Verifying requests from Slack
Slack signs its requests using a secret unique to your app. With the help of signed secrets, your app can more confidently verify whether requests from Slack are authentic. The signing process is the cooler, younger sibling of verification tokens. Understanding HTTP requests from Slack Slack uses HTTP requests to notify your app that something has happened. If you're subscribed to the Events API,
Create and configure apps with manifests
Use the app manifest system to quickly create, configure, and reuse Slack app configurations. Manifests are YAML or JSON-formatted configurations bundles for Slack apps. With a manifest, you can use a UI or an API to create an app with a pre-defined configuration, or adjust the configuration of existing apps. You can share and reuse your manifests. Use this capability to create development clones

Sending messages using incoming webhooks
Incoming webhooks are a way to post messages from apps into Slack. Creating an incoming webhook gives you a unique URL to which you send a JSON payload with the message text and some options. You can use all the usual formatting and layout blocks with incoming webhooks to make the messages stand out.
