Slack App Review


Slack brings team communication and collaboration into one place so you can get more work done, whether you belong to a large enterprise or a small business. Check off your to-do list and move your projects forward by bringing the right people, conversations, tools, and information you need together. Slack is available on any device, so you can find and access your team and your work, whether you’re at your desk or on the go.

Slack is a communication software platform for teams to chat, share documents, and have video conferences.

It was first released as a free beta in February 2014 and then became a paid service with a freemium version. The company is headquartered in San Francisco.

Slack has been described as a mix of IRC and Google Docs. Slack provides a variety of communication services such as channels (public and private), direct messaging (private), and chat (public and private). These communication channels can be for a team of people or a single person.

One of the main advantages of Slack is that it is effortless to set up and use. The software is available for Windows and Mac computers, Android and iOS phones and tablets, and a web browser. On the computer, it can be installed as a stand-alone app. A version of it is also available as a browser-based web app.

The user interface is user-friendly, so new users can sign up and start using it quickly.

Slack FAQ

Slack FAQ

  • How do I set up my developer environment?

    There’s no explicit sandbox or developer environment available to work against. Instead, you’ll need to use a workspace you’ve created or are a member of.

    It’s best to keep your integration or app’s ownership contained within the workspace that is responsible for it.

    Start by building a Slack app to contain all of your work — by default, it can only (& easily!) be installed on your own workspace. Follow the UI instructions to add features — most require that you provide a HTTP server Slack can reach.

    While developing for your own workspaces or if developing internal integrations, HTTPS will not be required for requests sent from Slack. This is for ease in getting started; we strongly recommend using HTTPS even for internal integrations.

  • How are incoming webhooks, slash commands, and bot users different?

    All three integration types allow you to post messages within a channel but differ in how those messages are triggered and how users interact with your app.

    You can use all of these integration types together in your Slack app.

    • Incoming webhooks – send messages to a channel at will by using a specific URL. Best used when the activity that would incite posting a message occurs in remote service.
      • Example: If you have an issue tracking system and want to post to a channel when a bug is created or resolved, use an incoming webhook invoked from your issue tracking system.
    • Slash commands – members execute slash commands from within Slack, resulting in us triggering your server to return them a message. The message can either be displayed only to the executing user, or to the channel from which it was triggered.
      • Example: Your slash command allows users to create and resolve bugs from the Slack command line with either action resulting in a message being displayed to that channel.
    • Bot users – Your service monitors channels and direct messages for certain conversational triggers, like the specific text in messages posted or emoji responses. As appropriate, your bot user posts messages or performs tasks inside or outside of Slack on a team’s behalf.
      • Example: Your bot monitors a channel’s messages for specific issue IDs and sends the channel a message containing details about them.
      • Example: Your bot tracks a team’s emoji reactions and sends a message at the end of the day to celebrate those most used.
  • Is Slack down?

    Of course, we want to Slack fully functional for users and developers at all times. Here are some tips in the unfortunate event you’re having trouble and need to determine exactly how broken Slack might be.

    When possible, we report on current status promptly through these channels:

    • Check for any service disruption advisories.
    • Follow @SlackStatus on Twitter for real-time updates on system health.

    Try these tips to further divine service health when these resources aren’t convincing:

    • Send a simple HTTP GET to the API method. An HTTP 200 application/json response of {"ok":true} indicates at least part of the Slack Web API is available.
    • Send a more complex, authenticated request to using a bot, user, or legacy token. Using this method exercises the authorization and API layer further than api.test and may grant you the serenity of greater confidence in Slack availability.
    • Do you use RTM? Slack does. Try using rtm.connect to generate a WebSocket URL using a token with the proper permissions, then open the socket using a tool like this simple browser-based WebSocket client for Google Chrome.

    • One of the most unreliable apps I’ve ever used.

    • This is my main work app and very happy with it because it helps my team and me to really organize and follow all projects. The only things is that when you take calls on the phone you can not see the screensharing and sometimes that is not good at all. Besides that, nice app for tech teams.

    • I use Slack on my desktop (browser) and the mobile app, and it’s very frustrating that notifications aren’t in sync anymore. My phone still shows notifications that I read hours ago in the browser.
