Note: This example policy includes only the minimum permissions required for an individual IAM user to download and upload to an encrypted S3 bucket. You can modify or expand the permissions based on your use case.

Amazon S3 is an online file storage system that provides developers and IT teams with secure, durable, and highly-scalable cloud storage. Amazon S3 can be used alone, or together with other services including Amazon Elastic Compute Cloud (Amazon EC2), Amazon Elastic Block Store (Amazon EBS), and Amazon Glacier, as well as third-party storage repositories and gateways.
File Upload Among Us
The following diagram shows how my uploading is done using the 3 AWS services, API Gateway, Lambda and S3. Figure 1: Service Integration First Lets focus on uploading an image to S3.
2. Open the IAM console from the account that the IAM user belongs to. Add a policy to the IAM user that grants the permissions to upload and download from the bucket, as well as work with the AWS KMS key that's associated with the bucket.
For cross-account scenarios, consider granting s3:PutObjectAcl permissions so that the IAM user can upload an object. Then, grant the bucket's account full control of the object (bucket-owner-full-control). Additionally, consider granting s3:ListBucket permissions, which is required for running a sync operation, or a recursive copy operation. You can use a policy that's similar to the following:

S3 Rest Api Upload File
Note: For the first Resource value, enter the ARN for the bucket with a wildcard character to indicate the objects in the bucket. For the second Resource value, enter the ARN for the bucket. For the third Resource value, enter the AWS KMS key's ARN.
