# renderSwml

> Render the complete SWML document by assembling all 5 phases.

Render the complete SWML document by assembling all 5 phases: pre-answer, answer,
post-answer, AI, and post-AI verbs. This is called automatically by the Hono route
handler on each incoming request, but can also be called manually for testing or
debugging.

## **Parameters**

**`callId`** `string`

Optional call ID to use for session tokens. Auto-generated if omitted.

---

**`modifications`** `Record<string, unknown>`

Optional object (typically returned from
[`onSwmlRequest()`](/docs/server-sdks/reference/typescript/agents/agent-base/on-swml-request))
merged into the AI verb config before rendering. `global_data` is deep-merged;
all other keys override AI config fields directly.

---

## **Returns**

`string` -- The rendered SWML document as a JSON string.

## **Example**

```typescript {7}
import { AgentBase } from '@signalwire/sdk';

const agent = new AgentBase({ name: 'support', route: '/support' });
agent.setPromptText('You are a helpful assistant.');
agent.addHints(['SignalWire', 'SWML']);

const swml = agent.renderSwml();
console.log(JSON.parse(swml));
```
