What is the simplest way to find a slack team ID and a channel ID?
As of July 2019, it seems like the team id and the channel id is already being shown via the web.
As you can see in the screenshot, the 2nd to the last node is the team id (prefixed with "T") and the last node is the channel id (prefixed with "C"). All you have to do is open slack via the web, go to the specific channel, and you can see the url change to something close to the screenshot above.
Here is the easiest way to manually find the slack IDs
1. Any channel ID
Open the slack webpage (http://yourteam.slack.com) and then simply open the channel. The channel ID is displayed in the browser URL:

To find a user ID you need to open your browser dev-tools console and inspect the user-link in the sidebar. The user ID can be found in the HTML attribute "data-member-id":
Or in slack: (1) Click on the users name and choose (2) "Show Profile". Then open the "..." menu and you see the option (3) "Copy Member-ID ..." - to get your own user ID via the UI, you have to click the Team-Logo in top-left corner and then choose "Profile & Account" (this is not included in the screenshot)
3. Team ID
Simply open the dev-tools of your browser, switch to the "Console" tab and enter the text boot_data.team_id into the console. This will display your team ID:
