Solving - S3 Access Denied when calling PutObject #The S3 error "(AccessDenied) when calling the PutObject operation" occurs when we try to upload a file to an S3 bucket without having the necessary permissions. Show
 In order to solve the "(AccessDenied) when calling the PutObject operation" error:
Make sure to replace the YOUR_BUCKET placeholder with the name of your s3 bucket. Don't attach this policy as a bucket policy. Rather attach it to the user that is trying to upload files to the S3 bucket or to the corresponding role (e.g. of a lambda function or EC2 instance). Copied! { "Version": "2012-10-17", "Statement": [ { "Action": [ "s3:PutObject", "s3:PutObjectAcl", "s3:GetObject", "s3:GetObjectAcl", "s3:AbortMultipartUpload" ], "Resource": [ "arn:aws:s3:::YOUR_BUCKET", "arn:aws:s3:::YOUR_BUCKET/*" ], "Effect": "Allow" } ] }Note that S3 is a globally distributed service and it might take a minute or two for the policy to take effect. Once the policy is attached to the IAM entity, you will be able to upload files to your S3 bucket. Further Reading #
I tried uploading to s3 and when I see the logs from the s3 bucket logs this is what it says: mybucket-me [17/Oct/2013:08:18:57 +0000] 120.28.112.39 arn:aws:sts::778671367984:federated-user/ BB3AA9C408C0D26F REST.POST.BUCKET avatars/dean%2540player.com/4.png "POST / HTTP/1.1" 403 AccessDenied 231 - 132 - "http://localhost:8080/ajaxupload/test.html" "Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.52 Safari/537.17" -I got an access denied. From where it's pointing I think the only thing that I'm missing out is adding of bucket policy. So here goes. Using my email I could log in to my app and upload an avatar. The bucket name where I want to put my avatar is mybucket-me and in that it has a sub bucket named avatars. -mybucket-me -avatars - //dynamic based on who are logged in -myavatar.png //image uploadedHow do I add a bucket policy so I could grant a federated such as I to upload in s3 or what is the correct statement that I will add on my bucket policy so it could grant me a permission to upload into our bucket? asked Oct 17, 2013 at 11:07

kenorbkenorb 140k74 gold badges650 silver badges700 bronze badges 1 You can attach the following policy to the bucket: { "Version": "2008-10-17", "Id": "Policy1358656005371", "Statement": [ { "Sid": "Stmt1354655992561", "Effect": "Allow", "Principal": { "AWS": [ "arn:aws:sts::778671367984:federated-user/" ] }, "Action": [ "s3:List*", "s3:Get*" ], "Resource": [ "arn:aws:s3:::my.bucket", "arn:aws:s3:::my.bucket/*" ] } ] }to grant the federated user read-only permissions to 'my.bucket'. This policy is not very maintainable because it names this user in particular. To give access to only certain federated users in a more scalable way, it would be better to do this when you call GetFederationToken. If you post your STS code I can help you assigning the policy there, but it is very similar to the above. answered Oct 17, 2013 at 11:30

The URL to the Amazon S3 object doesn't include your user credentials, so the request to the object is anonymous. Amazon S3 returns an Access Denied error for anonymous requests to objects that aren't public.
Why can't I access an object that was uploaded to my Amazon S3 bucket by another AWS account?For these existing buckets, an object owner had to explicitly grant permissions to an object (by attaching an access control list). Otherwise, the bucket owner would be unable to access the object. With S3 Object Ownership, bucket owners can now manage the ownership of any objects uploaded to their buckets.
