# Create web call

> POST https://api.nabrah.ai/api/ext/web/make-web-call

Group: Web calls. Page: https://www.nabrah.ai/en/docs/api-reference/web-calls/create-web-call

Create a web call: start a browser/WebRTC voice session with an agent and receive a connection token. Designed to be called from your frontend so a user can talk to the agent directly in the browser. Provide the agent_id and optionally an identity for the participant, prompt variables, and free-form extra_data; the returned token is used by your WebRTC client to join the live audio session. This is the canonical web-call endpoint; /api/ext/make-web-call is an equivalent alias kept for backward compatibility.

## Request fields

- **agent_id**: UUID of the agent that will answer the web call. Fetch agents with GET /api/ext/agent. Fields: `agent_id`.
- **identity**: Optional participant identity for the realtime session — useful to associate the connection with a known user. Fields: `identity`.
- **variables**: Optional key/value map of template variables exposed to the agent's prompt during the session. Fields: `variables`.
- **extra_data**: Optional free-form data injected into the call context. Fields: `extra_data`.

## Response

- **token**: Connection token returned for joining the live voice session from a browser/WebRTC client. Short-lived; mint a new one per session. Fields: `token`.

## Related

- **/api/ext/make-web-call**: Identical backward-compatible alias. Prefer this canonical path (/api/ext/web/make-web-call).
- **GET /api/ext/call/{call_id}**: After the session, the web call appears as a call record retrievable by its id.

## Authorization

- `X-API-Key` (string, header, required): your workspace API key.

## Body (application/json)

### Example: Minimal

Start a web call with just an agent.

}
```

### Example: Full

Web call with participant identity, variables, and extra context.

```json
{
  "agent_id": "00000000-0000-4000-8000-000000000000",
  "identity": "user-12345",
  "variables": {
    "customer_name": "Ahmed"
