his/her profile.	Yes
`hub.lease_seconds`	int	Number of seconds until the subscription expires. Default: 0. Maximum: 864000. The default (0) allows you to test the subscription-creation workflow without creating any subscriptions (since they expire immediately). After testing, to actually create subscriptions, you must specify a larger value.	No
`hub.secret`	string	Secret used to sign notification payloads. The `X-Hub-Signature` header is generated by `sha256(secret, notification_bytes)`. We strongly encourage you to use this, so your application can verify that notifications are genuine.	No
