QUESTION
I am having trouble sending specific JWT authorization claims information derived from the Authorization header of a request to an API Gateway REST API endpoint (with non-proxy Lambda integration). The endpoint is secured with a Cognito User Pool Authorizer with Login with Amazon as the identity provider. From the Cloudwatch execution logs of API Gateway, I can see the JWT authorizer claims:
...ANSWER
Answered 2022-Mar-05 at 02:53Turns out I am supposed to deploy the API every time I make a change to the VTL mapping template! Just hitting the [Save] button after modifying the template does not allow the change to take effect. AWS documentation should be updated, since it is not apparent when the API should be re-deployed.
Also, since the value of the identities key in the JWT authorizer claims is a String, I needed to make a slight modification to the above mapping template on the userId property.
QUESTION
As mentioned in step-3 of this blog by AWS, I have created a role to invoke sagemaker endpoint. But, when I deploy the API to a stage, I get "AWS ARN for integration contains invalid action" and I can't deploy the stage.
blog suggested to select API Gateway under services and to keep on next, but didn't mention which policy will be attached. and also that another inline policy to invoke a specific sagemaker endpoint to be created and attached.
and as mentioned in AWS Docs:
It must also have API Gateway declared (in the role's trust relationship) as a trusted entity to assume the role.
my role also have the trust-relationshp:
What's missing in my role that led to the error?
...ANSWER
Answered 2022-Feb-25 at 09:30Check in all your API methods that you haven't specified "Use Action Name" for any integration request, and then left the "Action" field blank. If you do the "AWS ARN for integration contains invalid action" error message will be shown.

I have an angular frontend shipping form and when I click submit, the values reach the backend, but not the userId. My app authenticates with the cognito user pool and I get the token.
but I can't seem to pass the userId.
I added $context.authorizer.principalId per the documentation. I also tried $context.authorizer.claims.userId but same issue.

QUESTION
I'm trying to use the AWS_CDK for python to provision an apigateway integration. The typescript on https://pypi.org/project/aws-cdk.aws-apigateway/1.4.0/ is helpful, as is the unchecked python translation on https://docs.aws.amazon.com/cdk/api/latest/python/aws_cdk.aws_apigateway.README.html but it's not quite right.
I've tried to get the python version correct but I'm still missing something in the translation from TS to python. Currently my code snippet is;
...ANSWER
Answered 2020-May-14 at 06:08So after a bunch more research, the issue was with the translation from TS to Python. It's important to remember that where parameters e.g. the value of integration_response, it is still TS. I found
I also found adding api_gateway method responses a bit non-intuitive as well, so in my working example below I've included it.
QUESTION
My users login to my application through a microservice that connects to cognito (the request is proxied via API gateway)
They get a session token.
Once logged in, they need to put some files to S3.
I want to give them temporary credentials using STS but to call sts.AssumeRoleWithWebIdentity I need a web identity token.
How can I get a web identity token with a session token as input?
I wrote a temporary lambda (node) that returns STS credentials upon logging with a username and password:
...ANSWER
Answered 2020-Feb-18 at 13:32A few checks first:
- let cognito authenticated user to "masquerade" under an iam role, to do that we use trust relationships, for quick you can reuse the iam role that get assigned to your cognito identity pool.
- grant that iam role a policy to access to s3 bucket
Once done:
Run cognitoidentity.getCredentialsForIdentity(...) again, it will go through sts first, thus you don't have to call sts assume role api. If successful, the response should have AccessKeyId, SecretKey and SessionToken. These are expiry aws creds that have access to s3 and will be gone after an hour (unless set). Use them as normal session authentication.
QUESTION
I have a Lambda function that is tied to API Gateway and i am trying to fetch the path and stage from either event or context object that are passed to the Lambda function.
The mapping template generated by the AWS console is below:
...ANSWER
Answered 2020-Feb-12 at 14:26You must check "Lambda Proxy Integration" in your method integration on API gateway, to receive the stage information.
To use a stage variable to customize the HTTP integration endpoint, you must first configure a stage variable of a specified name, e.g., url, and then assign it a value, e.g., example.com. Next, from your method configuration, set up an HTTP proxy integration, and instead of entering the endpoint's URL, you can tell API Gateway to use the stage variable value, http://${stageVariables.url}. This value tells API Gateway to substitute your stage variable ${} at runtime, depending on which stage your API is running. You can reference stage variables in a similar way to specify a Lambda function name, an AWS Service Proxy path, or an AWS role ARN in the credentials field.
