I'm trying to setup security on an API using Cognito user pools. I'm getting back 401 Unauthorized. The API and User Pools are existing, and I've been using the user pool to log into an application. I'm now trying to secure the API calls. I created an authorizer on the API, Then I added the authorizer to one GET method in the API Then finally I tried to test the API in Postman. I'm using the AWS Signature authorization. Calling the method returns 401. The method functioned before with no security, and turning off the authorizer makes it work again (without security). Any ideas what step I'm

I'm doing a proof of concept for federating SAML into Cognito. I've setup Shibboleth v3, and once I finally got the log level set, I can see the SAML being sent back to Cognito, which just redirects to my configured page with ?error_description=Error+in+SAML+response+processing%3A+Invalid+SAML+metadata.+&error=server_error in the URL. The user pool in Cognito is set to require an email address, and I think I've got the attribute mapping set correctly, but it's not really easy to tell. Here's the SAML I'm seeing in the logs (minus a couple of URLs for anonymization's sake): <?xml version="1.0"

How do you refresh the access token using Cognito for Android? The documentation suggest the following ( https://docs.aws.amazon.com/cognito/latest/developerguide/using-amazon-cognito-user-identity-pools-android-sdk.html ): // Implement authentication handler AuthenticationHandler handler = new AuthenticationHandler { @Override public void onSuccess(CognitoUserSession userSession) { // Authentication was successful, the "userSession" will have the current valid tokens // Time to do awesome stuff } @Override public void getAuthenticationDetails(final AuthenticationContinuation continuation,

Basically I'm using a developer authenticated identity to authenticate my users. Even though this error is showing: AWSiOSSDKv2 [Verbose] AWSURLResponseSerialization.m line:87 | -[AWSJSONResponseSerializer responseObjectForResponse:originalRequest:currentRequest:data:error:] | Response body: [{"__type":"InvalidParameterException","message":"Please provide a valid public provider"}] 2015-10-20 17:50:19.251 BusyTime[56549:7365231] AWSiOSSDKv2 [Error] AWSCredentialsProvider.m line:435 | __73-[AWSCognitoCredentialsProvider getCredentialsWithCognito:authenticated:]_block_invoke |

I am trying to use 'Authenticate using Cognito-Identity with Cognito user pool' in my Android application. My Cognito user pool authentication works well, when I run that separately and I had seen a JWTToken as well. When I run the the 'PubSub' sample application with Unauthenticated role, it worked as expected. When I integrate these two features in one application, the application threw following error.
