Authentication for Slack

Prerequisites

Depending on the authentication type you select, you need one of the following credentials:

• OAuth 2.0 Authorization code: User scopes, Bot scopes, and your Slack credentials.
• Bring your own OAuth 2.0 app: Client ID, Client secret, User scopes, Bot scopes.

For creating a private OAuth2 app, follow the steps mentioned in the Slack documentation.

To be able to create a connection, you need to:

• be a member or a guest of a Slack workspace

Add the connection for Slack

To create a connection to your Slack instance, you need to perform the following steps:

1. Select Integration Service from Automation Cloud.

2. From the Connectors list, select Slack. You can also use the search bar to narrow down the connector.

3. Select the Connect to Slack button.
4. You can choose between two authentication types: OAuth 2.0 Authorization code or Bring your own OAuth 2.0 app.
   1. If you select the Bring your own OAuth 2.0 app method, enter the required credentials and select Connect.
   2. If you select the default OAuth 2.0 Authorization code method, follow the steps below.
5. Review or change the Bot scopes and/or the User scopes as per your requirement/use-case. This is an optional step, as the default scopes can be used as-is for connection creation

6. Select Connect.

7. You are now redirected to Slack sign in page. Enter your workspace URL and select Continue.
   

   

   
   
8. If you're a member of the workspace, select Sign in with SSO. If you're a guest, select I have a guest account and you are prompted to enter your email address and password. For this example, we are choosing to sign in with SSO.
   
   
   
   

9. Select Allow. With access to your Slack account, UiPath can do the following:

   • View content and info about you
   • View content and info about channels and conversations
   • View content and info about your workspace
   • Perform actions as you
   • Perform actions in channels and conversations

   • Perform actions in your workspace

     
     

     

     
     
10. Your connection has been added.
