Slack URL to open a channel from browser

Question

This iTunes URL will open The Hitchhiker's Guide to the Galaxy in your iTunes:

itmss://itunes.apple.com/us/audiobook/hitchhikers-guide-to-galaxy/id315596797

This Spotify URL will open ALL by the Descendents in Spotify:

spotify:track:22feF2sbtGydtvx1OeLSih

Does Slack have a URL scheme to open a #channel in the Slack app from a link?

I want to put a link on my team's site that can link to the Slack #channel we use, for use by other people in the company.

Answer 1

The URI to open a specific channel in Slack app is:

slack://channel?id=<CHANNEL-ID>&team=<TEAM-ID>

You will probably need these resources of the Slack API to get IDs of your team and channel:

• GET https://slack.com/api/team.info
• GET https://slack.com/api/conversations.list?exclude_archived=1

Here's the full documentation from Slack

Very promising. I don't have the API token of my organization, but that's doing something from Firefox and Safari (not Chrome?). – Ozmo

You can get your team id and each channel's id from doing a View Source on the web version of Slack fyi. – Annam

This doesn't seem to work for me. slack:// opens the app but the channel/team are ignored. – Ihab

And more on getting your team and channel IDs here: https://mcmap.net/q/129507/-what-is-the-simplest-way-to-find-a-slack-team-id-and-a-channel-id – Obreption

This requires the user to be already signed in the specific workspace on the device that we are using the URI on. – Chaetopod

Answer 2

Referencing a channel within a conversation

To create a clickable reference to a channel in a Slack conversation, just type # followed by the channel name. For example: #general.

To grab a link to a channel through the Slack UI

To share the channel URL externally, you can grab its link by control-clicking (Mac) or right-clicking (Windows) on the channel name:

The link would look like this:

https://yourteam.slack.com/messages/C69S1L3SS

Note that this link doesn't change even if you change the name of the channel. So, it is better to use this link rather than the one based on channel's name.

To compose a URL for a channel based on channel name

https://yourteam.slack.com/channels/<channel_name>

Opening the above URL from a browser would launch the Slack client (if available) or open the slack channel on the browser itself.

To compose a URL for a direct message (DM) channel to a user

https://yourteam.slack.com/channels/<username>

I like /channels links: very convenient and straightforward. I checked that they also work for people DM channels: use yourteam.slack.com/channels/person to open @person DM. – Istic

It is possible to add some text query string to redirect with a message? – Herewith

Answer 3

Sure you can:

https://<organization>.slack.com/messages/<channel>/

for example: https://tikal.slack.com/messages/general/ (of course that for accessing it, you must be part of the team)

Maybe I should have been more specific, but I want to open the Slack app from a link. I've edited the question. – Ozmo

Are you sure that everyone installed the desktop app and that everyone has the same OS (Windows? Mac?) Also activating an application from within a browser is a security risk. – Acrophobia

The OS shouldn't matter if this is enabled, as the browser is launching the application. It's also not a security risk to do this, lots of apps have this capability. It's a link for people with the Slack app, so they'll only click it if they have Slack. – Ozmo

Slack app activation is different on different OS - you don't activate the Mac app with the same command as the Windows app – Acrophobia

The OS will prompt you if it doesn't recognize the custom protocol handler, but if Slack has this enabled, then it wouldn't be a problem. – Ozmo

It's a pretty common thing called Deep Links, or URI schemes, iTunes has had it for years. – Englebert

Just as a side-note, these links only allow access to those that are already a member of the relevant organisation. For example, in the demo link given above, you need to have the rights to access Tikal.slack.com. Otherwise it will tell you that your account details are incorrect. – Johnsten

Answer 4

This link opens the channel in the browser

https://<org-name>.slack.com/channels/<channel-name>

This link opens up the slack channel in the App

https://<org-name>.slack.com/archives/<channel-name>

Answer 5

You can use

slack://

in order to open the Slack desktop application. For example, on mac, I've run:

open slack://

from the terminal and it opens the Mac desktop Slack application. Still, I didn't figure out the URL that should be used for opening a certain team, channel or message.

Answer 6

When I tried yorammi's solution I was taken to Slack, but not the channel I specified.

I had better luck with:

https://<organization>.slack.com/messages/#<channel>/

and

https://<organization>.slack.com/messages/<channel>/details/

Although, they were both still displayed in a browser window and not the app.

Gordy

Right, I'm aware of the URL for slack messages. My only goal is to have it open in the app. – Ozmo

Correction to the first link above (do not include the hash): https://<organization>.slack.com/messages/<channel>/ – Hydrograph

Answer 7

What you need is this:

slack://channel?team=your workspace id&id=channel id

This will tell the browser to open the Slack App and take you to the given channel in the given workspace.

The problem I see is that Slack does not give you an easy way to copy this URL. Instead, it gives you the option to copy the https://your workspace name.slack.com/archives/channel id of a channel, which will also work, if your browser supports it, but it will leave behind an ugly empty new browser tab opened.
