Using API key

To configure this credential, you'll need:

Using OAuth2

To configure this credential, you'll need:

• A Client ID
• A Client Secret

To generate both, create an app in My Apps > Create App. Use these settings:

1. Set Distribution Type to Sub-Account.

2. Add these Scopes:

   • locations.readonly
   • contacts.readonly
   • contacts.write
   • opportunities.readonly
   • opportunities.write
   • users.readonly

3. Copy the OAuth Redirect URL from n8n and add it as a Redirect URL in your HighLevel app.

4. Copy the Client ID and Client Secret from HighLevel and add them to your n8n credential.

5. Add the same scopes added above to your n8n credential in a space-separated list. For example:

   locations.readonly contacts.readonly contacts.write opportunities.readonly opportunities.write users.readonly
