How to Create a Unified.to Connection to HighLevel

March 19, 2026

This guide explains how to connect an existing HighLevel account to Unified.to. It assumes:

  • You already have a Unified.to account
  • You already have a HighLevel account
  • You have access to a HighLevel Developer (Agency) account

Overview

To create a connection between Unified.to and HighLevel, you will:

  1. Create or configure a HighLevel OAuth app
  2. Collect required credentials (Client ID, Client Secret, etc.)
  3. Use Unified.to to create a connection
  4. Authorize the connection via OAuth

Step 1: Create a HighLevel OAuth App

  1. Log in to your HighLevel Developer (Agency) account link
  2. Navigate to the App Dashboard.

Keep these secure. You will need them in Unified.to.

Step 3: Create Connection in Unified.to

  1. Log in to your Unified.to dashboard
  2. Navigate to Integrations.
  3. Select HighLevel as the integration
  4. Enter the following details:
    • Client ID (from HighLevel)
    • Client Secret (from HighLevel)
    • Version ID (from HighLevel)
  5. Click Activate
  6. Go to Embedded Components.
  7. Click HighLevel.

Step 4: Authorize the Connection

  1. You will be redirected to HighLevel
  2. Log in (if not already logged in)
  3. Select the account/location you want to connect
  4. Approve the requested permissions

Once approved, you will be redirected back to Unified.to

Common Issues & Troubleshooting

1. Invalid Redirect URI

  • Ensure the redirect URL in HighLevel exactly matches the one used by Unified.to

2. Unauthorized / 401 Errors

  • Double-check Client ID and Client Secret
  • Ensure the OAuth app is active

3. Missing Data

  • Ensure correct scopes are selected in HighLevel
  • Some data may depend on the selected location/account

Notes

  • HighLevel uses location-based access. Make sure you select the correct location during authorization
  • You can create multiple connections for different locations if needed
