# 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. ## Examples !!! example "Bot API" ```uri slack://xoxb:123456789012-1234567890123-4mt0t4l1YL3g1T5L4cK70k3N@C001CH4NN3L?color=good&title=Great+News&icon=man-scientist&botname=Shoutrrrbot ``` !!! example "Webhook" ```uri slack://hook:WNA3PBYV6-F20DUQND3RQ-Webc4MAvoacrpPakR8phF0zi@webhook?color=good&title=Great+News&icon=man-scientist&botname=Shoutrrrbot ```
