The txnSessionKey is designed to securely handle transactions within Payrix Pro PayFields/PayFrame integrations.

Unlike the public apiKey, which is vulnerable to bot attacks and fraudulent activities, the txnSessionKey offers enhanced security. Partners can generate keys with various configurations, including default values or customized settings.
