# Notification.requestAgreement

> Functional API `requestNotificationAgreement`You can use the same feature with it as well.

### Feature description

Request the notification consent screen, and pass the consent result `onEvent` as a callback. Toss app Android/iOS `5.255.0` It can be used on the above.

`options.templateCode`In options.templateCode, please enter the template code created in Apps in Toss Console > Mini App > Smart Sending.

It works in an event-driven style, and as a return value, it gives you a function that releases the App Bridge callback. When the result comes in, be sure to release it.

Before calling `Notification.requestAgreement.isSupported()`you can check whether it is supported. If you call it on an unsupported version, `UNSUPPORTED_APP_VERSION` An error occurs. The functional API `requestNotificationAgreement`attempts to subscribe regardless of version.

### Type

```ts
Notification.requestAgreement(params: RequestNotificationAgreementOptions): () => void;
```

**Params**

```ts
interface RequestNotificationAgreementOptions {
  options: { templateCode: string };
  onEvent: (result: { type: NotificationAgreementResult }) => void;
  onError: (error: unknown) => void | Promise<void>;
}

type NotificationAgreementResult =
  "newAgreement" | "alreadyAgreed" | "agreementRejected";
```

**Response**

Returns a cleanup function that releases the App Bridge callback.

### Error

Error codes are `onError`can be received as, or wrapped around the `try/catch`errors caught in `error.code` value.

| ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `UNSUPPORTED_APP_VERSION` | If the running version of the Toss app doesn't support this feature, it occurs immediately upon call. `Notification.requestAgreement.isSupported()`Check in advance with `error.message`and, if it occurs, show the user the (update guidance message). |

### Example code

```js
import { Notification } from "@apps-in-toss/web-framework";

try {
  const cleanup = Notification.requestAgreement({
    options: { templateCode: "test-template-code" },
    onEvent: (result) => {
      console.log(result.type); // 'newAgreement' | 'alreadyAgreed' | 'agreementRejected'
      cleanup();
    },
    onError: (error) => {
      console.error(error);
      cleanup();
    },
  });
} catch (error) {
  console.error(error);
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers-apps-in-toss.toss.im/documentation/api-and-sdk-en/sdk/domains-api/notification/notification.requestagreement.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
