Hi, I've been having trouble using GHL tools in VAPI. I'm trying to get the contacts information for the assistant to be able to call the user by their name, or to schedule an appointment. The problems I get: - getting the callers phone number -Inconsistency (It works 1/3 times on average) -If I interrupted the 'Start Request Message' it won't work (Call ID: 7bbe4d06-f7a0-4000-bb48-8e028ff565b3) -Sometimes it takes few tries to be able to get phone number and use it for the tool (call ID: c60c3733-6853-4708-ad59-72a492144068) -Sometimes, when the tool works, it executes 2 or 3 times (Call ID: c9f3320c-46b5-4ed1-a3fc-536a781ccb7d) I've been struggling with this for a week now. Please let me know if you need any more information. https://cdn.discordapp.com/attachments/1415799945180745829/1415799969167704177/image.png?ex=68c485f8&is=68c33478&hm=e849824c9ffd0100b54520f2945aa640739ca4f34ac1396ef0a6f53c6320f6da& https://cdn.discordapp.com/attachments/1415799945180745829/1415799970031992992/image.png?ex=68c485f9&is=68c33479&hm=34ca0e1e439eb0b2245a29b5f4bf741900190216a2d118389f4ab01e457e5074& https://cdn.discordapp.com/attachments/1415799945180745829/1415799970438844426/image.png?ex=68c485f9&is=68c33479&hm=0f7d72d4f01989550ab1cc98f7913576bccf5f4a0d44cbce1d0ec3c02dee5c89&

Suggestion: To reduce "Invalid arguments" errors with

ghl_get_contact

, ensure your assistant always captures the caller's phone number before calling the tool. For example, in your system prompt or logic, add a check like:

js
if (callerPhoneNumber) {
  callTool('ghl_get_contact', { phone: callerPhoneNumber });
} else {
  // Prompt user or handle missing number
}

This helps guarantee the tool receives valid input every time and avoids duplicate or failed executions.

Hi Niko369blt, To address issues with the

ghl_get_contact

tool, ensure you've followed these setup steps: 1. **Verify Configuration**: Make sure your GoHighLevel account is connected to Vapi. You can do this by navigating to the Vapi Dashboard, then going to Providers Keys > Tools Provider > GoHighLevel and checking if it's connected. 2. **Tool Creation**: Confirm the tool was correctly created: - Go to Dashboard > Tools page, and see if the

ghl_get_contact

tool is listed. - Ensure it is configured correctly. This tool requires an email or phone number to search for existing contacts. 3. **Check Authorization**: The tool requires the proper authorization. Make sure you've allowed Vapi access to your GoHighLevel account during setup. 4. **Tool Usage**: Follow the designed workflow to use

ghl_get_contact

before creating new contacts or appointments. This helps prevent duplicate entries. If the tool is still not returning the expected results, consider reviewing the details of your API calls or ensuring there are no connectivity issues between Vapi and GoHighLevel. For further guidance, check the [GoHighLevel Integration guide](https://docs.vapi.ai/tools/go-high-level) for any additional setup details.
