1. What Is a Slack App?

A Slack app is a customized application that integrates seamlessly with the Slack platform and external applications to deliver organization-specific functionality and enhance workflows. These apps are designed to make your Slack workspace more efficient and tailored to your unique needs.

Slack apps offer a wide range of capabilities by leveraging the platform’s comprehensive access. This allows for the creation of enhanced and powerful experiences within Slack. Each Slack app is equipped with a variety of tools, including a range of APIs that provide access to read, write, and update all types of data in Slack.

Some features of Slack apps mirror what users can already do in Slack clients:

Sending messages to conversations using Web APIs and webhooks.
Creating, archiving, and managing conversations using conversation-specific Web APIs.
Receiving notifications about mentions, app home opens, and other activities via Events APIs.

However, Slack apps can also perform actions beyond the capabilities of human users:

Creating and updating a Home tab to provide users with a persistent space to interact and stay informed.
Empowering users to invoke interaction at any time with shortcuts.
Opening modals to collect information and provide a space for displaying dynamic details.
Publishing interactive components in messages, modals, and Home tabs to enable action and reaction.
Automating the management of users, apps, and workspaces using various enterprise-focused APIs.

2. What Are the Key Components of Slack App Surfaces?

Slack apps offer welcoming spaces through various app surfaces where apps can express themselves and interact with users. A surface is any area where an app can interact with users.

These surfaces are composed using Block Kit, a collection of visual components designed by Slack. These visual components have a consistent look and feel across every client and for every user.

2.1. What is App Home in Slack?

An App Home is a private, one-to-one space in Slack shared between the user and the app. Users can access the App Home from a workspace’s conversation list or by clicking on the app’s name in messages.

Within an App Home, there are several tabs. While some tabs like About and Messages are fixed, Home tabs can be fully customized by apps. The Home tab can be enriched with intricate layouts and deep interactivity.

2.2. What Are Slack Modals?

Modals are popups ideal for requesting and collecting data from users, or for temporarily displaying dynamic, interactive information. They provide a focused and streamlined way to gather input or present details.

2.3. What Role Do Messages Play in Slack App Surfaces?

Messages are dynamic yet transient spaces that allow users to complete workflows within their Slack conversations, forming a conversational interface of potentially limitless complexity. They facilitate real-time interaction and task completion.

Apps can utilize a combination of surfaces. Just because an action starts in a channel doesn’t mean that other members need to see the entire process or even the final result. Shifting tasks to a modal can help collect information quietly, make decisions privately, and finalize workflows efficiently.

3. What Are the Entry Points to Interactivity in Slack Apps?

Slack apps use interactive features to achieve two-way communication between apps and users. The interactive flow involves two steps:

Something happens that invokes the interaction.
The app responds to the interaction.

There are multiple ways to invoke the interaction, and apps have multiple ways to respond.

Your app can be invoked without any direct user input due to:

Scheduled interactions.
Interactions initiated by external services.
Interactions initiated by the Events API.

Users can invoke apps by using one of the following entry points:

3.1. What Are Slash Commands?

Slash commands are custom commands that users can type into the message bar to trigger specific actions within the app. They are ideal for quick, frequently used functions.

3.2. How Do Message Buttons Work in Slack Apps?

Message buttons allow users to take immediate action on a message, such as approving a request or completing a task, directly within the conversation.

3.3. What Are Slack Shortcuts?

Shortcuts are global actions that users can access from anywhere in Slack, providing quick access to key app features regardless of the current context.

When planning your Slack app, consider which entry point is most appropriate for each function.

For example, if your audience is less familiar with interactivity, slash commands might be difficult for them to use.

Slack users have varying levels of technical ability. Some may have poor internet connections, use Slack only on mobile, or may have never used a Slack app before. It’s crucial to consider your audience when designing your app to ensure a great experience for everyone.

In many cases, using all of the entry points may be the best approach. Your app can accomplish many different tasks, each best suited to a different entry point.

4. What APIs Are Essential for Developing Slack Apps?

The Slack platform is composed of several APIs that enable you to build apps of all shapes and sizes. These APIs generally work together, but there’s also some overlap that can sometimes be confusing. This section will help you identify the right API for your project.

4.1. What Is the Events API?

The Events API allows you to select the events you’re interested in receiving, and Slack sends them to an endpoint you specify via HTTP.

If you don’t want to expose a public, static HTTP endpoint to communicate with Slack, Socket Mode can be used.

4.2. What Is the Web API?

If the Events API is how Slack pings your app, the Web API is how your app responds to Slack. This often involves taking action on a Slack workspace, such as composing a message or creating a new channel. It can also be used to request information directly, such as a list of all the people in a workspace.

4.3. What Is the Conversations API?

The Conversations API is a subset of the Web API that includes functions specifically for managing channel-like objects in a Slack workspace, such as public and private channels, shared channels, external shared channels, DMs, and multiparty DMs.

While these channel-like objects behave similarly (e.g., you can list the users in them), each conversation has unique attributes, such as its privacy level or whether it’s shared across workspaces.

4.4. How Does Socket Mode Enhance Slack App Development?

Socket Mode allows you to use the Events API and interactive features of the platform without exposing a static HTTP endpoint to receive payloads. Instead, you use the WebSocket Protocol and generate a URL at runtime.

5. What Tools and SDKs Can Streamline Slack App Development?

A variety of SDKs, frameworks, and construction tools can streamline the process of building a Slack app.

5.1. How Do Bolt SDKs Simplify Slack App Development?

Bolt is a framework that allows you to build Slack apps quickly. It is available in JavaScript, Python, and Java.

Bolt handles much of the foundational setup, allowing you to focus on your app’s functionality. Out of the box, Bolt includes:

A basic web server to run your app on.
