How to get token

;; I'm using use-package and el-get and evil

(el-get-bundle slack)
(use-package slack
  :commands (slack-start)
  :init
  (setq slack-buffer-emojify t) ;; if you want to enable emoji, default nil
  (setq slack-prefer-current-team t)
  :config
  (slack-register-team
   :name "emacs-slack"
   :default t
   :client-id "aaaaaaaaaaa.00000000000"
   :client-secret "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb"
   :token "aaaa-sssssssssss-88888888888-hhhhhhhhhhh-jjjjjjjjjj"
   :subscribed-channels '(test-rename rrrrr))

  (slack-register-team

   :client-id "3333333333.77777777777"

How to get token

1. Get client-id and client-secret

1. Go to "https://api.slack.com/apps".
2. Click "Create New App".
3. Fill "App Name" and "Development Slack Team" and click "Create App".
4. "Client ID" and "Client Secret" are listed in the "App Credentials" section.

2. Configure Redirect URL

1. Click "Permissions" in the "Add features and functionality" of "Building Apps for Slack" section.
2. Fill in the "Redirect URLs" section (slack-emacs defaults to: "http://localhost:8080").
3. click "Save URLs".

3. Get token

1. Call slack-register-team with above "Client ID" and "Client Secret" (ignore the "Token" prompt [i.e., just hit enter.]).
2. Emacs' prompt will display: "Enter the code your browser displayed: ".
3. Code appears in the browser's address bar like "http://localhost:8080?code=181818181818.1819919191&state=", enter this code in the previous Emacs' prompt.
4. Once you activate emacs-slack, token appears in the URL like: "https://api.slack.com/apps/{APPID}/oauth".
5. Save your token and pass it to the slack-register-team function along with the "Client ID" and "Client Secret".

Note

emacs-slack use websocket to communicate with Slack, and need request to rtm.start method (you can also test your settings in that page's "Tester" tab to make sure things have been configured correctly).
this request needs "client" scope when authorize and Slack does not yet have "client" scope in new OAuth scope.
make sure slack-oauth2-auth requesting with "client" scope and prevent token migration.
