## Methods

### sendMessage

▸ **sendMessage**(`text`, `opts?`): `Promise`<[`ChatMessage`](../interfaces/ChatMessage.md)\>

Sends a message to the OpenAI chat completions endpoint, waits for the response
to resolve, and returns the response.

If you want your response to have historical context, you must provide a valid `parentMessageId`.

If you want to receive a stream of partial responses, use `opts.onProgress`.

Set `debug: true` in the `ChatGPTAPI` constructor to log more info on the full prompt sent to the OpenAI chat completions API. You can override the `systemMessage` in `opts` to customize the assistant's instructions.

| `text` | `string` |
| `opts` | [`SendMessageOptions`](../modules.md#sendmessageoptions) |
