Re-authenticating

Sometimes you may need to re-establish the connection between Kleer and HubSpot.

When to Re-authenticate

You may need to reconnect if:

• The settings page shows a disconnected status
• Syncs are failing with authentication errors
• You've changed your Kleer API key
• You've changed HubSpot portal permissions

Updating Your Kleer API Key

1. Generate a new API key in your Kleer account settings
2. Open the Kleer for HubSpot settings page in HubSpot
3. Update the API key in the credentials section
4. Save — the connection status should update immediately

Reconnecting HubSpot

If the HubSpot OAuth connection has expired or broken:

1. Go to Settings > Integrations > Connected Apps in HubSpot
2. Find Kleer for HubSpot
3. Disconnect and reinstall the app to re-authorize

After Re-authenticating

The integration resumes syncing on its normal schedule automatically. No data is lost during the disconnection — the next sync picks up any changes that occurred while the connection was down.

Preventing Issues

• Don't revoke API keys that are in active use — generate a new one first, update the integration, then revoke the old one
• Ensure the HubSpot user who authorized the integration retains the necessary permissions
