Use the [AWS Cloud Development Kit (AWS CDK)](https://docs.aws.amazon.com/cdk/latest/guide/home.html) to create an [Amazon Kinesis Data Stream](https://aws.amazon.com/kinesis/data-streams/) and grant your app the permissions it needs. For more on adding custom AWS resources to your Amplify backend, see [Custom resources](/[platform]/build-a-backend/add-aws-services/custom-resources/).

## Set up a Kinesis stream

```ts title="amplify/backend.ts"
import { defineBackend } from "@aws-amplify/backend";
import { auth } from "./auth/resource";
import { data } from "./data/resource";
import { Policy, PolicyStatement } from "aws-cdk-lib/aws-iam";
import { Stream } from "aws-cdk-lib/aws-kinesis";
import { Stack } from "aws-cdk-lib/core";

const backend = defineBackend({
  auth,
  data,
});

const kinesisStack = backend.createStack("kinesis-stack");

// Create a Kinesis stream
const kinesisStream = new Stream(kinesisStack, "KinesisStream", {
  streamName: "myKinesisStream",
  shardCount: 1,
});

// Grant PutRecords permission to authenticated users
const kinesisPolicy = new Policy(kinesisStack, "KinesisPolicy", {
  statements: [
    new PolicyStatement({
      actions: ["kinesis:PutRecords"],
      resources: [kinesisStream.streamArn],
    }),
  ],
});

backend.auth.resources.authenticatedUserIamRole.attachInlinePolicy(kinesisPolicy);
```

If you are not using the CDK, ensure your authenticated IAM role has the `kinesis:PutRecords` permission on your target stream:

```json
{
  "Version": "2012-10-17",
  "Statement": [{
    "Effect": "Allow",
    "Action": "kinesis:PutRecords",
    "Resource": "arn:aws:kinesis:<region>:<account-id>:stream/<stream-name>"
  }]
}
```

For more information, see the [Amazon Kinesis Developer Documentation](https://docs.aws.amazon.com/streams/latest/dev/controlling-access.html).

## Next steps

Use the [Kinesis Data Streams client](/[platform]/frontend/analytics/kinesis/) to stream data from your app.
