AK/SK Authentication

When you use API Gateway to send requests to underlying services, the requests are signed using the AK and SK.

NOTE:

AK: indicates the ID of the access key. AK is used together with SK to obtain an encrypted signature for a request.

SK: indicates the secret access key together used with the access key ID to sign requests. AK and SK can be used together to identify a request sender to prevent the request from being modified.
