<a name="slack-step-4"></a>

In this section, use the Slack API console to complete integration with the Slack application.

1. Sign in to the Slack API console at [https://api.slack.com](https://api.slack.com). Choose the app that you created in [Step 2: Create a Slack application](slack-step-2.md).

1. Update the **OAuth & Permissions** feature as follows:

   1. In the left menu, choose **OAuth & Permissions**.

   1. In the **Redirect URLs** section, add the OAuth endpoint that Amazon Lex provided in the preceding step. Choose **Add**, and then choose **Save URLs**.

   1. In the **Bot Token Scopes** section, add two permissions with the **Add an OAuth Scope** button. Filter the list with the following text:
      + **chat:write**
      + **team:read**

1. Update the **Interactivity & Shortcuts** feature by updating the **Request URL** value to the endpoint that Amazon Lex provided in the preceding step. Enter the endpoint that you saved in step 3, and then choose **Save Changes**.

1. Subscribe to the **Event Subscriptions** feature as follows:
   + Enable events by choosing the **On** option.
   + Set the **Request URL** value to the endpoint that Amazon Lex provided in the preceding step. 
   + In the **Subscribe to Bot Events** section, select **Add Bot User Event** and add the **message.im** bot event to enable direct messaging between the end user and the Slack bot.
   + Save the changes.

1. Enable sending messages from the messages tab as follows:
   + From the left menu, choose **App Home**.
   + In the **Show Tabs** section, choose **Allow users to send Slash commands and messages from the messages tab.**

1. Choose **Manage Distribution** under **Settings**. Choose **Add to Slack** to install the application. If you are authenticated to multiple workspaces, first choose the correct workspace in the upper right-hand corner from the drop-down list. Next, select **Allow** to authorize the bot to respond to messages. 
**Note**  
If you make any changes to your Slack application settings later, you must redo this substep.
