Powering Slack interactivity with Knock

If you're brand new to building Slack interactive notifications, this Slack guide on building actionable notifications is a great place to learn the basics.

Designing interactive Slack notification templates

To build an interactive Slack message, whether it contains a button, a dropdown, or some other input, you'll be using Slack's block kit UI framework. We cover how to build block-based Slack notifications within Knock in our guide on designing Slack templates.

Handling interaction payloads from Slack

When a button in your interactive Slack notification is clicked, Slack will send an interaction payload to your app. To handle these interaction payloads you'll need to configure your Slack app with a Request URL. You can do this on the app config page of your Slack app. Go to the Interactivity & Shortcuts page of your Slack app and add your Request URL.
