I would like to have our Vapi Assistant to greet the customer with their name. I used this page in the documentation as a reference: https://docs.vapi.ai/assistants/dynamic-variables The problem is, everytime the bot calls the customer it doesn't greet them by mentioning the customer's name. Currently, I have a custom webhook setup in a workflow in GHL to connect it to Vapi and make the call. In the webhook, I wrote this:

{
  "assistantId": "f3b1c374-1e5b-47e8-aa03-8cdbe0df67c8",
  "phoneNumberId": "e640fea1-5a5f-4b2f-9e6c-0f65e4e9ccfd",
  "assistantOverrides": {
    "variableValues": {
      "name": "{{contact.name}}",
      "Property": "{{contact.address1}}"
    }
  },
  "customer": {
    "number": "{{contact.phone_raw}}"
  }
}

And in the Assistant's System Prompt, an instruction on how to greet the customer: "When greeting the customer, say something like 'Hi, {{name}}!'" Is this how you properly setup the webhook in JSON and how you reference the variable within the system prompt? If not, please provide me some corrections. Thank you!

Your JSON structure and system prompt reference look correct! One thing to check is if GHL is properly replacing

{{contact.name}}

with the actual name before sending to Vapi. Try testing with a hardcoded name first:

json
"variableValues": {
  "name": "John Doe",
  "Property": "{{contact.address1}}"
}

If this works, the issue is likely with how GHL is processing the variable. Source: - [Dynamic Variables in Vapi](https://docs.vapi.ai/assistants/dynamic-variables)

Hi Have you been able to fix this?

Hi

Testing with a hardcoded name worked. The Assistant actually mentioned then name I inputted. But whenever I switch to a custom field inside the webhook, the Assistant is unable to mention the name during the call. So the issue is likely with how GHL is passing the variable. So far, I haven't figured out a fix for this one. The workaround I'm using is just having multiple workflows for each client so that I can customize each workflow's webhook with the client's name hardcoded in it. Until I'm able to figure out how to pass the variables properly from GHL to Vapi.

Your JSON setup looks correct, but in your system prompt, replace the instruction-style text with a direct greeting like: “Hi, {{name}}!”, this allows Vapi to substitute the actual name instead of saying the placeholder..
