Hub Connections

Hub connections are database credentials managed centrally and shared with users through groups. Users can execute workflows using these connections without seeing the credentials.

Client vs Hub Connections

Creating Connections

From Admin > Connections:

1. Click Create Connection
2. Enter connection details (name, type, host, port, database, username, password)
3. Click Test Connection to verify
4. Click Save

Credentials are encrypted before storage. The encryption key is stored separately in CONNECTION_ENCRYPTION_KEY environment variable.

Assigning to Grant Groups

A connection is not accessible to users until assigned to a grant group that is linked to a user group:

1. Go to Admin > Grant Groups
2. Create or select a grant group
3. In the Connections section, click Add Connection
4. Select the connection to add
5. Go to Admin > User Groups, select a user group
6. Go to the Grant Groups tab and assign the grant group

Users in that user group can now use the connection in workflows.

What Users See

Users see:

• Connection name
• Connection type
• Health status

Users do not see:

• Host, port, database
• Username, password

This is intentional - users can use connections without knowing where they point.
