(PowerBuilder) AWS Security Token Service (STS) AssumeRole

See more AWS Security Token Service Examples

Returns a set of temporary security credentials that you can use to access AWS resources. These temporary credentials consist of an access key ID, a secret access key, and a security token. Typically, you use AssumeRole within your account or for cross-account access.

For more information, see https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html
