## Authentication

### Lambda, S3 and SNS

To authenticate with AWS services Lambda, S3, and SNS, you need to provide Access Key Id and Secret Access Key. You can create a new user in the AWS IAM console (<https://console.aws.amazon.com/iam/home>) and assign the necessary permissions to that user.

The neccessary permissions depend on the services and components you want to use. For example, if you want to use the `New S3 Object` component, you need to assign the `AmazonS3ReadOnlyAccess` policy to your user. If you want to use the `Send SNS Message` component, you need to assign the `AmazonSNSFullAccess` policy.
