# Create a Pull Event SQS Function using Blueprint
> This tutorial explains how to set up an AWS Lambda function that polls an SQS queue and processes incoming messages using a blueprint.
In this tutorial, you’ll learn how to set up an AWS Lambda function that polls an SQS queue and processes incoming messages. We’ll use the built-in SQS blueprint, configure permissions, and verify the end-to-end flow.
## Prerequisites
* An existing SQS queue named `KodeKloudDemoQueue`
* IAM permissions to create Lambda functions and roles
* Basic familiarity with AWS Lambda and Amazon SQS
## 1. Navigate to the AWS Lambda Console
1. Open the [AWS Management Console][aws-console]
2. In the search bar, type **Lambda** and select **AWS Lambda**
## 2. Create a New Function from a Blueprint
1. Click **Create function**
2. Select the **Blueprint** tab
3. Enter **SQS** in the filter box and choose the **sqs-invoke-lambda** blueprint
4. Click **Configure**
### Function Settings
* **Function name**: `KodeKloudSQSDemo`
* **Execution role**: Keep **Create a new role from AWS policy templates**
Scroll to **Policy templates** and confirm **Amazon SQS Poller** (or **Amazon SQS Pull event permissions**) is checked. Lambda requires these permissions to read and delete messages from your queue.
* **Role name**: `demo-lambda-sqs-role`
## 3. Configure the SQS Trigger
Under **Configure triggers**, pick your `KodeKloudDemoQueue` queue.
| Parameter | Value | Description |
| ------------ | ----- | -------------------------------------------------- |
| Batch size | 1 | Number of messages retrieved per Lambda invocation |
| Batch window | 1 s | Maximum wait time before invocation |
You can expand **Additional settings** to apply JSON filters or configure batch-item failure reporting. For this demo, we’ll skip filters.
## 4. Review and Deploy the Handler Code
The blueprint generates this sample Node.js handler:
```javascript theme={null}
console.log('Loading function');
exports.handler = async (event) => {
for (const { messageId, body } of event.Records) {
console.log('SQS message %s: %j', messageId, body);
}
return `Successfully processed ${event.Records.length} messages.`;
};
```
Click **Create function**. AWS will provision your Lambda and attach the SQS trigger automatically.
## 5. Send a Test Message to SQS
1. In the AWS Console search bar, select **Simple Queue Service**
2. Open **KodeKloudDemoQueue**
3. Click **Send and receive messages**, enter **KodeKloud Demo Test** as the body, and hit **Send message**
## 6. Verify Lambda Invocation in CloudWatch
1. Return to the Lambda console for `KodeKloudSQSDemo`
2. Select the **Monitor** tab
3. Check **Invocations** and **Errors** in the CloudWatch metrics
Click **View logs in CloudWatch** to inspect the log stream. You should see entries for your loaded function and the test message body.
## Next Steps
You’ve successfully:
* Created a Lambda function from the SQS blueprint
* Configured IAM roles and pull permissions
* Deployed an SQS trigger and processed a test message
Extend this workflow by integrating with SNS, writing to DynamoDB, or chaining additional Lambda functions.
