# Create a Slack Application

To index content from Slack, you must create a Slack OAuth application to represent the connector.

To create a Slack OAuth application to represent the connector

1. Go to https://api.slack.com/apps.

2. Click Create New App.

   Make a note of the client ID and client secret. You will need this information to run the OAuth configuration tool that is supplied with the connector.

3. Click OAuth & Permissions.

4. Add a redirect URL.

   - To use the NiFi Ingest connector, the redirect URL must match the URL shown in the advanced configuration dialog of the NiFi processor.
   - To use the standard connector, the redirect URL must match the value of the `RedirectUrl` parameter in the OAuth tool configuration file, `oauth_tool.cfg`. The default value is `https://localhost:7878/oauth`.

5. Add the following User Token Scopes:

   Name | Justification
   --- | ---
   identify |
   channels:history | Process Channels
   channels:read | Process Channels
   groups:history | Process Groups
   groups:read | Process Groups
   im:history | Process IM
   im:read | Process IM
   mpim:history | Process MPIM
   mpim:read | Process MPIM
   files:read | Process Files
   emoji:read | Process Messages
   users:read | Mapped Security
   users:read.email | Mapped Security

6. Configure the connector to authenticate using OAuth, by following the steps in Configure OAuth Authentication.
