Hasin Hayder has posted a tutorial to his site showing you how to create a bot for Slack that will monitor your sales on Envato connected via their API.

Slack is awesome. Slack is the de-facto of modern team communication and I am pretty sure that this is not the first time you’re hearing something like this about slack. But if you’re really never used slack, oh boy, I feel pity for you. Anyway, in this article we’re going to make a slack bot that will monitor the sales in our envato account and notify from time to time as soon as someone purchased an item. Pretty useful, eh?

He shows how to make a new channel in your Slack instance (he uses "#sales") and how to add in a named webhook to connect the bot to. He then generates a token on the Envato service to access their API, giving it the needed permissions. He includes the simple curl-based script to make the request to the Envato API to get the latest results and then turn around and post it back to the Slack channel.
