To set up Slack integration go to your Settings page, and select Slack on your left.
First allow Screenshotbot access to your Slack channel by clicking the "Add to Slack" link. This uses OAuth to authenticate Screenshotbot with Slack.
Next, specify the channel on which you want to see notifications, and hit Save.
If you need customized Slack messages or more complex rules (e.g. multiple channels), please reach out to us, and we'll be able to set it up for you.
