KAS uses Basic HTTP Auth. All requests must have a correct Authorization header. You can create the Credential for Basic Auth by using username as AccessKey ID and password as SecretAccessKey obtained on KAS Console.

NOTE

The KAS account credentials grant access to all services of KAS and own all rights to the Kaia account created by Wallet API, which means they can execute value transfer of assets on the Kaia account (such as KAIA) or a Transaction execution. To keep your KAS/Kaia account secure, do not share your KAS API Secret Access Key with others and manage it safely.
