To jump straight into developing your own Slack app, follow our Quickstart. You can get started right now. Hello there, fellow developer! 👋 Welcome to the Slack API documentation, the place where ideas turn into interactive apps, workflows get automated, and Slack becomes the platform that powers your workday. Our documentation on APIs, SDKs, and tools can assist you in creating apps that make wo

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

Socket Mode allows your app to use the Events API and interactive features—without exposing a public HTTP Request URL. Instead of sending payloads to a public endpoint, Slack will use a WebSocket URL to communicate with your app. WebSockets use a bidirectional stateful protocol with low latency to communicate between two parties—in this case, Slack and your app. Unlike a public HTTP endpoint, the

When users post messages in Slack containing links, we attach previews, adding context and continuity to conversations. Classic link unfurling is the default treatment for links posted in Slack. When a link is spotted, Slack crawls it and provides a preview. Slack app unfurling is a more customizable experience initiated when Slack recognizes a link associated with your app and then sends your Sla

Tools built by SlackThese libraries, tools, open specifications, and assets are built by Slack.

We don't recommend using or creating Steps from Apps for the legacy workflow builder. Instead, build functions and triggers for modern workflows using our new automation platform. This tutorial is a great place to start. Alternatively, build a Bolt app that you host and customize it with custom steps for Bolt apps. Learn more about the deprecation or read our Survival Guide & FAQ. Steps from apps

Apps that only listen can be useful, but there's so much more utility to explore by transforming a monologue into a conversation. Give your app the gift of dialogue by setting it up to send Slack messages. This guide will help you learn a basic way to accomplish this and show you the paths you can take to make things complex and interactive. Sending messages​ If you don't have a Slack app yet, her

We released the Conversations API in September 2017 as a one-size-fits-all replacement for a variety of APIs used to read and write information about channels, private channels, direct messages, and multi-party direct messages. Today we are announcing the deprecation of the methods that preceded the Conversations API (channels.*, groups.*, im.*, & mpim.*). On November 25th, 2020 February 24th, 202

These are developer-focused instructions that cover posting messages to Slack via APIs. For user instructions on message formatting in your Slack client, refer to this Help Center article. App surfaces such as messages, modals, or Home tabs can contain all types of textual treasures. The text itself can be formatted and placed inside blocks to create rich message layouts.

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. If you're looking for the Help Center article on using webhooks with Workflow Builder, head over h

This autumn, Slack will make what-you-see-is-what-you-get (WYSIWYG) editing available to users. Once we release WYSIWYG editing, the text field found in message objects your app encounters will become an approximation of a user's more richly formatted message. To capture a message's full nuance and vibrancy, your app may look to the new blocks attribute included with such messages. What's changing

Slack apps are installed with a v2 OAuth 2.0 flow. We're sorry about all the "2s": OAuth 2.0 refers to the 2.0 version of the OAuth spec, and this is our second version of OAuth 2.0. For the rest of this guide, we'll just refer to it as "OAuth". For posterity, this OAuth flow works the same as the OAuth flow for legacy Slack apps. Only a few details have changed; URL and method names have gained a

The Slack developer docs are moving! We've been working hard at building out a new docs experience at docs.slack.dev — now in beta! You can start using the new docs today, but we'll keep the content on both sites up to date during the transition. 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 S

Slack で最もよく使われる 3 つの API は、あらゆる種類のアプリを開発するのに役立ちます。それぞれの API には、アプリの用途に応じてメリットがあります。例えば、イベントの通知が必要なアプリ、Slack チャンネルから情報を引き出すアプリ、送られてくるすべてのイベントをチーム内にストリーミングするアプリ、といった様々な用途です。 この記事では、Slack の Web API、Events API、RTM API について説明し、それぞれの一般的な使用例や、使い始めるためのヒントを紹介します。また、次の簡単なフローチャートを使

Slack platform features and APIs rely on rate limits to help provide a predictably pleasant experience for users. The details of how and when rate limiting works differs between features. This article gives an overview of the rate limits you're likely to encounter for Slack platform features, and then notes how the limits apply to each feature. Overview Broadly, you'll encounter limits like these,

In early 2019 we introduced a new way of composing messages, by using blocks to create rich and interactive layouts. Slack apps designed and built before then may have used features such as attachments which are now considered outmoded. These older features will continue to work, but apps using them will miss out on the new layout and interactivity features blocks provide. This guide is intended f

Blocks are visual components that can be stacked and arranged to create app layouts. Read our guide to learn how you can construct stacks of blocks and add them to your app's surfaces. Use special components to inject an app with interactivity. Read our overview to get a quick taster of the interactive components available, and pointers on how to integrate interactivity into your app. Shuffle and

In the following guide, you'll create a basic Slack app that can send messages using webhooks. 1. Creating an app​ Create a Slack app via the apps page by selecting the following button: Create an app Select From scratch. Enter your App Name. For this example, enter "Grocery Reminders". Select the Workspace where you'll be developing your app. You'll be able to distribute your app to other workspa

Bolt is the swiftest way to start building on the Slack Platform. Before you proceed with this tutorial, follow our Getting Started with Bolt for JavaScript, Python, and Java guides to get setup and ready to build. Your Slack app can publish text messages to public channels or private conversations just as users can. These messages can be used as notifications for your app. Apps can also include s

These docs describe an outmoded approach to collecting input. Learn how to collect more customized data and display dynamic information with our new documentation and our guide on upgrading dialogs to modals. Dialogs are designed to help you gather multi-part input from end-users in a structured way; think, for example, of a helpdesk ticket that contains a freeform description of an issue, but als

Slack is phasing out the @username artifact in favor of the more expressive and flexible concept of display names. Handles, aliases, call-signs, and usernames — in chat, they all represent the same concept: a way for an individual or entity to indicate a preferred identification noun, in whichever way is appropriate to the apparatus at work. Users will be even better equipped to present their pref
