Besides already having a hosted DNS zone under AWS Route 53, you need to set up the following in the AWS IAM console:

• Create a user.

• Write down the "Access Key ID" and "Secret Access Key" credentials.

• Click on the newly created user to edit its properties. Click Inline Policies to create one. Use the Policy Generator:

  • Effect: Allow
  • AWS Service: Amazon Route 53
  • Actions: select only "ChangeResourceRecordSets"
  • Amazon Resource Name (ARN): arn:aws:route53:::hostedzone/%ID%
    • You can get the ID of your hosted zone from the list of the "Hosted zones" in your AWS Route 53 service.
    • Example: arn:aws:route53:::hostedzone/Z148QEXAMPLE8V

• Click Next. The final Policy Document would look something like:

  {
    "Version": "2012-10-17",
    "Statement": [
      {
        "Sid": "Stmt1456599587000",
        "Effect": "Allow",
        "Action": ["route53:ChangeResourceRecordSets"],
        "Resource": ["arn:aws:route53:::hostedzone/Z148QEXAMPLE8V"]
      }
    ]
  }

• Click "Apply Policy".
