Team ID

The easiest way to get your team ID is to use the Slack API method auth.test with your access token.

Channel ID

Depends on if you want a public or private channel you can call the respective Slack API method to get a list of all channels incl. their IDs.

• Public channel: channels.list
• Private channel: groups.list

Note that you can only see private channels in which the user/bot that belongs to your access token has been invited into.

Accesss Token

To get the access token you can either request a "test token" on the Slack API page under "Test Token" (only recommended for testing purposes by Slack). Or you can create a Slack app and install that app for your Slack team using Oath which will also generate an app specific access token.
