02/27/2025, 12:50 PMHi guys,
I am trying to send a custom value (company name) using {{customer.X}}
This is my json:
{
"assistantId": "xxx",
"assistantOverrides": {
"variableValues": {
"custom_json": {{17.json}}
}
},
"customer": {
"number": "{{20.phone}}",
"name": "{{20.full_name}}",
"company_name": "{{20.company_name}}"
},
"phoneNumberId": "xxx"
}
However getting an API error:
Error: 400 Bad Request
{"message":["customer.property company_name should not exist"],"error":"Bad Request","statusCode":400}
This is my variable in VAPI script:
Hello is this {{customer.name}} from {{customer.company_name}}?
Please could you advise what the issue is and how to fix it?
Thanks a lot!

02/27/2025, 1:38 PMThis is not being done correctly.
1. The customer object really can have 5 properties.
I upload a screenshot of the options available for the customer object. You can view them here at the bottom of the Request Body section:
https://docs.vapi.ai/api-reference/calls/create
property company_name is not one of those options.

{{customer.name}} & {{customer.company_name}
This is incorrect. You should change them to be:
{{name}} & {{companyName}}
In the system prompt.
Your variable values must have:
variableValues: {
name: customer.name, companyName: customer.company_name
}
or however your customer object is built in your code.

You would address it like this:
