 # Incoming Webhooks
 
-Incoming webhooks allow external applications to post messages into Mattermost channels and private groups by sending a specifically formatted JSON payload via HTTP POST request to a secret Mattermost URL generated specifically for each application. 
+Incoming webhooks allow external applications, written in the programming language of your choice--to post messages into Mattermost channels and private groups by sending a specifically formatted JSON payload via HTTP POST request to a secret Mattermost URL generated specifically for each application.

  1. Login to your Mattermost team site and go to **Account Settings -> Integrations**

+     2. In addition, with **Enable Overriding of Usernames from Webhooks** turned on,  you can also override the username the message posts as by providing a `username` parameter in your JSON payload. For example, you might want your message looking like it came from a robot so you can use ```payload={"username": "robot", "text": "Hello, this is some text."}``` to change the username of the post to robot. Note, to combat any malicious users from trying to use this to perform [phishing attacks](https://en.wikipedia.org/wiki/Phishing) a `BOT` indicator appears next to posts coming from incoming webhooks.
+     3. With **Enable Overriding of Icon from Webhooks** turned on, you can similarly change the icon the message posts with by providing a link to an image in the `icon_url` parameter of your payload. For example, ```payload={"icon_url": "http://somewebsite.com/somecoolimage.jpg", "text": "Hello, this is some text."}``` will post using whatever image is located at `http://somewebsite.com/somecoolimage.jpg` as the icon for the post.

+ 2. Set up your integration running on your own machine or a hosting service like AWS or Heroku, to start sending real time updates to Mattermost channels and private groups.

+As mentioned above, Mattermost makes it easy to take integrations written for Slack's proprietary JSON payload format and repurpose them to become Mattermost integrations. The following automatic translations are supported: 
 
 1. Payloads designed for Slack using `<>` to note the need to hyperlink a URL, such as ```payload={"text": "<http://www.mattermost.com/>"}```, are translated to the equivalent markdown in Mattermost and rendered the same as you would see in Slack. 
 2. Similiarly, payloads designed for Slack using `|` within a `<>` to define linked text, such as ```payload={"text": "Click <http://www.mattermost.com/|here> for a link."}```, are also translated to the equivalent markdown in Mattermost and rendered the same as you would see in Slack. 
+3. Like Slack, by overriding the channel name with an @username, such as payload={"text": "Hi", channel: "@jim"}, you can send the message to a user through your direct message chat.
+4. Channel names can be prepended with a #, like they are in Slack incoming webhooks, and the message will still be sent to the correct channel.
