Identify data source type
If you're an existing Glean and Slack user, you may have one or more of the following Slack data sources:
- Central App
- Custom App
- Slack Enterprise Grid (Discovery API)
To find out which data source you are using, do the following:
- In Glean, go to Admin console → Data sources.
- Find your Slack data source and open the data source details page.
- Select the Setup tab.
- Review the fields under step 1 and select the data source type that matches your setup.
See the options below:
- Central App
- Custom App
- Slack Enterprise Grid (Discovery API)
Central App
If you see the following fields, you are using a Central App:
- Slack domain
- Slack ID

- Client ID
- Client secret
- Signing secret

Slack Enterprise Grid (Discovery API)
If you see the following fields, you are using a Slack Enterprise Grid (Discovery API):
- Slack Enterprise domain (for example,
yourdomain.enterprise.slack.com) - Bot User OAuth Token
- Bot Signing Secret
- App-Level Token

Enterprise customers without a custom Slack app will still see all of the fields above. The custom app fields (App-Level Token, Client ID, Client secret, Signing secret) may be blank. If those fields are empty in your existing connector configuration, they must be upgraded manually. Contact Glean Support to coordinate this migration.
