# Function: wrapOpenAI()

```ts theme={null}
function wrapOpenAI<T>(
  openAIClient: T,
  logger?: GalileoLogger,
  ingestionHook?: (request: LogTracesIngestRequest) => void | Promise<void>,
): T;
```

Defined in: [src/handlers/openai/index.ts](https://github.com/rungalileo/galileo-js/blob/main/src/handlers/openai/index.ts)

Wraps an OpenAI instance with logging.

## Type Parameters

### T

`T` *extends* `OpenAIType`

## Parameters

### openAIClient

`T`

The OpenAI instance to wrap.

### logger?

[`GalileoLogger`](/sdk-api/typescript/reference/README/classes/GalileoLogger)

The logger to use. Defaults to a new GalileoLogger instance.

### ingestionHook?

(`request`: [`LogTracesIngestRequest`](/sdk-api/typescript/reference/README/type-aliases/LogTracesIngestRequest)) => `void` | `Promise`\<`void`>

Optional async callback invoked with the trace ingest request payload before sending to the Galileo API. Use this to inspect or modify trace data before ingestion. When provided without a logger, a new GalileoLogger is created with this hook and traces are automatically flushed to the hook after each completed call. No explicit flush() is needed.

## Returns

`T`

The wrapped OpenAI instance.

Usage:

```typescript theme={null}
import { wrapOpenAI } from "galileo";

const openai = wrapOpenAI(new OpenAI({ apiKey: process.env.OPENAI_API_KEY }));

await openai.chat.completions.create({
  model: "gpt-4o",
  messages: [{ content: "Say hello world!", role: "user" }],
});
```
