### Answer 1. **Dynamic Assistant Prompts**: Yes, Vapi supports creating dynamic assistant prompts. You can personalize an assistant’s messages and prompts using variables, allowing each call to be customized. This is done through

assistantOverrides

with

variableValues

passed to the API or SDK. For example:

json
   {
     "variableValues": {
       "name": "John"
     }
   }

In your prompt templates, you can use variables like

{{name}}

which will be replaced dynamically during the call [(1)]() . 2. **Sharing Assistant URL with Custom Prompt**: Vapi allows creating temporary assistants with custom configurations on the fly via the Web SDK. You can customize properties from the frontend dynamically without creating new assistants for each applicant. Here is a brief example:

javascript
   const assistantOptions = {
     name: "Interview Assistant",
     firstMessage: "Hello, let's start your interview.",
     transcriber: {
       provider: "deepgram",
       model: "nova-2",
       language: "en-US",
     },
     voice: {
       provider: "playht",
       voiceId: "jennifer",
     },
     model: {
       provider: "openai",
       model: "gpt-4",
       messages: [
         {
           role: "system",
           content: `You are an interview assistant. The candidate is {{name}}.`,
         },
       ],
     },
   };
   vapi.start(assistantOptions);

This allows you to send a unique URL for each applicant with their respective prompts/questions without needing to create a new assistant each time [(2)]() .
