# Slack
## Sending messages using incoming webhooks
Incoming webhooks are a way to post messages from **Widgelix** into **Slack**. Creating an incoming webhook gives you a unique URL to which you send your notifications. You can use all the usual [formatting](https://api.slack.com/reference/surfaces/formatting) to make the messages stand out.
The setup is straightforward - you create a Slack App and then use it to generate a unique webhook URL. Follow the steps in this article to obtain the URL for **Slack** notifications.
### Create a Slack app (if you don't have one already)
[Create your Slack app](https://api.slack.com/apps/new)
Pick a name, choose a workspace to associate your app with (bear in mind you'll probably be posting lots of test messages, so you may want to create a channel for sandbox use), then click **Create New App** and choose **from scratch**. If you've already created an app, you can use that one.
### Enable incoming webhooks
You'll be redirected to the settings page for your new app (if you're using an existing app, you can load its settings via your [app's management dashboard](https://api.slack.com/apps)).
From here, select **Incoming Webhooks**, and toggle **Activate Incoming Webhooks** to on.
### Create an incoming webhook
Now that incoming webhooks are enabled, the settings page should refresh and some additional options will appear. One of those options is a very helpful button called **Add New Webhook to Workspace** — click it!
What this button does is trigger a shortcut version of the installation flow for Slack apps, one that is completely self-contained so that you don't have to actually build any code to generate an incoming webhook URL. You'll see something like the following:
Go ahead and pick a channel that the app will post to, then select **Authorize**. If you need to add the incoming webhook to a private channel, you must first be in that channel.
You'll be sent back to your app settings, where you should see a new entry under the **Webhook URLs for Your Workspace** section. Your webhook URL will look something like this:
```http
https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX
```
That URL is your new incoming webhook, one that's specific to a single user and a single channel.
Let's see how you can actually use that webhook to post a message.
**Keep it secret, keep it safe**. Your webhook URL contains a secret. Don't share it online, including via public version control repositories. **Slack actively searches out and revokes leaked secrets.**
### Using webhook URL in you Widgelix's Rule
Go to your created rule, and paste your Slack Webhook URL into URL field of Slack notification option:
