Returns a set of temporary security credentials (consisting of an access key ID, a secret access key, and a security token) for a user. A typical use is in a proxy application that gets temporary security credentials on behalf of distributed applications inside a corporate network.

sts_get_federation_token(
Name,
Policy = NULL,
PolicyArns = NULL,
DurationSeconds = NULL,
Tags = NULL
)[required] The name of the federated user. The name is used as an identifier for
the temporary security credentials (such as Bob). For example, you can
reference the federated user name in a resource-based policy, such as in
an Amazon S3 bucket policy.
The regex used to validate this parameter is a string of characters consisting of upper- and lower-case alphanumeric characters with no spaces. You can also include underscores or any of the following characters: =,.@-
An IAM policy in JSON format that you want to use as an inline session policy.
You must pass an inline or managed session policy to this operation. You can pass a single JSON policy document to use as an inline session policy. You can also specify up to 10 managed policy Amazon Resource Names (ARNs) to use as managed session policies.
This parameter is optional. However, if you do not pass any session policies, then the resulting federated user session has no permissions.
When you pass session policies, the session permissions are the intersection of the IAM user policies and the session policies that you pass. This gives you a way to further restrict the permissions for a federated user. You cannot use session policies to grant more permissions than those that are defined in the permissions policy of the IAM user. For more information, see Session Policies in the IAM User Guide.
The resulting credentials can be used to access a resource that has a
resource-based policy. If that policy specifically references the
federated user session in the Principal element of the policy, the
session has the permissions allowed by the policy. These permissions are
granted in addition to the permissions that are granted by the session
policies.
The plaintext that you use for both inline and managed session policies
can't exceed 2,048 characters. The JSON policy characters can be any
ASCII character from the space character to the end of the valid
character list (U+0020 through U+00FF). It can also include the tab
(U+0009), linefeed (U+000A), and carriage return (U+000D) characters.
An Amazon Web Services conversion compresses the passed inline session
policy, managed policy ARNs, and session tags into a packed binary
format that has a separate limit. Your request can fail for this limit
even if your plaintext meets the other requirements. The
PackedPolicySize response element indicates by percentage how close
the policies and tags for your request are to the upper size limit.
The Amazon Resource Names (ARNs) of the IAM managed policies that you want to use as a managed session policy. The policies must exist in the same account as the IAM user that is requesting federated access.
You must pass an inline or managed session policy to this operation. You can pass a single JSON policy document to use as an inline session policy. You can also specify up to 10 managed policy Amazon Resource Names (ARNs) to use as managed session policies. The plaintext that you use for both inline and managed session policies can't exceed 2,048 characters. You can provide up to 10 managed policy ARNs. For more information about ARNs, see Amazon Resource Names (ARNs) and Amazon Web Services Service Namespaces in the Amazon Web Services General Reference.

The duration, in seconds, that the session should last. Acceptable durations for federation sessions range from 900 seconds (15 minutes) to 129,600 seconds (36 hours), with 43,200 seconds (12 hours) as the default. Sessions obtained using root user credentials are restricted to a maximum of 3,600 seconds (one hour). If the specified duration is longer than one hour, the session obtained by using root user credentials defaults to one hour.
A list of session tags. Each session tag consists of a key name and an associated value. For more information about session tags, see Passing Session Tags in STS in the IAM User Guide.
This parameter is optional. You can pass up to 50 session tags. The plaintext session tag keys can’t exceed 128 characters and the values can’t exceed 256 characters. For these and additional limits, see IAM and STS Character Limits in the IAM User Guide.

You can pass a session tag with the same key as a tag that is already attached to the user you are federating. When you do, session tags override a user tag with the same key.
Tag key–value pairs are not case sensitive, but case is preserved. This
means that you cannot have separate Department and department tag
keys. Assume that the role has the Department=Marketing tag and you
pass the department=engineering session tag. Department and
department are not saved as separate tags, and the session tag passed
in the request takes precedence over the role tag.
