Automate Outbound Voice Calls from GoHighLevel Opportunities with VAPI

This n8n workflow automates the process of initiating outbound voice calls through VAPI (Voice API) whenever a new opportunity is created or updated in GoHighLevel. It's designed to streamline communication, allowing businesses to immediately engage with new leads or follow up on existing opportunities without manual intervention.

What it does

This workflow simplifies and automates the following steps:

1. Listens for GoHighLevel Opportunity Events: It acts as a webhook listener, waiting for new or updated opportunity events from GoHighLevel.
2. Extracts Contact Information: Upon receiving an event, it extracts essential contact details such as the contact's phone number and name from the GoHighLevel opportunity data.
3. Prepares VAPI Call Data: It constructs the necessary JSON payload for the VAPI API, including the extracted phone number and a dynamic message that incorporates the contact's name.
4. Initiates Outbound Call via VAPI: It makes an HTTP POST request to the VAPI API endpoint to initiate an outbound voice call to the contact.
5. Introduces a Delay (Optional but Recommended): After initiating the call, it includes a configurable wait period. This can be useful for rate limiting or allowing time for the call to connect before any subsequent actions (though no subsequent actions are defined in this specific workflow).

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• GoHighLevel Account: An active GoHighLevel account with opportunities configured.
• VAPI (Voice API) Account: An account with VAPI or a similar Voice API service that allows initiating outbound calls via an HTTP request.
• VAPI API Key/Authentication: The necessary API key or authentication details for your VAPI service to authorize the HTTP requests.
• GoHighLevel Webhook Configuration: You will need to configure a webhook in GoHighLevel to send opportunity events to the n8n Webhook node.

Setup/Usage

1. Import the Workflow: Import this JSON workflow into your n8n instance.
2. Configure GoHighLevel Webhook:
   • In your n8n workflow, activate the "Webhook" node and copy its unique URL.
   • In GoHighLevel, navigate to your workflow automation settings.
   • Create a new workflow or edit an existing one that triggers on "Opportunity Created" or "Opportunity Updated" events.
   • Add a "Webhook" action to this GoHighLevel workflow and paste the n8n Webhook URL you copied.
3. Configure "Edit Fields" Node:
   • The "Edit Fields" (Set) node is configured to extract contact.phone and contact.name from the incoming GoHighLevel data. Ensure these paths match the data structure sent by your GoHighLevel webhook. Adjust if necessary.
4. Configure "HTTP Request" Node (VAPI):
   • Method: Set to POST.
   • URL: Enter your VAPI outbound call API endpoint (e.g., https://api.vapi.ai/call).
   • Headers: Add an Authorization header with your VAPI API key (e.g., Bearer YOUR_VAPI_API_KEY).
   • Body Parameters:
     • Set the "Body Content Type" to JSON.
     • Construct the JSON body, mapping the phone and name from the previous "Edit Fields" node. An example body might look like:

       {
         "phoneNumber": "{{ $json.phone }}",
         "message": "Hello {{ $json.name }}, this is an automated call regarding your recent opportunity."
       }
       

       Adjust the message and other VAPI-specific parameters as needed.
5. Configure "Wait" Node (Optional):
   • The "Wait" node is currently set to 10 seconds. Adjust this duration as per your requirements or remove it if not needed.
6. Activate the Workflow: Once all configurations are complete, activate the workflow in n8n.

Now, whenever an opportunity event occurs in GoHighLevel that triggers your configured webhook, n8n will automatically initiate an outbound call via VAPI to the associated contact.
