You are right Sebastien, like we discussed in the previous thread we do need perform user-registration before making both EC2 SOAP and EC2 Query API calls.
The difference is the steps in the user-registration, 1. For SOAP, cloudstack-aws-api-register --apikey=<User's CloudPlatform API key> --secretkey=< User's CloudPlatform Secret key > --cert=<path/to/cert.pem> --url=http://<cloud-mgmt-server>:7080/awsapi. 2. For REST, http:// <cloud-mgmt-server>:7080/awsapi?Action=SetUserKeys&accesskey=<User's CloudPlatform API key>&secretkey=< User's CloudPlatform Secret key > Additional info: cloudstack-aws-api-register script performs both the actions, SetUserKeys and SetCertificate. * SetUserKeys gives the user's API access and secret keys to AWSAPI so that AWSAPI can call the CloudStack API with these keys. This is required for both Query and SOAP. * SetCertificate registers the user's X.509 certificate with AWSAPI. EC2 requires the client to have a public/private key pair with the public key defined by a X.509 certificate. This is required only for SOAP access only (http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/using-soap-api.html) Thank you, Likitha -----Original Message----- From: Rajesh Battala [mailto:rajesh.batt...@citrix.com] Sent: Friday, December 14, 2012 7:47 PM To: cloudstack-dev@incubator.apache.org Subject: RE: [AWSAPI] user registration >From Likitha I heard we don't need user registration for EC2 Query API. @Likitha can you confirm it.?

Can one of the developers (Prachi, Likitha, Rajesh..) comment on this ? >From a previous thread with Likitha, I thought that user registration was >mandatory even for the EC2 Query API.
