I am trying to create a new IAM user (programmatic access only) that has full access to Amazon S3 using PHP SDK.
I looked at https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-iam-2010-05-08.html#createuser and I am not able to figure out what parameter is required to indicate programmatic access only to the user. Does specifying the username alone indicates it to be Programmatic user? Once I create the user, I am assuming, I have to call the "createAccessKey" method for that user to get the access credentials? Is that right?
