How do I find my HighLevel API v2 Access Token?

You can obtain an API v2 Access Token by creating an application in the **HighLevel Developer Portal** (marketplace.gohighlevel.com) and performing the OAuth 2.0 handshake. Ensure you grant the necessary scopes for contacts and opportunities.

Can I check calendar availability in real-time?

Yes! Use the `get_calendar_free_slots` tool by providing the calendar ID and a date range. The agent will return all available appointment slots for that period.

Does the integration support creating new opportunities?

Yes, you can use the `create_opportunity` tool. You must provide a JSON string containing the pipeline ID, stage ID, and contact details to add a new deal to your sales funnel.

Is the integration secure for CRM data?

Absolutely. The integration uses official HighLevel API v2 OAuth 2.0 Bearer tokens over HTTPS. Your credentials and customer data are encrypted and stored securely within the Vinkius Cloud infrastructure.
