# Slack
!!! attention "New URL format"
The URL format for Slack has been changed to allow for API- as well as webhook tokens.
Using the old format (`slack://xxxx/yyyy/zzzz`) will still work as before and will automatically be upgraded to
the new format when used.
The Slack notification service uses either [Slack Webhooks](https://api.slack.com/messaging/webhooks) or the
[Bot API](https://api.slack.com/methods/chat.postMessage) to send messages.
See the [guides](../guides/slack/index.md) for information on how to get your *token* and *channel*.
## URL Format
!!! note ""
Note that the token uses a prefix to determine the type, usually either `hook` (for webhooks) or `xoxb` (for bot API).
--8<-- "docs/services/slack/config.md"
!!! info "Color format"
The format for the `Color` prop follows the [slack docs](https://api.slack.com/reference/messaging/attachments#fields)
but `#` needs to be escaped as `%23` when passed in a URL.
So #ff8000
would be `%23ff8000` etc.
