Using Google Pub/Sub

The Slack API has specific requirements for response times, which can be challenging if your app involves long-running processes. To overcome this limitation, you can leverage Google Pub/Sub, a messaging service that allows for secure communication between different Google Cloud services. By queuing up background jobs using Pub/Sub, you can handle time-consuming tasks without exceeding Slack's response time limitations.

Handling Incoming Messages

A common use case for Slack apps is to handle incoming messages and perform actions based on their content. For example, you might want to parse incoming messages for specific keywords or commands and trigger certain operations in response.
