Slack integrations are great for automating repetitive tasks and ensuring you don’t forget something important. They can also be used to connect multiple tools, integrate data from various sources, and create custom workflows. Slack integrations can be used for everything from customer support to marketing campaigns, and you find them for almost any type of business.

Slack integrations can help businesses increase collaboration and communication by allowing team members to talk directly to each other in real-time. This can help improve customer service by providing faster response times. It also allows teams to share information more easily between departments, which can improve overall efficiency.

How Do Slack Integrations Work?

In addition to its basic features, Slack has integrations, including Slack apps, bots, and tools, that allow you to connect third-party apps and services to Slack. With integrations, you can easily communicate with each other and share information across different platforms. For example, you can use them to automate things like sending reminders, setting up meetings, and even defining real-world bonuses and automated rewards.

How to Add Integrations to Slack

By default, any member of a workspace can add apps to Slack, but owners and admins can restrict this privilege. Once an app is added to your workspace, you and the other workspace members must connect your respective accounts as part of the installation process before you start using it.

Slack has its own app directory, but you can also integrate other apps offered by third-party developers. Keep in mind that the free version of Slack only lets you add up to ten apps and tools to your workspaces. To get unlimited access to integrations and other features, you need to sign up for one of Slack’s paid subscription plans.

To install an app from the Slack app directory, follow these steps:

  1. Navigate to your workspace in Slack. Click Browse Apps (vertical three-dots symbol) on the left side, then select Apps.
  2. You can search for an app on this page if you already know what you want to install. To see all available apps, click on App Directory in the top right corner.
  3. On the app page, click Add to Slack. You’ll be prompted for access permissions. Click Allow. This will bring you to the account sign-in page.
  4. After signing in, the app will be connected to your workspace and appear on the left side. You’ll also get a message telling you what app alerts and commands are available.

To connect an external integration that isn’t built into Slack, you can visit the app page, sign up with your Slack account, and give access permissions to connect it to your workspace.
