Signing Amazon Route 53 API Requests
Requests must be signed using an access key ID and a secret access key. We strongly recommend that you do not use your Amazon Web Services account credentials for everyday work with Route 53. You can use the credentials for a user or you can use Amazon STS to generate temporary security credentials.
To sign your API requests, we recommend that you use Amazon Signature Version 4. For more information, see Access Management in the IAM User Guide.
