These docs describe an outmoded approach to composing messages and interactive experiences. Learn how to more effectively communicate and help folks get work done by our new documentation and transitioning to "blocks". Simplify complex workflows and empower users to take decisive action by adding interactive buttons to your messages. Make your notifications, slash commands, and bot users more intu

Most Slack integrations (especially bot users and slash commands) require a server to respond to and initiate requests. Below you'll find the services most often used to host Slack integrations and apps. Amazon Web Services (AWS) A suite of on-demand cloud computing platforms, including Elastic Compute Cloud (EC2), a simple web service interface, and Lambda, a serverless compute service that rapid

Sign in with Slack helps users log into your service using their Slack profile. The Sign in with Slack flow will redirect users to the right Slack URL. Slack will send users back to your service, along with the information your service needs. The flow is based on the OpenID Connect standard, built on top of OAuth 2.0. The modern Sign in with Slack flow works with any package that successfully impl

Using legacy custom integrations is an outdated way for teams to integrate with Slack. Legacy custom integrations lack newer features and will be deprecated and possibly removed in the future. We do not recommend their use. We recommend using their replacement: Slack apps. Slack apps can be built just for your own workspace or distributed through the Slack Marketplace, and they can use the latest

Slash commands allow users to invoke your app by typing a string into the message composer box. By enabling slash commands, your app can be summoned by users from any conversation in Slack. Slash commands created by developers cannot, however, be invoked in message threads. A submitted slash command will cause a payload of data to be sent from Slack to the associated app. The app can then respond

This article describes an outdated approach to apps. Slack apps are installed with the V2 OAuth 2.0 flow. OAuth 2.0 is a protocol that lets your app request authorization to private details in a user's Slack account without getting their password. It's also the vehicle by which Slack apps are installed on a team. Your app asks for specific permission scopes and is rewarded with access tokens upon

This method allows you to create or upload an existing file. You must provide either a file or content parameter. The content of the file can either be posted using an enctype of multipart/form-data (with the file parameter named file), in the usual way that files are uploaded via the browser, or the content of the file can be sent as a POST var called content. The latter should be used for creati

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

Slack apps act independently of a user token. Build a bot user powered by only the specific permissions it needs. Check out Slack apps now. What are bots? A bot is a type of app designed to interact with users via conversation. You can enable conversations between users and apps in Slack by building these bots. Beginning March 31, 2025, we will discontinue support for legacy custom bots. For your

The Slack button is an efficient way to offer your service to teams using Slack. A Slack button app gives you incoming webhooks, slash commands and bot users wrapped in OAuth.

The legacy Real Time Messaging API is a WebSocket-based API that allows you to receive events from Slack in real time and send messages as users, including bot users. It's sometimes referred to as the "RTM API". It was once the basis for all Slack clients and once commonly used with bot users to create helper bots for your workspace. We recommend having events pushed to you instead, using the HTTP
