HMAC authentication 


Securely authenticate with our APIs

Hash-based message authentication code (HMAC) is used to verify the integrity and authenticity of a message and prove that it has not been unlawfully accessed.

HMAC is more secure than basic authentication as it signs the entire request and prevents reply attacks. HMAC is the main authentication method used by AWS, and is recommended for larger organisations and security conscious organisations that deal with sensitive data.
