Overview
Build with the Slack Web API
Make your first Slack API call in under 5 minutes. Post messages, create bots, automate workflows, and ship integrations that live inside the place teams already work.
The Slack Web API is the fastest way to bring your product into a Slack workspace — send messages, react to events, build slash commands, automate routine work, and surface your data exactly where teams collaborate. This portal gives you everything you need to go from zero to a working integration.
Get Started in Seconds
Get API Credentials
Create a Slack App, pick your scopes, and grab the bot token you need to authenticate every call.
Make Your First API Call
Follow the 5-minute quickstart: install an SDK, post a message, and verify the response.
View SDKs
Production-ready client libraries for TypeScript, Python, Java, C#, PHP, Ruby, and Go.
Open API Reference
Browse every endpoint, test calls live in your browser, and copy ready-to-paste code samples.
Build for Slack
Whether you're shipping a focused bot, automating a multi-step process, or pushing alerts from another system, the Slack API gives you the primitives.
Workflows
Automate routine work with custom workflow steps, triggers, and connector functions that fit into Workflow Builder.
Bots
Listen for events, respond to slash commands, and hold real conversations with users in channels and DMs.
Integrations
Push alerts via incoming webhooks, sync data with external systems, and distribute your app on the Slack Marketplace.
Your Learning Path
A logical progression from "what is this?" to shipping in production.
1. Getting Started
Manuals. Set up credentials, install an SDK, and make your first call.
2. Build for Slack
Educational. Learn the platform — workflows, bots, integrations, and the patterns Slack apps share.
3. API Recipes
Development resources. Step-by-step recipes for the most common implementation flows.
4. API Reference
