Interactive buttons are some of the features that only work if you use the Slack app. One of the reasons for this is that you need a place to configure the URL of your script for Slack to send a request when someone clicks a button. It will also work with webcams, but only if the webhook is also part of the Slack application. It will not work with a simple user website.
To make a Slack app for your Slack team, you need to complete two steps.
- Create a new Slack application (for example, on this page )
- Install the Slack app on your Slack Oath Team. (See here )
Please note that you do not need to publish your Slack app in the Slack App directory. It's not obligatory.
