By default, the token expires after 30 days. We want to allow users to create an account on our site and be able to log in. You can use the tokens to grant your users access to your own server-side resources, or to the Amazon API Gateway. You can create APIs that access AWS or other web services, as well as data stored in the AWS cloud. This is an example of calling a Lambda using the. js and Express - authorize. They were released in April of 2016, and these prerequisites might and probably will change. The Cognito authorization tokens expire within an hour and AWSMobileClient does not provide a way to refresh them, so I also provided a workaround in this post. Those tokens are used to get temporary AWS credentials from Identity Pools. If you use ASK CLI to manage skills that use AWS Lambda for the skill's backend code, then it also stores a reference to your Amazon Web Services (AWS) credentials. AWS ARNs support a partition field that identifies which AWN partition contains the resource. The token is sent as a parameter in the url and the client must extract this parameter and send it as-is to this action. I was recently doing some work related to AWS Cognito, which I wasn’t previously familiar with, and it turns out to be pretty interesting.
