Before using the API, the partner shall contact Klavi business representative and apply for security credentials. Security certificates include access key (i.e."AK") and secret key (i.e."SK").

-  `accessKey` is used to identify API reuqester's identity
-  `secretKey` is used to encrypt the signature string and the key of the server-side verification signature string.

Partner must keep safety certificates strictly to avoid leakage.

Suppose that the user's accessKey and secretkey are:

- `AccessKey: AKIDz8krbsJ5yKBZQpn74WFkmLPx3*******`
- `SecretKey: Gu5t9xGARNpq86cd98joQYCN3*******`
