Access token

Step 1. Create a Slack app

1. In your web browser, sign in to your Slack account.
2. In the web browser, open the Your Apps page.
3. If you don't have an app, create one to generate the access token.
   1. Click Create an App and choose the configuration for your app’s scopes and settings.
   2. Enter a name to identify your app, and select a workspace from the list.
   3. Click Create App.
4. If you already have an app, from the Your Apps page, click the app that you want to generate the access token.

Step 2. Define the app's Redirect URL

1. From the Features menu, click OAuth & Permissions.
2. In the Redirect URLs section, click Add New Redirect URL.
3. Enter the URL https://www.google.com, click Add, and then click Save URLs.

Step 3. Get the client ID and client secret

1. From the Settings menu, click Basic information.
2. In the App Credentials section, copy and save the values for Client ID and Client Secret.

Step 4. Authorize the app and get the authorization code

1. Paste the following link in your browser's address bar. Replace <client_id> with the client ID from the step 3:

   https://slack.com/oauth/authorize?response_type=code&state=123456789&client_id=<client_id>&redirect_uri=https://www.google.com&access_type=offline&scope=identify,channels:read,users:read,users:read.email,chat:write:bot,im:read,mpim:read,files:write:user,files:read,groups:read,usergroups:read,chat:write:user,im:write,mpim:write,search:read
   

2. If you see a page to authorize the app, click Allow.

3. From the URL in the address bar, copy the value from the code query. For example, https://www.google.com/?code=<Code>&state=123456789.

Step 5. Get the access token

1. From the following cURL command, replace the values from <code>, <client_ID>, and <client_secret> with your own values obtained in the previous steps.

   curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d "grant_type=authorization_code&code=<code>&redirect_uri=https://www.google.com&client_id=<client_id>&client_secret=<client_secret>" https://slack.com/api/oauth.access
   

2. Run the cURL command.

3. In the response, get the value from the access_token key, for example:

   {
     "ok": true,
     "access_token": "xoxp-6982842894404-...-7116482670706-a18522f88...2dc66f482df133c",

     "user_id": "X000XXXX0X0",
     "team_id": "X000XXXX0X0",
     "enterprise_id": null,
     "team_name": "Example"
   }
