This is incredibly powerful: it increases the number of inputs and nodes to Slack. Slack is impressive for being one of the first enterprise products to experience consumer-like virality, and is quickly moving towards being a verb (“Slack it!”)
However, the Slack Button doesn’t currently allow you to embed the button on a webpage to quickly share that link (like the ubiquitous Facebook and Twitter share buttons). I can understand the app-centric approach that SlackHQ took in building the Slack Button, so I thought it would be a cool project to extend the Add to Slack functionality to webpages in the form of two products:
My brother Richard and I hacked this together in a day, and we wanted to share the product with you all.

This Unofficial Slack Button is a 24-hour hack by fans of Slack, and is in no way affiliated with Slack Technologies.
Copy and paste that on any page, and it’ll give you a button that looks like this:
By default, the button autopopulates the composer with the URL the button lives on.
If you want to customize the url the button auto-populates in the composer, add the following:
to the <a> tag. This is helpful for example when you’re using this button in a template.
The first time a user clicks the Slack button, it will prompt them to OAuth to the Slack team they want to post to.
After that, the button will then pop-up a Composer window, and auto-fill the form with a link.
Due to the way the Slack OAuth API is set up, we couldn’t find an easy way to allow multiple Slack team auths with different email addresses associated with those teams.
So for now, you’ll have to log out and re-auth if you want to post to a different team. If you’ve already logged in to multiple accounts on your browser, it theoretically should give you a team selector for which team you’d like to auth for the button.
The flow makes it easy for you to log out either on the composer page or on the post confirmation page, if you want to re-post to a different team.
