## What it does

The skill sends requests to the Vapi `/call` endpoint to trigger outbound phone calls and web sessions. You can reference an existing assistant by `assistantId` or define a transient assistant inline with a custom prompt and voice. It also handles basic batch calls across multiple phone numbers.

It requires a valid `VAPI_API_KEY` and internet access. Calls can be delayed using `schedulePlan` with `earliestAt` and `latestAt` timestamps. You can pass arbitrary JSON in `metadata` to supply context like order IDs to the voice assistant. The skill also covers checking call status from `queued` to `ended` and pulling recordings or transcripts.

This tool handles bounded, single-request operations. If you need multi-contact management with cancellation and webhooks, the author advises using `create-campaign` instead. Automated calls also require prior consent under TCPA regulations, so verifying compliance is essential before dialling real numbers.

## Install

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add VapiAI/skills --skill create-call -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/create-call/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

```

2. **Platform CLI**
```bash
gemini skills install https://github.com/VapiAI/skills --path create-call
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/create-call/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add VapiAI/skills --skill create-call -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/VapiAI/skills/tree/HEAD/create-call/SKILL.md

## When to use it
- place a test phone call using a Vapi assistant
- start a browser-based web call without a phone number
- schedule an outbound call for a future time window
- fetch call recordings, summaries, and transcripts

## Example prompts
- Call +11234567890 using assistant-id and phoneNumberId via the Vapi API
- Schedule a call to +11234567890 between 14:00 and 15:00 UTC using schedulePlan
- Get the transcript and status for call ID call-uuid

# Vapi Call Creation

Initiate outbound phone calls, web calls, and batch calls using Vapi's API. Connect your voice assistants to real phone numbers and test them programmatically.

> **Setup:** Ensure `VAPI_API_KEY` is set. See the `setup-api-key` skill if needed.

## Quick Start — Outbound Phone Call

### cURL

```bash
curl -X POST https://api.vapi.ai/call \
  -H "Authorization: Bearer $VAPI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "assistantId": "your-assistant-id",
    "phoneNumberId": "your-phone-number-id",
    "customer": {
      "number": "+11234567890"
    }
  }'
```

### TypeScript (Server SDK)

```typescript
import { VapiClient } from "@vapi-ai/server-sdk";

const vapi = new VapiClient({ token: process.env.VAPI_API_KEY! });

const call = await vapi.calls.create({
  assistantId: "your-assistant-id",
  phoneNumberId: "your-phone-number-id",
  customer: {
    number: "+11234567890",
  },
});

console.log("Call created:", call.id);
```

### Python

```python
import requests
import os

response = requests.post(
    "https://api.vapi.ai/call",
    headers={
        "Authorization": f"Bearer {os.environ['VAPI_API_KEY']}",
        "Content-Type": "application/json",
    },
    json={
        "assistantId": "your-assistant-id",
        "phoneNumberId": "your-phone-number-id",
        "customer": {"number": "+11234567890"},
    },
)

call = response.json()
print(f"Call initiated: {call['id']}")
```

## Call Types

### Outbound Phone Call

Requires an assistant, a Vapi phone number, and a customer number.

```json
{
  "assistantId": "assistant-id",
  "phoneNumberId": "phone-number-id",
  "customer": {
    "number": "+11234567890",
    "name": "John Doe",
    "numberE164CheckEnabled": true
  }
}
```

### Web Call

For browser-based calls — no phone number needed. Use the Vapi Web SDK on the client side.

```json
{
  "assistantId": "assistant-id"
}
```

Client-side (JavaScript):
```javascript
import Vapi from "@vapi-ai/web";

const vapi = new Vapi("your-public-key");
vapi.start("your-assistant-id");
```

### Transient Assistant Call

Define an assistant inline instead of referencing a saved one:

```json
{
  "assistant": {
    "name": "Quick Test",
    "firstMessage": "Hello! This is a test call.",
    "model": {
      "provider": "openai",
      "model": "gpt-4.1",
      "messages": [
        {
          "role": "system",
````
