Message-Level Encryption Keys

When events contain personally identifiable information, such as payment information, the notifications are sent using message-level encryption. Before you can send requests for

Cybersource

services using message-level encryption, you must go to the

Business Center

and create a security key for your

Cybersource

merchant account.

Message-level encryption keys expire after 3 years.

Security keys can be used to make any call, including payments. Treat your security keys as you would any secure password.

You must use separate keys for the test and production environments.
