AWS Lambda (NET 6) & Cognito: How to use Swagger?

Hi,

Given above info, if you need authentication and authorization mechanism with Lambda, you need to include a facade in front of: Api gateway or ALB as pointed out above.

In fact you cannot use lambda function urls, https://docs.aws.amazon.com/lambda/latest/dg/urls-auth.html, as they have IAM authentication only.

You could look into SAM https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/sam-resource-api.html which supports provision of swagger in its template, which then you can test local, but you still will need that facade.

Hope it clarifies ;)

There are several options to access your Lambda. It could be deployed with a Function URL that can be called directly, or it can be fronted with an AWS Elastic Load Balancer (Application Load Balancer) or an API Gateway. Depending on how you set up your architecture, the configuration details change.

Do you mean to use Swagger UI to test your Lambda function, or to define a security scheme with Swagger (JSON/YAML)?

I mean to test my Lambda using Swagger. I test my Lambda in Local environment: all methods etc and do it after deploying Lambda to AWS. It works fine, But now I need to add restrictions who can call methods (RBAC). I'll use Cognito. So the question: how to test the Lambda using Swagger + Cognito authentication + authorization. Customer can test the Lambda without client app and confirm it works correctly,
