# 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).

!!! 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 <span style="background:#ff8000;width:.9em;height:.9em;display:inline-block;vertical-align:middle"></span><code>#ff8000</code> would be `%23ff8000` etc.
