What this card says
What it is
AssumeRole returns AccessKeyId, SecretAccessKey, SessionToken, and Expiration. All three secret values must be used together until Expiration.
SessionToken
Why it matters
Missing SessionToken makes API calls fail even if key and secret look valid. Expired sessions fail until you AssumeRole again.
How / example
aws sts assume-role … then export the three fields and call aws sts get-caller-identity to see the assumed-role ARN.
