The Best Slack Integrations and Apps in 2026

Slack is where most teams already spend their day, but a channel is only as useful as the tools feeding it. On its own it is a chat app; wired into your calendar, your tickets, your code, and your CRM, it becomes the place work actually happens. The Slack Marketplace lists more than 2,600 apps in 2026 — from two-way Salesforce and Zoom connectors to one-off incoming webhooks teams build themselves.

Here are the Slack integrations actually worth setting up, grouped by what they do — and then the way to connect Slack to anything with an API.

Video and meetings: Zoom, Google Meet, Microsoft Teams, Webex

Zoom — Start or join a meeting from any channel with /zoom, and drop the recording link back in automatically when the call ends.
Google Meet — Launch a Meet call straight from a Slack message and share the join link in the thread.
Microsoft Teams Calls — Bridge Teams calling into Slack so hybrid stacks can still reach each other.
Webex — Spin up Webex meetings and get join reminders without leaving the conversation.

Project management: Asana, Jira, Trello, Linear, ClickUp

Asana — Create tasks from Slack messages, and get notified in-channel when a task changes status or hits a due date.
Jira Cloud — File and update issues from Slack, with unfurled previews showing status and assignee inline.
Trello — Turn a message into a card and get board activity posted to the channel.
Linear — Create issues from Slack and sync status changes back for engineering teams.
ClickUp — Create and attach tasks, and receive comment and status updates in-channel.

Files and storage: Google Drive, Dropbox, Box, OneDrive

Google Drive — Share Drive files with proper permission prompts and get comment and access-request notifications in Slack.
Dropbox — Preview shared Dropbox files inline and post activity to a channel.
Box — Share Box content with in-Slack previews and permission controls.
OneDrive and SharePoint — Surface Microsoft-stored files and their updates for teams on the Microsoft stack.

Calendar: Google Calendar and Outlook

Google Calendar — Push event reminders into Slack, auto-set your status during meetings, and respond to invites without opening your calendar.
Outlook Calendar — Same reminders, status sync, and RSVP flow for Microsoft 365 teams.

Developer tools: GitHub, GitLab, PagerDuty, Datadog, Sentry

GitHub — Get PR and issue notifications, and open, close, or comment on them from Slack with rich unfurled previews.
GitLab — Post pipeline, merge-request, and issue activity to channels.
PagerDuty — Trigger, acknowledge, and resolve incidents from Slack so on-call responders stay in one place.
Datadog — Send alerts and graphs into channels and act on monitors inline.
Sentry — Route error alerts to the right team channel with links back to the stack trace.

Support and CRM: Zendesk, Intercom, Salesforce, HubSpot

Zendesk — Create and update tickets from Slack and get new-ticket alerts routed to the right team.
Intercom — Surface new conversations and reply to customers without leaving Slack.
Salesforce — As Slack’s parent, Salesforce offers deep two-way sync: pull up records, get deal alerts, and update opportunities from a channel.
HubSpot — Get deal and contact notifications and log activity back to the CRM from Slack.

Native no-code: Workflow Builder

Workflow Builder — Slack’s own point-and-click automation: trigger a workflow from an emoji reaction, a form, a scheduled time, or a new channel member, then post messages or collect responses. Great for simple internal flows, no code required.

No-code automation: Zapier and Make

Zapier — Connect Slack to thousands of apps with trigger-action “Zaps.” Good for basic field-mapping like “new form entry → post to channel.”
Make — Visual multi-step scenarios that route Slack messages to other tools. Both handle plumbing well but don’t reason over the content — they move fields, they don’t make judgment calls.

The AI way to connect Slack to anything: Carly

Zapier moves a field from A to B. It can’t read a thread, decide what matters, and take a different action depending on what was said. That’s the gap Carly fills. Carly is an AI executive assistant that connects to 200+ tools — Slack included — and lets you bring your own API key to connect to anything else with a REST API.

Acts on triggers 24/7 — runs in the cloud and responds to Slack messages, mentions, or schedules even when you’re offline.
Reasons over your data — reads a thread or ticket and decides what to do, instead of blindly copying one field to another.
Ties Slack to the rest of your stack — Gmail, Outlook, your calendar, your CRM, and more, in a single workflow.
Builds from plain English — describe the automation you want and Carly assembles the workflow for you.

Carly’s AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. Carly also integrates with Slack.

How to connect Slack to a tool with no native integration

In Slack, create an app at api.slack.com/apps, add the scopes you need (like chat:write or incoming-webhook), and copy the bot token or webhook URL it generates.
Paste that token into Carly on the integrations page — or connect Slack natively there in one click.
Describe the workflow in plain English (for example, “when a customer message lands in #support, summarize it and open a Zendesk ticket”) and Carly builds it.

Frequently Asked Questions

Does Slack have integrations?

Yes. The Slack Marketplace lists more than 2,600 apps in 2026, covering video, project management, storage, calendars, developer tools, support, and CRM — plus a native Workflow Builder and incoming webhooks for building your own.

What is the best Slack integration for automation?

For simple internal flows, Slack’s built-in Workflow Builder is the fastest start. For automations that need to read a message, reason over it, and act across other tools, an AI layer like Carly goes further than field-mapping tools like Zapier.

How do I connect Slack to an app that isn’t listed?

Create a Slack app to get a bot token or incoming webhook URL, then paste it into an automation platform like Carly and describe what you want to happen. Any tool with a REST API can be wired in this way.

How much does an AI automation for Slack cost?

Carly’s AI agents start at $35/month, with non-AI workflow steps running free and unlimited. Slack itself has a free tier, and paid Slack plans add unlimited app connections and message history.

See what people say

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.

Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.

On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
