Connect Asana and Slack by installing the Asana for Slack app from Slack’s app directory, then authorizing your Asana account when the Asana bot prompts you. Once connected, type /asana in any channel to create or update tasks, turn messages into tasks from the three-dot menu, and link projects to channels for notifications.
That is the short version. The longer version matters, because the Asana Slack integration is one of those tools that looks trivial in a demo and then quietly breaks in ways that make people distrust it. I have set this up for teams that ran it for years and for teams that abandoned it after a week because a private project leaked into the wrong channel. Below is how to install it properly, the three procedures you will actually use, and the failure modes nobody warns you about.
What the Asana for Slack integration actually does
The integration does four useful things and stops there. It turns Slack messages into Asana tasks or comments. It makes pasted Asana links interactive, so you can reassign, complete, or reschedule a task without opening Asana. It runs slash commands (/asana) for creating and listing tasks. And it pushes notifications from a linked project into a channel.
Two AI features sit on top of that: task summaries (paste a task link, click Summarize task) and Smart chat, where you ask questions about your work from inside Slack. Both need extra plan conditions, covered below. What the integration does not do is act as a full field-by-field two-way sync. Treat it as a capture-and-notify bridge, not a mirror of Asana.
Before you start: plans and permissions
The app itself works on every Asana plan, including the free Personal plan, and on Slack’s free plan. The two things that trip people up are approval and Slack’s own limits. Many Slack workspaces require an admin to approve third-party apps before anyone can install them, so if you see a message that you are not authorized to install Asana, that is a Slack admin setting, not an Asana one. On Slack’s free plan, the app also counts toward the ten-app limit and the 90-day message history window, which quietly matters when you try to turn an older message into a task.
Smart chat needs a paid Asana plan and a paid Slack plan together. AI task summaries need Asana AI enabled for your organization. If either is missing, the buttons simply will not appear, which people often misread as a bug.
How to install the Asana for Slack app
- In Slack, open Apps in the left sidebar (or the Slack app directory) and search for Asana.
- Click Add (or Install) on the official Asana for Slack listing. If your workspace gates apps, this sends a request to your Slack admin instead of installing immediately.
- Open the direct message from the Asana bot and click Connect Asana account. You will be sent to Asana to sign in.
- Choose the correct Asana workspace or organization, then click Allow to let Asana and Slack exchange information.
- Back in Slack, type /asana help. If you get a menu of commands, the connection is live. If nothing happens, the app either is not approved or needs re-authorization.
One note from experience: if you migrated from the older Asana Slack app, slash commands and message actions stop working until each person re-authorizes. That is expected behavior during Asana’s migration window, not a failure. Have the team re-connect through the bot prompt.
How to create an Asana task from a Slack message
This is the feature that earns its keep, because it captures requests before they scroll away.
- Hover over the Slack message you want to capture and click the More actions three-dot icon.
- Choose Create a task to make a new task, or Add to task to attach the message to an existing one. You can also pick Add as task comment.
- In the dialog, set the task name, assignee, due date, and project. Always set the project here; skip it and the task lands in your My Tasks with no home.
- Submit. Asana adds a link back to the original Slack thread inside the task, so the context travels with the work.
To create a task without a source message, type /asana create and fill in the same fields. When you paste an existing Asana task link into any channel, it unfurls into an interactive card where anyone with access can mark it complete, like it, or change the assignee, due date, or project.
How to set up channel notifications for a project
- Open the Slack channel that should receive updates. Use a dedicated channel, not a busy general one.
- Type /asana and choose the option to link or connect a project to the channel.
- Select the Asana project you want the channel to track.
- Choose which notification types to send. You can limit it to events like task added, task completed, comments, or status updates rather than every change.
- Confirm. Matching activity from that project now posts into the channel.
For anything more conditional than that, skip channel notifications and build an Asana rule instead. Rules let you post to a specific channel or person only when a precise trigger fires, which keeps signal high and noise low.
Where the integration falls short
Notification noise is the first thing to go wrong. Linked-project notifications filter by event type, not by assignee or section, so a mid-sized project can bury a channel in updates. A single shared channel linked to three active projects becomes unreadable within a day.
The privacy behavior is the one to take seriously. Updates from private projects, portfolios, and goals can be delivered to a channel that includes people who are not members of those private items. Asana does not reconcile channel membership against project membership. Keep private work in private channels, and use /asana settings to stop private task and project descriptions from unfurling.
Private channels have their own trap: the Asana app cannot post in a private channel it has not been invited to. If you link a project but never run /invite @Asana in that channel, the setup looks correct on the Asana side while no messages ever arrive.
Finally, the connection is more fragile than people assume. SSO token expiry, an admin revoking app approval, a password reset, or the migration window can all silently sever slash commands and message actions. When that happens there is no error popup; the commands just stop responding until you re-authorize.
Troubleshooting common problems
- Slash commands do nothing: you likely need to re-authorize after a migration or token expiry. Type /asana and follow the re-auth prompt from the bot.
- Notifications stopped arriving: confirm the project is still linked, the Asana app is still a member of the channel, and your Slack admin has not revoked the app. For a deeper walkthrough, see why Asana notifications aren’t reaching Slack.
- Task links do not unfurl into cards: enable link previews in your Slack preferences; unfurling is what powers the interactive buttons.
- “You are not authorized to install Asana”: your Slack workspace requires admin approval for apps. Send the request to your admin.
- Too many notifications: trim the notification types on the linked project, or move that project to its own channel.

Frequently asked questions
Is the Asana Slack integration free?
Yes. The Asana for Slack app works on every Asana plan, including the free Personal plan, and on Slack’s free plan. Two features need paid tiers: Smart chat requires a paid Asana and paid Slack plan, and AI task summaries require Asana AI to be enabled for your organization.
Can I create a task in a specific project from Slack?
Yes. When you create a task from a message or run /asana create, the task dialog lets you pick a project and assignee before you submit. If you skip the project, the task lands in your My Tasks, where you can move it later. Set the project every time to avoid orphaned tasks.
Why does the Asana app post private project updates to my channel?
Asana sends linked-project updates to whichever channel you connected, and it does not cross-check channel membership against project membership. So people in the channel who aren’t project members can see activity. Keep private projects in private channels, and use /asana settings to stop private descriptions from unfurling.
Do notifications work in private Slack channels?
The Asana app can only post in a private channel if you invite it there first. Open the private channel, type /invite @Asana, then link the project. Without that step, the connection looks configured on the Asana side but no messages ever arrive, which is a common reason notifications appear broken.
Does the integration sync comments both ways?
Not by default. From Slack you can create tasks, comment, mark complete, and change the assignee, due date, or project through the task preview. Full two-way comment syncing between a task and a channel needs a Rule set up on the Asana side, which posts new comments to Slack and pulls replies back.
