To use existing Amazon Pinpoint resources with your Amplify backend or frontend application, use the `addOutput` method to surface backend resource outputs to the `amplify_outputs.json` file:

```ts title="amplify/backend.ts"
import { defineBackend } from "@aws-amplify/backend"

const backend = defineBackend({})

backend.addOutput({
  analytics: {
    amazon_pinpoint: {
      aws_region: "<your-aws-region>",
      app_id: "<your-pinpoint-app-id>",
    },
  },
})
```

<!-- Platform: javascript, react-native, angular, nextjs, react, vue -->
## Configuring client library directly

Alternatively, you can configure the client library directly using `Amplify.configure()`. This manual setup enables you to use your existing Amazon Pinpoint resource in your app.

```ts title="src/main.ts"
import { Amplify } from 'aws-amplify';
import { parseAmplifyConfig } from "aws-amplify/utils";
import outputs from '../amplify_outputs.json';

const amplifyConfig = parseAmplifyConfig(outputs);

Amplify.configure({
  ...amplifyConfig,
  Analytics: {
    ...amplifyConfig.Analytics,
    Pinpoint: {
      // REQUIRED -  Amazon Pinpoint App Client ID
      appId: 'XXXXXXXXXXabcdefghij1234567890ab',

      // REQUIRED -  Amazon service region
      region: 'us-east-1',

      // OPTIONAL - How many events can be buffered at once.
      bufferSize: 1000,

      // OPTIONAL - How many events will be flushed from the buffer per batch.
      flushSize: 100,

      // OPTIONAL - The interval in milliseconds to perform a buffer check and flush if necessary.
      flushInterval: 5000, // 5s

      // OPTIONAL - The limit for failed recording retries.
      resendLimit: 5
    }
  }
});
```

## Update your IAM Policy

Amazon Pinpoint requires an AWS Identity and Access Management (IAM) policy in order to use the `record` and `identifyUser` APIs:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": ["mobiletargeting:UpdateEndpoint", "mobiletargeting:PutEvents"],
      "Resource": ["arn:aws:mobiletargeting:*:<your-account-id>:apps/<your-pinpoint-app-id>*"]
    }
  ]
}
```
