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

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.

Solution 1:

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)

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:
