Begin by setting up your DynamoDB table in AWS if you haven't already. Log into your AWS Management Console, navigate to DynamoDB, and create a new table. Define your primary key attributes and any other required fields to accommodate the data you plan to store.

Create an IAM user in AWS with permissions to access DynamoDB. In AWS IAM, generate security credentials (Access Key ID and Secret Access Key) for your user. Ensure the user has policies attached that grant read and write permissions to your DynamoDB table.

Since n8n supports custom scripts, install the AWS SDK for JavaScript, which will allow you to interact with DynamoDB. In your terminal, run the command:
```bash
npm install aws-sdk
```
This will add the necessary AWS libraries to your environment.

Use n8n�s built-in nodes to fetch or process the data you wish to move to DynamoDB. This might involve HTTP requests, database queries, or other operations supported by n8n. Ensure that the data is structured in a way that matches the schema of your DynamoDB table.

Within n8n, securely store your AWS credentials. Use n8n's credential management feature to store your AWS Access Key ID and Secret Access Key, ensuring they are accessible to your workflows but not exposed.

Use n8n�s Function or Function Item nodes to write a custom JavaScript script that uses the AWS SDK to insert data into DynamoDB. Here�s a basic outline of the script:
```javascript
const AWS = require('aws-sdk');
// Configure AWS SDK
AWS.config.update({
region: 'your-region', // e.g., 'us-east-1'
accessKeyId: 'your-access-key-id',
secretAccessKey: 'your-secret-access-key'
});
const dynamoDB = new AWS.DynamoDB.DocumentClient();
const params = {
TableName: 'your-table-name',
Item: {
// Specify your item attributes here
'PrimaryKey': data.primaryKeyValue,
'Attribute1': data.attribute1Value,
// Add more attributes as necessary
}
};
dynamoDB.put(params, function(err, data) {
if (err) {
console.error("Unable to add item. Error JSON:", JSON.stringify(err, null, 2));
} else {
console.log("Added item:", JSON.stringify(data, null, 2));
}
});
```
Replace placeholder values with actual data and configuration details.

Once your script is ready, execute the n8n workflow. Monitor the execution by checking n8n�s logs for any errors or output messages. Verify the data insertion by checking your DynamoDB table in the AWS Management Console to ensure the data has been transferred correctly.
This guide outlines a way to manually transfer data from n8n to DynamoDB using custom scripts and AWS SDK, ensuring a direct and integration-free approach.
