identityValidationExpression property
A validation expression for the incoming identity token. For
TOKEN authorizers, this value is a regular expression. For
COGNITO_USER_POOLS authorizers, API Gateway will match the
aud field of the incoming token from the client against the
specified regular expression. It will invoke the authorizer's Lambda
function when there is a match. Otherwise, it will return a 401 Unauthorized
response without calling the Lambda function. The validation expression does
not apply to the REQUEST authorizer.
Implementation
