AWS cli documentation change

Service: cli · 2026-02-28 · Documentation low

File: cli/latest/reference/cognito-idp/respond-to-auth-challenge.md

Summary

Updated CLI version reference, added --cli-error-format option, and expanded ClientMetadata documentation with Lambda trigger details

Security assessment

Changes include version updates, error formatting options, and enhanced Lambda trigger documentation. No security vulnerabilities are addressed, and the documentation improvements focus on existing workflow explanations rather than new security features. The ClientMetadata clarifications relate to standard functionality rather than security-specific enhancements.

-> You create custom workflows by assigning Lambda functions to user pool triggers. When you use the RespondToAuthChallenge API action, Amazon Cognito invokes any functions that are assigned to the following triggers: _post authentication_ , _pre token generation_ , _define auth challenge_ , _create auth challenge_ , and _verify auth challenge_ . When Amazon Cognito invokes any of these functions, it passes a JSON payload, which the function receives as input. This payload contains a `clientMetadata` attribute, which provides the data that you assigned to the ClientMetadata parameter in your RespondToAuthChallenge request. In your function code in Lambda, you can process the `clientMetadata` value to enhance your workflow for your specific needs.
