In this section, we explain how to establish connectivity and provide details
on the API design patterns and security model.
API communication details
Communication with the One Time Payment Code API involves transport layer and
application layer security. The transport layer
uses TLS to secure HTTP requests (HTTPS) and the
application layer uses
either PGP or
JWE encryption.
In addition, our Protocol standards to find details on
our API design patterns and strategy for maintaining a robust connection with
partners.
Key exchanges
Encryption keys need to be rotated before they expire or if they are
compromised. As part of your implementation, you need to have a process for
managing these exchanges.
To ensure key rotations do not cause temporary outages or require significant
management overhead, One Time Payment Code partners must support the use
of multiple encryption keys at once. During a key rotation, a second key will
be trusted and verified to be working correctly before the old key is removed.
