# Channel Webhook Resource

> \[!CAUTION]

> Programmable Chat has been deprecated and is no longer supported. Instead, we'll be focusing on the next generation of chat: Twilio Conversations. Find out more about the [EOL process here](https://www.twilio.com/en-us/changelog/programmable-chat-end-of-life-notice).

A Channel Webhook resource describes a webhook target that is specific to a [Channel](/docs/chat/channels). By default, events in a Programmable Chat instance are delivered to a webhook address that is specified for the whole Chat [Service](/docs/chat/rest/service-resource). However, you can use this resource to specify up to five unique webhook targets for each channel to handle exceptional cases.

The webhook target can be a Web URL or a Studio Flow.
